Grant Hoffman recommends: Double

We have the stronger board, with one of Neil’s checker’s on the bar. We are up in the race by 53 pips before the roll. We have threats and at least 9 market losers with no real anti-jokers so this has to be a double.

So ship it and let Neil decide.

Neil Kazaross takes.

A sound double and one I didn’t want to see, but with my high anchor in their 3 point board, I cannot pass it when they have two unanchored checkers back. This is a fine double for them with rather good diversification and threats. I will be most unhappy if they soon make a 4th point and I cannot enter quickly.

Grant Hoffman recommends: b/23*/20

Obviously we need to hit Bar/23*.

Then we should consider 13/10 and 23/20.

13/10 gives Neil a good 6 from the bar, and that is something we would rather not do. He cannot enter with a 6 so his 6’s could be very awkward.

23/20 slots the 20 point, takes aim at any checkers that Neil has to play from his 13 point (that do not go to his 8 point). 23/20 is my quick move but I cannot see a better alternative so will go with that.

Grant Hoffman recommends: 24/21 13/8

First we play 13/8 then consider how to play the 3. If we play 13/10, Neil can hit and escape which we do not want to happen.

24/21 confronts now when we have the stronger board. Even if Neil points on us, we will have many return shots from the bar as we can attack Neil’s rearmost checker.

So 24/21 13/8 for me.

Neil Kazaross plays 13/4*.

I have three plays to consider (hitting both is too loose and strips my 8) and don’t like any of them. 21/16 10/6 is ugly and leaves 15 shots, and if missed, I am still behind in the race and often likely to blot later. Stacking 13/8 10/6 may be a bit better, but is also ugly and certainly isn’t dynamic. Since I expect to play 13/8 anyhow, I might as well look at trying for more with 8/4*. This seems counterintuitive when outboarded, but if missed I am doing fine. I have a 6 to cover my 4 point and if hit, maybe I can anchor or at least enter and make my 10 point. Being behind in the game, I’ll risk mixing it up and hit, and hope they roll a missing 6.

Neil Kazaross plays b/23 8/2*.

I have two plays to consider, noting that breaking anchor is unthinkable. 13/7 is hopeful and enterprising and puts this checker in a good spot, but unfortunately it isn’t likely to remain in that spot. After 13/7, that blot is hit with 5’s and 3’s and my blot on my 23 point can be hit with 6’s and 4’s. This just seems to be too much to me, so as much as it hurts my eyes I have to play 8/2*.

A nice reply to Neil’s 63 split. The standard reply is 8/3(2) 6/1*(2) and that is my choice. If Neil fans we can double him out.

Grant Hoffman recommends: 24/18 7/6

If we stay on the 24 point, we will have to play 7/1, then next turn we will be forced to run if we roll a 6.

Neil can play every single roll safely this turn. So we need to decide whether we win more by staying or running. If we run 24/18 then we should play 7/6 getting a crossover which gets the other checker into our board.

Notice that Neil has a gap on his 1 point and we need two long crossovers to get our checkers into our board. I think we will have a better chance to win by running now than waiting for a possible shot at least two turns down the track. Also if we wait we will probably have damaged our board making it hard to contain any hit checkers, so let’s go now.

We could bring all the checkers in with 11/1 7/2(2) but that is the racing play, and I think we have a better chance of winning by making a strong board with 11/1 7/2 6/1 and hoping we get a shot and hit. If Neil rolls 66 we get a double shot. If he rolls 55 or 65 we get a single shot.

Grant Hoffman recommends: 13/6

If we run we risk being hit, and if missed we will be in a losing race so we have to stay.

Our next job is to cover the blot on our 2 point. Either 11/4 or 13/6 bring another builder into direct range to cover it. 13/6 has to be better than 11/4 as 13/6 gives us 4’s to cover and 11/4 gives us 2’s to cover.

Grant Hoffman recommends: b/24 4/2

We should simply play 4/2 with the 2. We want to improve our board so that if we do get the lucky shot, we have a killer board. We could have an exchange of hits reasonably soon and we might not have covered the blot on our 2 point, but we will still have a 5 prime in place. I think the benefits of improving our board strength are the most important factor here.

Grant Hoffman recommends: 7/2 4/2

My first thought was that we will be ahead in the race by 9 pips after the roll so let’s run. But then I starting thinking that if we play 21/16 13/11, Neil hits us with 1’s and 2’s (small numbers) while his big numbers (that do not contain 1’s or 2’s) are better than normal for racing.

Also we have fewer return shots if we run than when we stay and Neil hits us loose.

It is hard to stay on the point that your opponent wants, but here the alternative 7/2 4/2 gives us a 5 point board, so I will go with that but could be very wrong.

Neil Kazaross plays 11/9* 11/6.

I must hit as I trail in the race and will be an underdog if I don’t hit. 11/9* leaves only a 17-1 joker. After hitting, the only sensible 5 is 11/6 leaving me in great shape if they don’t throw their joker. The seemingly safer 8/3 leaves my position so awkward that it might end up costing me as many gammon losses as leaving the 2nd blot.

Neil Kazaross plays 8/2 3/2.

If this weren’t a gammon save score, I’d make the 2 point instantly to put that dilly on my 3 point to work. Here I needed to look at the safe 11/5 9/8. This still leaves 4 builders for my critical 4 point, but I remain with only a 3 point board and quite a few rolls play rather awkwardly next turn.

So if I leave the 17-1 shot again, how many more extra gammon losses will it cost me? I’m now not likely to lose a gammon unless the 2nd blot gets picked up as well and then both get closed out. If hit, I am 55.5% to enter and 4 of those rolls return hit. My other entries hide my 2nd blot. At most getting hit with a 54 will cost me 2% for gammon losses. Note that I have a 4 point board now which will help me stave off a blitz anytime I can hit from the bar.

Since I think that making my 2 point will add more than 2% to my winning chances, I am taking that risk.

Now with my big racing lead and smooth position, I am a big favorite, so I am not leaving any unnecessary shots. 11/5 9/6 looks good and retains 4 builders for my 4 point.

Grant Hoffman recommends: 24/21 6/4

We would like to win this game and also gammon Neil. If we cannot gammon Neil, we need to at least win the game. Neil has 4 builders aimed at his 7 point, and if he makes it, then it will be harder to escape, so let’s step up with 24/21. We would welcome a blot hitting contest with our side having a stronger board and a 5 prime in place.

24/21 is good for just escaping and winning the race.

We should play 6/4 with the two as we cannot move the two from the 24 point so 6/4 diversifies the two.

Neil Kazaross plays 13/11 13/10.

The themes for me remain the same. Try to contain their straggler and leave few if any shots. Therefore, I play 13/11 13/10.

After the roll we will be ahead by 10 pips. After we enter on the 24 point we should play safe with 11/5 rather than 24/18 which comes out to 4 builders aimed at us.

Neil Kazaross plays 10/5 8/5.

This is a hard choice since losing a gammon means losing the match! Therefore, making my 5 point isn’t automatic. But if I don’t make it, then I am not sure that I am even a game favorite, as I am down 2 pips and they are on roll and my containment chances are then shaky. Also plays that don’t make my 5 point leave me somewhat awkward and I could still roll something to blot and then maybe lose a gammon.

However, 3 shots may be too many. I think I get gammoned about half the time when I am hit or about 4% extra overall. At a gammon go score like this, my gammon cost is 1 as the added cost of losing a gammon is the same equity as the difference between winning and losing the game. So do I think that making my 5 point adds as much or more than 4% to my winning chances vs wimping? I think it probably does since I should be a definite favorite after making that point, as now I have real chances to contain their straggler.

As we cannot escape, I think we should just make our 7 point with 13/7 9/7. Then we will have a 5 prime in place to contain any blot we hit.

Neil Kazaross plays 6/4*/3.

This is all about gaining pips and not leaving shots. 6/4*/3, while somewhat awkward, caters to both of my priorities.

We have to leave our checker on the 24 point alone so Neil has some awkward rolls.

Let’s diversify our checkers by playing 13/10 11/9, giving us more chances of making our 8 or 7 points.

Neil Kazaross plays 13/10(2) 6/3(2).

A very nice roll for me. 13/10(2) is automatic to block their 6’s and to apply pressure to their blot which may soon get pointed on. Now it seems automatic to make my 5 point with the remaining 3’s, but then I look at the position and see 5 stripped points and an awkward stack on my 6 point. I also see that my 11 point is now doing very little because my 5 pt has been made. So then I return those two checkers to the 8 point and look at making my 3 point. This seems to be considerably more flexible and also to have more potential to build a good 4 point board quickly.

What’s not to like about making my 3 point after 13/10(2)? Well, I don’t have my 5 point! But I can often make it soon, and my 11 point now functions as useful builders.

I prefer the more flexible 13/10(2) 6/3(2).

Grant Hoffman recommends: 13/3 8/3(2)

If this were a unlimited game or a normal match score then after playing 8/3(2), we should just play 16/6. But at 4 away 2 away with the cube owned by Neil, we have to consider 13/3. 13/3 must increase our Gammons won. Does it increase our Gammons lost? We do not care if it does, Gammons lost are irrelevant, if we lose the game we lose the match so Gammons lost do not count.

I would not have thought that there would be much in it, but we want to get as much equity as possible, so let’s play 13/3 with the final two 5’s as it must increase the Gammons won.

Grant Hoffman (grant@hoffman.kiwi)

Grant Hoffman recommends: Double

I refer to 4 away 2 away as Super Gammon Go, and conversely 2 away 4 away as Super Gammon Save.

At Super Gammon Go, we are looking for Blitzing or Priming positions with high volatility. When we find one of those positions at Super Gammon Go, we should double.

Here we have priming and blitzing potential. It is easier to blitz when your opponent has only one checker back as they cannot anchor. We lose our market and hit in the outfield with 44, 22, 53 and 62. We also lose our market with 66, 55 and probably 33. This is more than enough to double at this score.

Neil Kazaross takes.

A fine score-based cube but one I cannot even dream to pass. The doubling window is very wide at this score where there are some gammons floating around. Note that by doubling me, they render the extra cost of gammons they may lose as meaningless.

Neil’s Rule of 80 is for this exact score. If the number of total wins the trailer can achieve plus their gammon wins is over 80% then the leader should pass. In this position there’s no way that I can expect to lose 60% of the games nor can I expect to lose 20% gammons. Therefore, I have a trivial take.

When should the trailer cube in the early game at 4-away, 2-away? A good rule of thumb is that they usually want to cube when there’s reasonable gammon chances and the total is 70% or more.

Note that the total at the start of the game is 64%. 50% wins plus 14% gammons and they clearly are favorites here with some market losers.

Neil Kazaross plays b/16.

Not a nice 6 for me, but I don’t want to leave a second blot vulnerable so out I come with B/16. 11 rolls miss and maybe I can survive. If hit I hope to enter and just play.

The normal reply to 54 split with a 22 is 13/11(2) 6/4(2). This wins the most games and the most gammons.

At 4 away 2 away this move becomes even more correct.

My blot on the 20 point is now in mortal danger so I will move it to the 9 point, hopefully out of harm’s way and where it is a builder.

I like the saying ‘if in doubt, rip them off’. I have no doubt here, so we should just play 2/off.

To win this game we need to take all our checkers off before Neil does, and we have just rolled a number that lets us take a checker off, so take a checker off.

We need to play 4/off(2) 6/2(2). We should just take off the maximum number of checkers unless there is a really good reason not to.

Now any 5 or 4 will not take a checker off and cause wastage by moving to the 1 or 2 points – until we clear our 6 point.

Neil Kazaross plays 15/11.

I’m far behind in pips and fully in desperation mode. 15/11 lets me take off 3 checkers with 55 and doesn’t seem worse if I roll the needed boxes. It does play a bit worse if I roll 44 but I need to cater to huge rolls.

Neil Kazaross plays 10/6 8/6.

This looks to hardly matter like many racing plays. The key is to not make clear errors.

I’ll put both checkers into my board and then I can decide whether to play one off the 6 point with a 1 or 2 next roll.

Grant Hoffman recommends: 8/2 6/4

Putting a 9th checker on the 6 point just seems too rich for me. As it is, any 5 we roll until we clear the 6 point, forces us to play 6/1. If we roll two 4’s before we clear the 6 point, then any 4 will have to be played 6/2. Combine bad 4’s with the already bad 5’s, then we are really giving ourselves future problems by playing the two 8/6.

We should be aiming to have an even as possible spread of checkers on the 6, 5 and 4 points. Here we cannot put any checkers on the 5 point but we can play 6/4 giving us three 4’s before we are forced to play 6/2 with any more 4’s.

So 8/2 6/4 is my recommendation.

I still need to diversify and get the most out of big doubles. 13/8 7/5 looks to be slightly best.

Grant Hoffman recommends: 11/6(4)

Moving checkers to the 3 point seems too deep, and the 1 point even deeper.

We have just rolled a number that lets us bring four checkers in exactly so we should just play 11/6(4).

Yes, we will have gaps but Neil will need 8 crossovers to bring all his checkers in, while we will need only 2 crossovers. I think getting all our checkers in is more important.

This play hardly matters as long as I don’t go deep into my board. I want another checker on my 5 point so 15/5 does that.

As Kit Woolsey said ‘When ahead in the race, race.’ After the roll we will be ahead in the race by 13 pips so we want to disengage and play 13/11(4).

Neil Kazaross plays 18/15(2) 13/10 8/5.

I am a pip down after this roll which indicates staying but the timing will be against me as I will be held on my 18 point vs. them holding me on their 11 point with more spare pips to play after the next couple of rolls. This means I should advance my back checkers. So let’s make the best racing play.

That looks like 18/15(2) and then flexibly playing 13/10 and 8/5 crossing over and taking care of my gapped 5 point. The contact in their outfield one checker away hardly matters.

Grant Hoffman recommends: 15/9 8/6

We find ourselves in a racing game. After the roll we will be up 33 pips in the race, and if we win this game we will be 4-away 2-away. So, let’s just race with 15/9 then we should play 8/6, but I could not give a reason why I prefer 8/6 over 6/4 here.

Neil Kazaross plays 13/7(2) 8/2(2).

This is still a holding game, and they have a blotting 61 roll. I’ll make two useful points with 13/7(2) 8/(2) rather than trying anything more clever. I now also have better chances should this become a race.

Neil Kazaross plays 13/8 7/1.

Now I think I should play for more flexibility. If I make my ace point, I may end up with neither my 5 or 3 points made. Therefore 13/8 7/1 stands out. If they roll the horrid 61, every hitting ace allows me to make a 4 point board and that is only a 1.7% parlay. Yes, I play for flexibility and noting the race is getting ever more close.

Neil Kazaross plays 15/13 6/3.

This is a difficult play at this score, as I cannot use a gammon win and hate to lose a gammon. For money, I’d hit instantly and lift 15/13 since 13/11 leaves too many blots when outboarded this much.

But here after 15/13, I took a long look at the position and replies and it just seems prudent for me to wimp with 6/3 winning fewer games but losing fewer gammons. I hope to build up my board soon.

Neil Kazaross plays 22/15.

If we were at a more balanced score, I’d bring down two builders hoping to establish some offense, but here, I think it prudent to hop out 22/15 leaving only 13 shots. This also aims at my outfield where I’d like to establish some presence and where I’d like to hit their lone back checker should it run out.

Grant Hoffman recommends: Double

We are 6 away 2 away. We need to find a position where we can win some gammons, then double. Although this is close, I think this position will do.

We have a three point board. Neil will not be able to anchor in our board if we attack. Neil has only oine inner board point on his side of the board. We are up in the race by 22 pips before the roll. With a weak opponent, we might not double here, but that is not Neil.

Even if this is not technically correct, we should double here.

Neil Kazaross to play:

Neil Kazaross takes.

I have a very easy take here, as my bar point anchor offers good defense and they can neither win this game nor gammon me often enough to scare me into a score-based pass.

Grant Hoffman recommends: 8/4*(2) 6/2(2)

Obviously we are hitting and making the 4 point with 8/4*(2).

For money we should play 6/2(2), improving our board. If we are hit then having a 3 point board is fantastic. We will win more gammons than playing 13/9(2).

At 6 away 2 away, we should be trying to win more Gammons (hopefully with the cube turned), so 8/4*(2) 6/2(2) should be more correct.
