2022 - Position 166

XGID=-b----E-C-B-cC---d-db---B-:0:0:1:21:0:0:3:0:10

There are four sensible plays here. 13/11, 6/5; 13/10; 24/23, 13/11 and 24/21.

The final three are pretty much tied in terms of equity but XG rates them all small errors. 13/11, 6/5 is the winner. Taking a risk now in an attempt to equalise the position is just worth it. White has ten checkers in the attack zone, so splitting is somewhat risky.

I got this wrong over the board by playing 24/23, 13/11 so I definitely learnt something from this long rollout.

Unlimited Play. How should Red play 21?
