Grant's Puzzles - Backgammon Position of the Week

How should White play 32 here: You were being hammered, and you have just entered from the bar with 32. Because Black has a 4 point board you consider making the anchor with bar/20: The problem with this play is that you will still be behind in the race with your Black on roll. You are only 5 pips behind in the race but this move gives Black the chance to tidy up their position. This is the move that plays to lose respectfully rather than the play that tries to win. If you want to win, you could consider going for the closeout by hitting bar/23 8/5*: The idea here is for Black to miss, then you roll a 3, or 62, 44, 22, 11 or 66. Without counting the exact number of shots, Black hits you from the bar with any 5 or 41, 31 and 61 – that is 17 rolls or 47% of the time. You want to put your opponent on the bar, and cost them the most amount of pips so consider bar/23 20/17*: Now you will only be hit by Black with indirects from the bar. You will be hit with 51, 53, 31 or   11 – that i

 How should White play 21 here: First a reminder that all these positions are played as New Zealand money games, meaning without Jacoby. If it helps just think of it as the first game in a 25 point match. When a giant was confronted with this position, he did not want Black to make a 5 prime so hit 24/21*: This play removes a slot, puts a Black checker on the bar in costs Black the most amount of pips. What is not to like? If Black rolls a 4, then you will have another checker behind Blacks 4 prime. To quote Kent Goulding “4 in a row is more than you think”. This is especially true, the more checkers you have behind your opponent’s 4 prime, the harder it is to escape them. If Black rolls a 3, then they will anchor and that will be the end of your blitz. Any 4 or any 3 is a total of 20 rolls, so 56% of the time you will not be happy. Consider the correct play of 13/11 4/3*: The way to think about this position it is in terms of gameplan. As you, White have made your 2 and 1 po

 How should White play 31 here: You have two choices here. The first one is to step to the edge of the prime with 23/22 11/8: You are way ahead in the race, and would like to escape your last checker and just come home safely. Stepping to the edge of Black’s prime, seems to give you a simple way to win the game – rolling 6 and bring that checker home. The problem with this play is that it diversifies Black’s numbers so that 6’s escape, while 5’s and 4’s hit you off the edge of the prime. If you do not roll a 6 immediately, you have some awkward numbers like 54, and you will be forced to play deep into your board. Then if Black rolls a 6, even if they have do not hit you, they will have control of the outfield. Contrast this to 6/3 4/3: Now you are playing a priming versus prime game. Black will need to roll three 6’s to escape all their checkers. You will need to roll a 1 and then a 6. So, you only need two numbers. You will have more timing here, meaning if you have to move al

 How should White play 32 here: This is from a practice match with a friend. The score has been removed. I have just rolled 32 and we were discussing what was the best move here. You could just make the completely safe play of 11/9 7/4: This is not safe, as you will be behind in the race by 11 pips after the roll, with Black on roll. The future does not look good, as Black will position their 2 back checkers to control the outfield. It will then be very hard for you to run your checkers around, and as you are behind in the race so do not want to run. Threatening to hit one of Blacks blots later, will not be much of a threat, as you will have only a weak board to contain any hit Black checkers. Consider the pick and pass play of 9/6*/4: All Black has to do is enter and they will have a great position. If later you manage to hit and slot at the same time you will only have one checker to cover the slotted point. If Black enters with the 5, you will be forced to tidy up your 2 o

 How should White play 63 here: There is a high quiz factor with this position and over the board most players would simply play 22/13 and pick up their dice. Look at the resulting board: Both players have similar positions. Both players have escaped one of their checkers. Both players will be trying to make more inner board points to prime or attack if their opponent moves their rear-most checker to a higher point. If you do make this play, then both you and Black will still have similar positions. But your position will be inferior because Black has 3 active builders aimed at their 5 point. An active builder is a checker that you can move to make a point without breaking a point. But you have only 2 active builders available for making more inner board points, so you have an inferior similar position. You want to avoid creating inferior similar positions. What else can we do? Consider 24/21 22/16: You have duplicated Blacks 2’s to hit you in two places. If black hits you loose on

 How should White play 41 here: It is a New Zealand money game, meaning there is no Jacoby rule, so you can lose a Gammon without the cube being turned. If you want to hit play here, the best way to do it is bar/24 16/12*: This is the best hitting move as it leaves the less blots. Unfortunately, it still leaves 4 blots around your board. That is way too many, and you are vulnerable all over the board. You will be happy if Black rolls one of the 9 rolls where they cannot enter. When Black does enter, if they hit you, they will be happy but also when Black enters without hitting, they will also have a good position. It is hard to resist a hitting play, but here you should. It would be really nice to make a 5 point, so you consider bar/21 6/5: This leaves only 3 blots but Black has at least 16 rolls that make another new inner board point. If his blitz attack succeeds, they will have enough timing to roll the 2 that they need to play 24/22. This move will lose 19% Gammons. If Black

 How should White play 44 here: Sometimes you have to make the big play and put everything on the line in the next roll. Is this one of those times? You consider 13/9 13/5* 6/2: This does indeed put everything on the line. If Black rolls a 5 you will be on the bar against a 5 point board with 2 other blots lying around in danger of being hit as well. Those blots put you in danger of losing a lot of Gammons here. The advantage of this play is that 62 also covers your 5 point if you are missed. That is not enough compensation. You consider leaving less blots with 13/5*(2): Now if Black rolls a 2, it will be a little bit harder for Black to escape from behind your broken 5 prime and you will have only one other blot in the outfield. But Black still has a 5 point board, and that should scare you. I want to be ahead in the game without risking any checkers being hit, and therefore minimising my gammon losses. Consider 13/9(3) 6/2: You will be ahead in the race by 16 pips after the r

 How should White play 61 here: You could just make the completely safe move here and play 13/6: The ability of Black to escape their last checker should be your main concern here. The problem with this play is it does nothing to stop Black escaping. Next turn Black will either run into your outfield or run into their outfield. Neither of those options should be appealing to you. It is easy to think that the three checkers on your 24 point are your main concern and play 24/18 24/23: The problem with this play is that a lot of small numbers now become good rolls for Black. You are mainly concerned about having 3 checkers on your 24 point when Black has other inner board points made, which makes it harder for you to split off your 24 point. Here with Black only having the 6 point made, there is not as much urgency to get off your 24 point now. You would still like to, but you are not desperate to do it this roll. What about hitting 6/5* and moving 24/18: This does make it harder
