Introduction

In another complicated game with many difficult play decisions on both sides, Royset gains an early advantage and doubles somewhat prematurely. His dice cooperate however and he pins Tissona down in an ace-point game. Tissona is forced to break up his board and loses. Score: 5-4 Tissona.

Annotation

Casper van der Tak: This is a close decision. 13/1*(2) puts Royset on the bar, while 13/7(2) 8/2(2) makes two better quality points. Without other targets, the quality of the points wins out narrowly.

Bots: Snowie liked the move played, but GNU thought 13/1*(2) was slightly better.

Annotation

Casper van der Tak: 24/22 6/4(2) is as good as forced. After that, I am surprised that 13/11 would be better than 8/6, afterall, 8/6 balances the position and leaves no shots, while 13/11 leaves 6 shots and starts stripping the midpoint which seems a high price to pay for an additional builder.

Annotation

Casper van der Tak: Alert play by Tissona. Some 3s already play well for Royset (31, 53), while Royset does not have particularly productive 2s. An additional advantage of 24/15 over 23/14 is that 65, not a particularly productive roll, plays much better for Royset after 23/14 than after 24/15.

Annotation

Casper van der Tak: The duplication of 31 is very real; does Royset want the hit or the point?

When I saw this position, I figured that hitting was clear. After 13/10*, 10/9 seemed like the easy ace. Hitting turns out to better in the rollouts, but it is not as clear as I thought, and the ace is not right. 8/7 turns out a bit better than 10/9. I still don't quite see it.– There is some duplication of 5s, but getting hit seems costly, and it is 11 hits vs. 4 hits. To me, it seems too high a price to pay for additional point-making opportunities.

I have no reason to believe that the rollout is wrong, so 8/7 must be better than 10/9, but know that I'd play 10/9 unless I had gained a better understanding through manual rollouts.

Bots: Snowie thought the move played was a mistake and suggested 13/10* 6/5 as the best play, whereas GNU thought 8/5 6/5 was best.

Annotation

Casper van der Tak: Close between B/20 8/2* and 20/14. I guess I agree with Royset's play, which gives a better chance to get another shot at the checker that Tissona tries to bring across. 20/14 has the advantage of contesting outfield control and leaving the spare on the 8. Tough decision.

Casper van der Tak: But this is pushing it! Royset's advantage is the better board and the initiative, but Tissona is not yet on the bar, and Tissona leads by 21 pips. Since Royset has only a three-point board and 10 checkers in the zone with three back checkers, a blitz will be difficult to run and complete. No double and easy take.

Annotation

Casper van der Tak: No matter what Royset does, his first two 6s should be 13/1* to put a second checker up against a 4 point board. After 22/10, he will have 13 checkers in the zone, meaning that he can with stand one hit and still be able to close-out Tissona with the material already at hand. The text play is much too soft.

Annotation

Casper van der Tak: Put your checkers where they belong! The ugly third checker on the 2 belongs on the ace. Tissona has the chance to move it there, so he should grab the chance to do so. After that, both 8/5 and 6/3 have merit. I'd play 8/5, but the plays are essentially equal.

Annotation

Casper van der Tak: Now that Royset has a 6-prime he has no reason to move the checker on the 16 point. Royset hopes to pick up a third checker, which would increase his gammon chances, or more likely to force Tissona to play awkwardly to avoid shots – breaking his board and reducing his chances after a hit.

Therefore, Royset maintains an outside 6 so as not to be forced to run next turn. Royset also does not play 16/15, to maintain maximum contact. These considerations rule out 9/5 8/7 and 9/5 16/15. There are two remaining contenders: 9/4 and 8/3. I'd play 9/4, keeping the spare higher in the board.

The differences between the plays are not very big because Royset can only conveniently stay next turn on 61 and 62.

Annotation

Casper van der Tak: Tissona has two objectives here: buying time to prevent being forced to leave a shot on the midpoint, and maintaining as much as possible of his board. His play saves one 5 and two 4s, so he significantly reduces the chances of being forced to leave a shot on the midpoint. However, his play isn't as good for maintaining the board. If he needs to play a 5 and a 4 inside his board, he will only have a three-point board left. Best is 6/4 5/4, which saves a 5 and a 4 in case one is needed, and crunches down to the lowest four point board possible, which is the board you will be able to maintain the longest. A case of crunching from the back.

Having both the 6 and 5 slotted also means that it is possible to rebuild the board as soon as possible.

Casper van der Tak: The same principle applies here, and 6/1 5/4 is better than 6/1 4/3. The difference is more considerable than one would think, but leaving the 5 slotted allows some sequences in which Tissona has a 5-point board when hitting an early shot.

Casper van der Tak: Another small technical issue, 6/off 4/3 does not leave an ugly stripped 3-point compared to 6/off 3/2. Stripping the 2-point is not as bad since Royset has more time to rectify this before it harms him.

Annotation

Casper van der Tak: Wasting pips may cost Tissona the gammon if he gets pointed on, and the home board blot is also a mixed blessing. While it can sometimes be covered before hitting a shot, in most cases it will be there to be picked up at the wrong time. 24/14 is better.

Annotation

Casper van der Tak: I think Royset can play more aggressively for the gammon: 4/1* Even after Tissona hits and Royset dance, Royset remains a favorite, and the play picks up a lot of additional gammons. Not clear cut, but I believe the more aggressive play is better.
