Grant Hoffman recommends:

If Neil had a better board, we should just play 13/8.

With Neil having those three blots, we do not mind being hit. Being hit means we could pick up more blots and increase our chances of winning a gammon. Therefore, plays like 7/2, not fearing being hit, and 13/11 7/4 and 13/11 6/3 could easily be right. Even 13/11 5/2 has merit.

However, Neil does have a broken 5 prime so we should just go with 13/8, as it gives us more rolls to cover the blot on our 7 point, is a slot for the 8 point and gives us more rolls to make the 2 point.

Neil Kazaross plays 8/3 8/2.

An interesting roll since perhaps paying off the 11 number shot is right at DMP, but just perhaps. Here I will lose too many gammons when hit, as my awful homeboard will provide little defense. Therefore, with gammons counting I don’t pay off.

Grant Hoffman recommends: 13/11 9/7

Over the board my play would have been 13/11 9/7. If we look at Neil’s three blots, that says we have a lot of freedom to just make the move that we want to make. Because of those blots, we can move a checker off our 13 point to make it harder for Neil to run of his checkers on his 15 point to safety.

We should play 13/11 then 8/7 and think about the last 1. I decided on 9/8 so the overall move is 13/11 9/7 but trying to make our board better with the ultra-flexible and slightly crazy 3/2 could also be correct. Those three blots give us a lot of freedom.

Neil Kazaross plays 6/4 6/1.

Spare checkers are for handling awkward rolls, so now I can hold everything for another turn. Note that I would be happy to have been able to jettison the 10 point with any safe roll as it doesn’t give me more rolls to clear the 15 point.

Grant Hoffman recommends: 8/3 6/3

To win from here we have to get a shot, hit the blot and then contain the hit checker.

Containing the hit checker is easier when we have a strong board so we should just play 8/3 6/3. XG may like some weird flexible play but making the 3 point has to be correct.

Neil Kazaross plays 7/1.

Blots behind their anchor don’t really matter yet, so I play 7/1 to retain my spare on the 6 point.

Grant Hoffman recommends: Take

A good double by Neil, but he must have been doubling us in, as there is no way this is a Pass.

We have contact against his 10 point and 15 point which means we will have a good chance of get a shot. We also have the start of a good board.

However, if we moved the checkers on his 15 point to his 8 and 7 point this would be a pass. Then if we moved the checkers on his 10 point back to his 11 point, even though our anchor is 6 pips away from his new point, it would still be a pass. If we went back to the original position but move the checkers on his 10 point to his 7 and 8 points, it would again be a pass. Putting all the above together, the most important part of the contact is the two checkers on Neil’s 15 point.

Neil Kazaross plays 8/2.

I want to retain spare checkers in the outfield but not play too awkwardly to my ace point yet, while I await a clearing double. This leads me to play 8/2.

Grant Hoffman recommends: 21/20(2) 6/4

We need to play 21/20(2) — this turns Neil’s spares on the 6, 7 and 8 points into ‘security staff’ (to quote Julius High). All those spares can do is sit there and do nothing.

If we are playing 9/8 6/5, how are we going to win? By entering into some sort of race? After the roll we will be behind 13 pips, so that does not sound like a great idea.

If we play 6/4 we have a threatening board. If Neil hits us with any roll other than 22 we will have a return shot at the hitting checker. And Neil has an inner board blot so we should be more bold. But even if we took a checker from Neil’s 6 point and covered the blot, we should still make the same move as it is consistent with our game plan.

So when behind in the race, seek contact.

A fine roll when I have a race lead. I head towards home with 18/15(2) and 13/10(2).

Grant Hoffman recommends:

After Neil rolled his 61, he now has 10 checkers in the zone, whereas last turn he only had nine checkers in the zone. When your opponent has 10 checkers in the zone, that is enough firepower to successfully conduct the blitz, so we should feel the need to grab the anchor 24/21.

After 24/21 the best available to has to be 6/4.

Grant Hoffman recommends: 8/5 6/5

There are usually 2 reasons for making an advanced anchor:

  • We are about to be attacked, so an anchor is good.
  • We are ahead in the race and would like to have our checkers as far advanced as possible so we can just run with doubles.

Here, after the roll we will be behind in the race by 6 pips and we are not in much danger of being attacked, meaning neither of the 2 reasons above exist here.

We are behind in the race so we need to seek contact. The best thing we can do is improve our board for when that contact happens by making our 5 point with 8/5 6/5. If Neil hits us with any roll except 22, we will have lots of return shots and the stronger board.

I know that for money without Jacoby (as it is commonly played in New Zealand), the correct move is 24/21 24/20.

So what is different here. We are an even number of points away from winning the match, while Neil is an odd number of points away from winning the match. As we are also trailing, we should play the more aggressive 13/10 13/9. We want to turn the cube, win a Gammon and get to 4 away. If instead of being 8 away, we were 9 away, then we should just play 24/21 13/9.

Grant Hoffman recommends: Double

Now we leave a shot with 66, 55, 44, 33, 65, 64, 63, 54, 53 and 43. That’s 13 shots, or 36% of the time. If we get hit with 11 rolls or 31% of the time that’s 36% * 31% = 12% of the time. I cannot see us winning enough Gammons to justify playing on for the Gammon so we should double and collect a point.


Neil Kazaross passes.

The USBGF Members have handled the play on decisions very well this game. Each roll provides a new cube decision and now they must cash.

I must pass since while I may hit them, I can’t hit them often enough to win enough to take.


USBGF Members win one point, and now Neil leads 7-away/8-away.

We could play 4/Off 6/5 but then 66 and 55 leave a shot and most 6’s and 44 leave us odd ended. This is too risky for the small increase in Gammons.

So we have to play safe with either 6/2 4/3 or 6/1. With 6/2 4/3 we have two points with spares on them but with 6/1 we have three points with spares on top of them. Let’s play 6/1 for the increased flexibility but it will be close.

Grant Hoffman recommends: No Double

We are up 24 pips before the roll. No roll leaves a shot. We have numbers that point on Neil. So nothing bad can happen to us but a lot of good things can. So for this roll we are again Too Good to Double.

Again, we are not committing to never redoubling, just for this turn and we will look at it again next turn.

Grant Hoffman recommends:

We leave a shot with only 55 and 65 which is 3 rolls or 8.3% of rolls. If we leave a shot, Neil will hits us 31% of the time on the first roll. So roughly 1 roll out of 36 we will be hit. Playing on for the Gammon is easily a justifiable risk.

We should just play on as we are still Too Good to Double.

Grant Hoffman recommends: 5/4

My gut instinct is 5/4. Some may want to play 6/5 as it guards against 55. That is true, but 6/5 makes 64 leave a shot, and as 64 occurs twice as often as 55, it is better to guard against 64 and avoid playing 6/5.

In one of his articles Bill Robertie warned against “phantom interior gaps” – not having a spare on your 4 or 3 points. He recommended putting at least one checker on your 3 and 4 points.

The other nice thing about 5/4 is that when we clear our 7 point, we will have a more diversified set of spares aimed at the 1 point when/if Neil rolls a single 6 and is forced to run. Then we will have more rolls to point on Neil’s remaining checker.

Our worst roll is 65, but even then Neil still has to roll a 6 and we could get a shot at the blot on his 3 point. This is such a remote possibility that we must still be Too Good to Double.

Grant Hoffman recommends: 12/7 10/5

If Neil’s board was more likely to crumble then we could try 12/7 10/4 killing 6’s but here his board is just more likely to improve, so scratch that.

If we are not playing 12/7 10/4 then the 6 should be played 12/6.

I then concluded that over the board I would play 10/5. However, 7/2 could be right with Neil having 3 inner board blots as it could lead to more Gammons, especially if Neil hits us with a 6 and we return hit in his inner board or at the checker remaining on his 1 point. After the hit if we close out Neil we could pick up around 10% more Gammons. Three blots is a lot but I will go with 10/5.

Grant Hoffman recommends: No Double

What anti-jokers do we have here? I cannot see any. Even 55 which plays 12/2 7/2(2) still leaves us in a very good position. So, this has to still be Too Good to Double.

It is always good to ask ourselves ‘should we double’ every roll that we have access to the cube.

Personally I used to have a real problem with doubling when it was Too good. I used to play in a chouette where one of the players was a millionairess, and she would take anything, especially if she was behind in the score. So I would double late when it was a Pass or Too Good and get a Take 95% of the time. When I realised that I was starting to double too late in matches, I was able to correct that leak. I still doubled her late because it was the sub-optimal play that maximised profit.

Grant Hoffman recommends: 13/5

Most plays are pretty good here. In a chouette this is not something I would argue about.

The best approach is to keep the 6 prime and put the checkers where we want them. As a general rule, we want to avoid putting a spare on the 6 point (here that does not apply) as we will just want to be clearing it soon anyway – if we had a 52 to play we should avoid 13/7 and go with maybe 13/8 10/8.

So I see nothing wrong with just 13/5. As long as we can handle large doubles next turn it looks ok.

Neil Kazaross plays 8/3 7/1.

I want to try to close all my homeboard points and also to have no gaps. I may soon end up having to break my 6 point and want to be able to keep a 5 point board when that happens. Therefore, I want to make sure to make my 3 and 4 points. This leads me to slot.

I vote for 24/16, as we want to avoid getting trapped behind a prime and right now we have some awkward doubles – 33, 44 and 55.

If Neil hits us, it simply does not matter.

Neil Kazaross plays 13/5.

Now I play 13/5, happy that no more checkers will be sent back to increase my chances to lose a gammon. Slotting the 3 point is probably just as good, but I’ll try to make sure that I end up with my 5 point for now.

Neil Kazaross plays 13/7 11/7.

I have 3 plays here and I don’t like any of them.

1) I can make a big ugly awkward stack on my 2 point. This leaves only two shots which is a major plus, but it allows them to stay back and wait for my next roll which will often blot. It also gives me no chance to contain them so they’ll just play on and wait. I have to reject this play.

2) 11/1* leaves 11 shots and knocks them out of their ambush spot in the corner, but they may enter elsewhere and still make my life difficult. This play also gives me almost no chance to contain them and threaten them with cracking at some point.

3) I make my bar point. This leaves 12 shots but at least gives me something that could turn into a threat to contain. Their 55 now breaks their prime. My outfield checkers are closer to home and this could help me save a gammon. It is very difficult to play when primed with almost no counter play, but I’ll make my bar and hope.

Grant Hoffman recommends: No Double

I went through all our rolls and nothing, not even our worst 55 looks that bad. We are still Too Good to double.

I then started wondering how I could alter the position to get it to a state where we would double and Neil would pass. If Neil’s 2 point were instead his 5 point, it’s then double. But not his 4 point, which should still be Too Good to Double.

Grant Hoffman recommends: 13/11 10/7

I looked at this and could not decide which I liked better from 13/8 or 13/11 10/7.

13/8 gives us three builders for the 7 point and means not all 6’s are good for Neil.

13/11 10/7 slots the 7 point and duplicates Neil’s 6’s to hit and cover. If we get hit, we should have lots of return shots.

In a chouette I would go with which ever the team wanted to play. Here if I have to make a choice, I would go with 13/11 10/7 trying to finish our opponent off as quickly as possible.

Neil Kazaross plays 13/11 8/2.

I certainly cannot hit, as I open myself up to many more gammons. I’d only have hit them with boxes. So I’ll cover with 8/2 and then I’ll risk two shots and play 13/11 to get some flexibility and hopefully make another point.

Again we are Too Good to double here, we will win a lot of Gammons.

But we need to remember that “every roll is a cube decision” to quote Kit Woolsey.

Grant Hoffman recommends: 9/4 7/4

The dilemma of when to make your board stronger vs hitting a checker but not improving your board is a difficult one. If we move from 2 to 3 points, we only stop 5 more entering rolls but moving from 3 to 4 points blocks another 7 entering rolls and moving from 4 to 5 blocks another 9 entering rolls – that’s 25% of entering rolls. I tend to make the extra point if it is the 4th or 5th point.

So, here we can make the 5th entering roll so we should play 9/4 7/4.

Neil Kazaross plays b/24 8/2.

My 61 has stopped the blitz, but as I must blot I expect them to play on for the gammon. I’ll play 8/2, leaving the fewest shots and leaving a position where I can hopefully avoid leaving a direct shot next roll if missed.

Grant Hoffman recommends: 13/11 13/10

I would probably not argue between 13/8 and 13/11 13/10 in a chouette but here or for money I would play 13/11 13/10.

First I do not like 13/8, if we make this play 44 hits from the bar. It is only 1 roll, but why leave it when you do not need to? If there was more of a benefit from playing 13/8, we could make that play, but it only gives us two builders for the 4 point. If we moved a checker 13/9 then had rolled 32, then 13/8 would be the play, as then we would have had three builders for the 4 point and this is a clear benefit.

With 13/11 13/10, if Neil enters one checker on the 4 point then we will have a first 6 to hit and then a subsequent 6 to cover. We have also added 52 and 43 to hit loose if Neil enters one checker.

13/11 13/10 would be my two second play over the board.

When blitzing, we do not want our opponent to anchor, here we can stop Neil anchoring by making another point and by putting a second checker on the bar. We should play 8/2* 4/2.

Grant Hoffman recommends: No Double

To quote myself from the last comment: “If Neil does not enter or enters without hitting, we will be too Good to double.” Neil entered without hitting so we are too Good to double.

If we were playing live against a different opponent then I might double if I thought that there was a good chance that they would take.

It is useful to go through the rolls and decide how you would play them. With every 2 except 42 (8/4 13/11) we should hit. Our worst roll is 21 which should be played 8/7 4/2*.

We just have too many rolls here to let Neil off the hook.

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

We have to hit 8/5*(2) then decide how to use the last two 3’s.

10/4 builds a good board but gives Neil the opportunity to anchor on our 3 point. For that reason, we would rather continue the attack. If Neil does not enter or enters without hitting we will be too Good to double. If Neil enter only one checker but hits, then it will be double / take. It is only if Neil enters both checkers and hits that we will not have a double.

Consider the fact that Neil has not extra inner board points, so getting hit back will not be bad.
