playBunny: Gammons are part of chequer play while I'm used to having the cube as a separate deal. I wouldn't say that playing for gammon means a significant difference strategy (though, of course it depends on what makes for significance).

Oh no.....You've disappointed me! But hopefully you corrected your mistake at the last moment....
Of course and game play is very different when someone plays for a Gammon. Even from the start. Trying to close his home board from the beginning, slotting like a maniac(well the maniac goes in desperate situations), playing very aggresively, bringing builders targeting at the home board, double hitting in almost every chance, not paying big attention to splitting, etc.
For example when you are going for a gammon and the start play is 64 then you just make the 2 point! This would be correct in this situation. 43,32 starting rolls call for bringing 2 builders from 13. Even when the opponent starts with 43 and plays both from his 24-point, and then you have 32 for example, a double hit is probably the best move in a go-gammon situation....Also 21 with slotting, although this is considered superior in no gammon-go situations too, 51 with slotting, etc.....
