In Response To: Cleveland -- doubles play w/Mary (Stick)

This play wasn't as blatantly obvious for me as it was for Mary. I realize that us losing a gammon here is costly (giving our opponent's -2 -1 instead of -3 -1 if we were to lose a single) but even with that in mind I had a hard time coming around to anchoring up. The arguments for hitting were so strong I kept rattling them off in my head. It puts us back in the race, we have the stronger board, White has 4 blots floating around take away half his roll and force him to try to consolidate that way, we've made our ace point (ugly!) even though we don't want to blitz/attack it may be our best option. The arguments for making the anchor were shorter, but sweeter. It cuts way down on our gammons lost giving us that long term security and White still has trouble putting his position together next turn. (though he really doesn't need to since we have so little wood up front) We eventually agreed on anchoring up.

The score (after 0 games) is: gnubg 3, kuntvomitt 6 (match to 7 points, Crawford game)

Move number 5: kuntvomitt to play 45

gnubg	153
kuntvomitt	174
