In Response To: Crawford Backgame (Ian Dunstan)

Looks close for 2nd, but not for 1st.

It's the backgammons. Note the hitting plays do as well (actually a bit better, within uncertainty) as the 24/23 play. But at this score the fraction extra wins isn't enough to overcome the BG losses.

The score (after 0 games) is: JellyFish 4, Player2 10 (match to 11 points, Crawford game)

Move number 5: Player2 to play 41

Pip counts: JellyFish 126, Player2 187
Position ID: 2G40gwBoTzCANQ Match ID: 8AlmAUAAUAAA

• Player2 moves 8/7*/3
