In Response To: 62S 61P 41 - What's your play? (ah_clem)

I played U ( bar/20 ), reasoning that since the checker was just as likely to be attacked on the 21 as the 20 I might as well slot the better point. Thanks to David Rockwell for pointing out that while either point is about as likely to be hit, hitting on the 20 is more advantageous for my opponent than hitting on the 21. Thus, gnu likes entering on the 21 and then doing something else with the ace.

W and V are statistically tied at this rollout setting. I'll invite anyone with XG to do another rollout and see if it has a different opinion.

The score (after 0 games) is: gnubg 0, you 0 (match to 5 points)

Move number 4: you to play 41

gnubg	160
you	166
