Grant Hoffman recommends: 24/13

Neil has 3 builders aimed at his 7 point and his 8 point slotted. We want to hit to stop him making one of those points but he has a stronger board. Because of his board we are forced to play 24/13 and hope for a better roll next time.

Neil Kazaross does not double.

This is a huge money pass, but at the score the USBGF Members have tremendous recube vig due to overage, my then dead cube and my then useless gammon/backgammon wins. I’ll play it safe and roll.

Although we should hate to put a third checker on the 24 point, we simply have to hit here to stop Neil making his 8 point.

Neil Kazaross plays b/23 13/9.

After entering b/23, my clearly best 4 is to bring down a builder with hopes to soon add another good point or two to my structure.

I know that we are supposed to play 2 checkers off the midpoint, but it must be close.

I am so used to playing 24/22 13/8 that I would probably still do that. If the score was 6 away 2 away to Neil, I would definitely recommend 13/11 13/8 but here let’s stick with 24/22 13/8.

Neil Kazaross does not double.

Perhaps this just barely qualifies as a money double. Therefore, I have nothing close to a cube at this score.

Neil Kazaross plays 8/4 6/4.

I am happy to make my 4 point as they are on the bar. It is worth a few return shots to make a considerably stronger board.

We should play 5/2*(2) with the first two 3’s. It is good to put Neil on the bar.

I like taking two more checkers off with 3/0(2) as the more checkers we have off the better. We will win more gammons if not hit, and more games if we are hit.

Neil Kazaross plays b/22 7/6.

Now I think I need to play 7/6 rather than 4/3 as after 4/3, there are only a couple 6’s that allow me to stay next turn without breaking my board and the lost crossover could result in a bit more fluke gammons lost.

For money, I would pay later with 7/1 6/5. I hate the thought of Neil rolling a 62 and hitting us. 10/4 6/5 gives us a better distribution, but when since Neil owns the 23 point anchor we would like to strip the 7 point and clear it fast.

Here it is probably slightly wrong to play 7/1 6/5.

Neil Kazaross plays 11/8 11/5.

There won’t be much if any meaningful difference between the top 3 plays. I’ll avoid 11/2, as I see no reason to put a checker on my 2 point yet. 11/8 11/5 retains two 6’s before I am forced to run from the 23 point, but these 6’s are forced to my 2 point and if they come with large numbers I may have to break my board. But if they roll small numbers, I really don’t want to be forced to break anchor as they’ll have builders ready to close me out. 11/5 8/5 seems less awkward and perhaps is best, but the difference has to be tiny. I think I’ll save a 2nd 6 since my 5 prime board will often result in a win if I can hit soon.

Neil Kazaross plays 8/2 5/1.

I certainly don’t want to run yet, so my 6 is 8/2 and then I have to decide whether to slot my ace point. If I slot, I’ll retain a 6 to play rather than being forced to run, although unless I roll 61 I will be forced to break my board if I don’t run. If I slot, I have 15 rolls to close my board vs. only 7 if I play 8/4.

But if I slot, I have to worry about covering if I hit, but I’ll have a 5 prime board and they’ll have broken their board so I may end up ok even if they return hit.

I also need to have a closed board to consider recubing for match if I get a quick hit.

I will play the slot.

Neil Kazaross plays 23/18 8/5.

If I don’t run I must break my board and I don’t want to do that. If I do run there are only two builders to hit me. So I hop with 23/18 and bring in a builder for my ace point with 8/5 even though I don’t yet expect to waste pips with 5/1 to cover. But if I have hit a blot, I’ll certainly cover with a 4. Of course, I’ll cover with a 1 regardless.

Neil Kazaross plays 12/7 5/4.

They now have significant chances to blot over the next couple rolls, so I think it is best to not be forced to run away with my next 6. Therefore, I’ll waste a pip with 12/7 5/4 as I am very unlikely to lose a gammon anyhow and my bearoff isn’t made much worse by 5/4 if I hit.

Grant Hoffman recommends: 9/6 8/5(2) 7/4

We obviously have to make the 5 point with 8/5(2).

The 7 point is always dangerous to own when our opponent owns the 2 point anchor – see Kit Woolsey’s excellent article ‘Bearing in Safely’. So we want to strip the 7 point with 7/4. That leaves only 9/6 as a viable fourth 3.

So 9/6 8/5(2) 7/4 is my choice.

Neil Kazaross plays 7/5 7/3.

Making my 4 point seems best for closing my board eventually. But if I leave 2 blots in my board, I fear that they will leave me an indirect shot with some rolls to smooth out their position. So I think it seems best to just cover my slots.

Grant Hoffman recommends: 7/5(2)

After the roll we will be ahead by 20 pips. Therefore we do not want to make the 20 point as we will have made it hard to escape with Neil having his 11 point. If we then do run off the 20 point, Neil will be able to attack us with the checkers from his 11 point. So stay away from the 20 point.

If we slot our 5 point we could be hit so why not just make it 7/5(2) and only leave indirect shots? We will have 3 builders for the 7 point. This leaves us a good flexible position with a strong board.

Neil Kazaross plays 7/2 6/2.

Here I can make my 2 point or play two checkers from my 6 point, remaining more flexible but leaving two blots. If I leave two blots I have nothing to deter them from doing whatever they want. Therefore, it seems clear to me to make my 2 point.

Neil Kazaross plays 8/3 6/5.

6/5 is a must to slot my 5 point and then I think 8/3 is more likely to enable me to make a full board than playing any other 5.

Neil Kazaross plays 13/7 10/6.

I haven’t been able to accomplish much of anything for a while and now have to play 13/7 10/6 and hope for better rolls soon.

Neil Kazaross plays 13/11 13/10.

Taking a look at all the rolls I think it is best to risk 5 extra shots in an attempt to better be able to contain their back checkers if they roll poorly. Note that after 13/11 13/10 their hitting 54 and 53 rolls can also be used to make a full prime. I will win a few more games after the building play as compared to wimping 13/8 but also lose a few more gammons. However, my gammon cost, while higher than at a routine score, isn’t huge.

Grant Hoffman recommends: Double

We need points, and we hit with 63 and 64. We have rolls to make our 7 or 5 points. Neil could end up in a 23 point anchor game. We are up in the race by 14 pips before the roll. I double.

Neil Kazaross to play:

Neil Kazaross takes.

I have a very easy take here as while my position is clearly inferior, I have plenty of chances to improve it. Their builders are threatening but not guaranteed to make new points. My anchor on the 23 point will cut down on my gammon losses.

Grant Hoffman recommends: 10/4 6/4

This is really tough. My instant response was to make the 7 point with 13/7 9/7. This duplicates 1’s and starts to block Neil in. But we are ahead in the race, so that also argues against priming.

However, we are 8 points away and could use a gammon so 10/4 6/4 has to be more Gammonish.

I am really torn here, but we really need Gammons so 10/4 6/4. It is also good to retain our midpoint, and if in doubt make a point.

Gus Hansen has asked his opponents which move they would prefer him to make when he cannot decide. He then makes the move they want. In the next live tournament, I should take a coin out and toss it to decide.

Neil Kazaross plays 11/7 8/7.

Rather than panicking and hitting both checkers in an attempt to gain a tempo, it seems considerably better to just build my position. Making the bar point also leaves 7 fewer shots than the double hit.

Grant Hoffman recommends: 8/5(2) 6/3(2)

We obviously have to play 6/3(2) then decide on how to play the remaining two 3’s.

For money, we should play 8/5(2) giving us a great board. This puts Neil under the most pressure. It duplicates 61, 63 and 64 which are already good for Neil.

Stick once wrote ‘if in doubt, make the 5 point. When it is right, it will be right by a lot, when it is wrong it will be wrong by only a little.’

So if that’s what we should do for money, so here trailing in the match, at a multiple of 4 away from winning, we should definitely make the 5 point.

Neil Kazaross plays 24/23 13/11.

My 2 played from 13/11 makes a hopefully useful point, and then my ace must be 24/23 anchoring to prevent their builders from blitzing me.

Grant Hoffman recommends: Pass

Oops, we are on the bar against a 4 point board. Some of our entering numbers 61, 51 and 31 either leave us with an inner board blot (so Neil can easily attack) or leave a direct shot.

Also a gammon wins the match exactly for Neil. We should let this go. That was my gut instinct and nothing about this position makes me want to do anything else.

Neil Kazaross comments on the cube:

I have a big advantage here but I don’t think I am too good, noting that their 4 point board can provide counter play if I get hit. I’d be too good if my back checkers were somewhat closer to home.

This is a big pass and I can win quite a few match ending gammons if they take.

Neil Kazaross wins one point and leads 3-away/8-away.

With this roll, we are now 11 pips ahead in the race after the roll. So we should play 2 checkers 14/10(2).

Next we should improve our board to a 4 point board with 8/4(2). If Neil hits loose, we want to have a board with bite — a board that would either discourage Neil from hitting or if he does hit, makes our return hits more deadly.

Grant Hoffman recommends: 8/4 6/5

We are very close in the race but I want to avoid any play that involves 24/23 because if Neil makes his 8 point, the new are blocked 6 pips away.

Initially I really liked 14/13 14/10 but the 14 point makes it harder for Neil to get by us and gives us another point to run to with our back checker.

Our boards are roughly the same strength so I think I like 8/4 6/5, preparing to improve our board and if Neil hits us we should have return shots.

I am unsure about this move but if the clock was ticking, I would make this move.

Neil Kazaross plays 10/4 6/4.

I have to blot no matter what. If I hit 8/2*, I have nothing resembling a good 2. Therefore, I play 10/4, and then making my 4 point looks stronger than making my 8 pt. I leave 15 shots, but they will be in serious trouble after the 16 small rolls that keep them under much pressure on my 2 point.

Grant Hoffman recommends: 13/5(2)

For money, the best play is 13/5(2), improving our board. Then, I would hope that Neil leaves a direct shot with 63, 62, 54, or 51. He would leave an indirect with 53 and his 21 is safe but awkward with 6/3.

Here at 8 away 4 away, we have even more incentive to play aggressively so 13/5(2) is my recommendation.

Neil Kazaross plays 13/10(2) 8/5(2).

Two plays here: Either I make the bar point and leave no shots, or risk 4 shots and make my 5 and 10 points. My potential to improve from making my 5 and 10 points seems worth the shots, and their hitting 61 plays OK anyhow. This more aggressive play should garner me more gammons and it is no disaster to be hit.

After this roll we will only be ahead by 2 pips, which means we are slightly behind. Therefore, we should keep maximize our contact and make a blocking point by playing 20/14(2) 8/2(2).

Now we have the same number of checkers off and I lead by 7 pips and have no real defects in bearoff structure.

Neil Kazaross does not double.

I’m ahead 3 pips in a medium length bearoff so I should be close to a cube except for two things. 1) My extra checker. 2) My lead in the match.

I just can’t win this game often enough to justify cubing.

We should just play 9/6 here. If there was a gap on our 4 point then the play would be 9/7 5/4.

Neil Kazaross plays 8/5.

8/5 looks to be a bit better than 9/6 in that it is less likely to run into issues with missing 5’s later.

Grant Hoffman recommends:

We have to play 7/6 to get the crossover. 14/9 puts a second checker on the 9 point which is not very flexible so we should play 9/4. If we had a 4 to play instead of a 5, 14/10 looks best as it is diversified and more flexible. It will probably be close.

Neil Kazaross plays 10/4 9/5.

9/5 is a must to fill my gapped 5 point and then 10/4 has to be the best 6, not yet going too deep into my board.

Neil Kazaross plays 8/3 6/5.

My ace should go 6/5 trying to mend the weakness on my 5 point. Then I slightly prefer to diversify a bit with 8/3.

Grant Hoffman recommends: 12/11 8/6 7/6

After the roll we will be ahead by 12 pips, so we should be trying for a racing game plan. This means we should get 2 checkers into our home board with 8/6 7/6.

For the final 1, playing 12/11 means we get another checker in with a 5 or 6.

Neil Kazaross plays 9/3 4/3.

I still want to try to contain their back checker so I keep my semblance of a blockade. Therefore, I’ll play 9/3 and find an ace. The most flexible and best ace for the bearoff is 4/3.

Neil Kazaross plays 10/4 2/1.

10/4 is basically forced so let’s look at my aces. I think 2/1 is slightly best, putting that dilly builder on a new point. Since my checkers that are beyond my open 5 point are all well placed to get there, I can play 2/1.

Grant Hoffman recommends: 24/12 8/2(2)

Before the roll we were behind 13 pips in the race, after the roll we will be ahead by 11 pips. Running is now a viable game plan so let’s get our back checker out of dodge by playing 24/12.

Our checker on the 20 point is still in danger and Neil will hit us if he gets a chance. We want to make any of our return hits as fatal as possible, so let’s improve our board by playing 8/2(2). Then we will have a killer 5 point board.

Neil Kazaross plays 11/9(3) 4/2.

I can’t afford to hit loose since after continuing on to my 3 point, I leave 13 slightly gammonish shots. Also, this play is not decisive if it works since they can enter and still run away later. So I have play 11/9(3) and then 4/2 looks best keeping a builder.

Grant Hoffman recommends: b/20 8/2

In this type of position, the default is to slot the next point in our inner board with 8/2. We will have a board with no high gaps if we make the 2 point so this looks good for me.

13/7 will probably be close or maybe even better, certainly I would let my partners in a chouette do whichever move they wanted as it should be a close call.

Neil Kazaross does not double.

I might have a cube for money, but with this lead in the match I will be cautious and hold off. I can lose quickly by getting hit, or later by losing race, or even to a 20 point holding game if they make that anchor.

8/4 6/4(2) makes a useful point and keeps my blocking points which are also threatening builders if they don’t anchor.

After the roll we will still be 4 pips behind in the race with Neil on roll. Therefore, we are not aiming for a racing game plan. So we should play a checker to Neil’s bar point by playing 23/18. This makes it harder for Neil to make inner points with rolls like 51, 62 and 65 as now we will have a direct shot. This is the classic ‘distraction’ play. This encourages an exchange of hits, so we need to improve our board by making our 3 point. If we make it with 8/3(3) we create a dilly builder and give up the 8 point so instead let’s play 13/3 8/3. We make the 3 point and retain the 8 point.

Neil Kazaross does not double.

I wouldn’t consider cubing this for money so it must be a huge blunder at this score, where I can face a 4 cube if I roll poorly. I simply can’t win this game often enough to cube yet and need to make a good point and then reconsider.

Neil Kazaross plays 8/2* 6/2.

I’ve often said, that when you really don’t want to be hit, leave fewer or better yet no shots. Therefore, I make the 2 point which also puts one of my 6 checkers on the 6 point to work. This leaves no blots and safely retains spares to make other points.

Grant Hoffman recommends: 24/21 6/4

Anchoring up looks bad to me as Neil will tidy up his 10 point blot and then be able to reach a point where he can double.

6/4 has to be the 2, giving us a stronger board or a ‘board with bite’ to quote a friend.

8/5 looks ok, but how do we intend to win this? The question I ask myself a lot. We need to confront Neil now with 24/21. Yes, I know that is stepping under the gun with 4 builders aimed at us. But that is my move, and in a chouette if it all went wrong, I am sure the others would think me crazy but it puts Neil under pressure right now.

We ask ourselves: how do we intend to win this game? We cannot prime Neil, and we are behind in the race by 15 pips after the roll so racing does not looks bad. The most likely way that we will win this is if we get a shot, hit the checker and contain the hit checker.

We do not have a shot now, so we should work on containing the checker when we hopefully get the shot and hit the checker. This means we should build our board now. So we should play 6/4 then play either 8/3 (my preference) or 13/8. I would agree with either in a chouette if my partners felt strongly about either play.

Neil Kazaross plays 13/8 10/6.

This may be my least useful roll and makes me happy that I didn’t cube. Especially at this score, I felt that I needed to make a good point first, and then consider whether to cube.

I am now up 24 pips and out-boarded as well and don’t want to be hit as all of my checkers are at least half way home. This means play to not be hit. I leave only 9 shots, with the ugly 13/8 10/6 and if hit I have quite a few return shots. This also retains my builder structure for next roll.

I recommend my normal opening 51, which is to slot. Even here being behind in the match it may not be correct, but that is my play. If Neil misses, we get the chance to make our 5 point.

Neil Kazaross plays 24/21(2) 13/10(2).

The correct play for money is to make the 21 and 10 points, and at this score where I don’t want to face gammonish cubes, this also must be correct.

Neil Kazaross plays 21/11(2).

When ahead in the race, one should usually run. 21/11(2) leaves me ahead 22 pips and with an outfield structure of points that functions as builders as well. I call this type of game that I will now have “15 vs. 2.” If I can soon make a point or two in my board, this position shouldn’t be too hard to bring home.
