In Response To: Quick Quiz #2 (Ian Dunstan)

I still haven't had time to go back and post my thoughts on the first quiz but I'll do this one in real time.

Position 1




White is Player 2

score: 0
pip: 144
1 point match
pip: 157
score: 0

Blue is Player 1
XGID=-A---aDaB---cG---d-ea----A:0:0:1:44:0:0:0:1:10
Blue to play 44

eXtreme Gammon Version: 2.19.206.pre-release

Having recently written an article on gammonvillage about covering the ace point as soon as is conveniently possible I had to pull myself back to even find another play. Even though the midpoint is wildly stacked putting a man in the air has a huge swing on the four fanning numbers. On top of that, it certainly makes the position harder to clean up for the opponent, less covers and impossible to safety all his blot. Still seems clear to me.

bar/21 13/5*/1

Position 2




White is Player 2

score: 1
pip: 150
5 point match
pip: 135
score: 0

Blue is Player 1
XGID=aaB-BBBBAa-Aaaa---bbcbAB--:1:-1:1:61:0:1:0:5:10
Blue to play 61

Even though there seems to be a lot going on here I only see two candidates. Both candidates play 23/22 with the ace anchoring up. The only question to me is do we hop out 23/17 or do we hit on the ace point? Once I count the number of return hits from the bar anyway if we don't hit on the ace point I don't see a downside to hitting on the ace point. The opponent has a slew of blots around for us to gobble up like it's 1982 and Ms. Pac-Man was just released. I doubt the score affects the correct play but if it does I also think it would push us towards this play with the higher gammon value.

23/22 7/1*

Position 3




White is Player 2

score: 0
pip: 76
3 point match
pip: 71

Blue is Player 1
XGID=-DBAaBB--BBa-------abbccb-:0:0:1:00:0:0:0:3:10
Blue on roll, cube action?

The take point at 3a 3a is a bit higher, around 25%. There aren't many gammons floating around anyway so that piece of info hardly matters. I would approach this first using O'Hagan's Law even though it is only meant for money like scores. How many market losing sequences can I come up with?

[66 44 61 51] almost for sure. That's six already. On top of that I see a bunch of potential market losing sequences like [65] and not being hit back or [55] and the same or [64] and he doesn't escape etc...Certainly over the nine sequences needed to cube for money and we don't have any horror rolls thus...

Double

Position 4




White is Player 2

score: 2
pip: 149
9 point match
pip: 138
score: 0

Blue is Player 1
XGID=---b-bD-F----DA--cacb-b---:0:0:1:55:0:2:0:9:10
Blue to play 55

Well this certainly is a nightmare. Two of them seem forced to me, 14/4. Leaving that blot out there is 6 shots anyway playing those two fives somewhere else is awfully fugly. I feel like one of the remaining fives must be played 13/8. We aren't going to make our ace point and strip two men from the six leaving us less flexible and less covers for the now slotted four point. The last five then? I'd keep the flexibility and play it down from the eight point also.

14/4 13/8(2)

Position 5




White is Player 2

score: 0
pip: 118
3 point match
Crawford
pip: 80
score: 2

Blue is Player 1
XGID=-C-BBbB-CC--b---a--cbbab--:0:0:1:21:2:0:1:3:10
Blue to play 21

This and #1 are (hopefully) easy. I see no reason to skip making the bar point. It will close that gap and make it easier to clear the other further reaching points. This is not a case of making a point we don't want.

9/7 8/7
