What's your play and why? //Walt If I've read it right X's home table is bottom right and O has one checker on the bar ??? If so, my play would be one checker from 6 to 4 and one from 13 to 7. X is well ahead imo and should play safe, both moves make "spare" pieces available to cover another point in the home table, the only risk being that if O then throws a 6 and either 1,2 or 5 then they can hit 7, but the O home table isn't very strong so should be easy to get back on... |

My style is to build a wall and block out one or two shooting for gammons. But, then again, I have never played for money. |

A friend and I played a lot for a couple of years for a penny a point and I nearly always won over the course of a couple of hours. We stopped playing after he threw the board up in the air and scattered pieces all over the pub after another loss |

I don't know how match play works, but backgammon without the doubling cube and a small stake is boring, as I know when I play waife or kids... |
