Otsikko: hit or run ?
i am bearing off already, 1 piece of me is on the bar, my opponent isnt bearing off yet but has some pieces back to send me to the bar

i can send one of the pieces of my opponent to the bar .. but i can also leap over it

what should i have done ?
(i sent his piece to the bar)

the position can be found here : Backgammon (Hrqls - incognito)

Hrqls: That is a tough call... but to me, i think you should have skipped over it. Putting him on the bar takes away his double 1 roll, and his 2 1 roll from hitting you, but any other 2 roll hits you anyway, and then you still have that one checker left around to get you later.... I think though it doesnt really matter, since it is only a matter of some time before you win this one no matter what!

Hrqls: Hit everything and fry up some gammon! except that gammons don't count, so just hit and have fun. It's Hypergammon with 1 man versus 4. He doesn't stand a chance.

Hrqls:  Took me a minute to figure out that the 4-2 wasn't your roll.

I agree with Czuch, there's nothing to be gained by hitting.  You're already well ahead in the race and you have no board.  Your one goal is to get past his back men, and hitting makes that harder, not easier.  Unless like you he rolls double aces and dances against a one point board ...

Sure there is. Fun!

Is that true, though? It's not just getting past his back men, it's getting all his men off before the opponent does. Failing to hit gives 19 pips to the opponent. How many rolls would that save the opponent in equalising and getting ahead? That must be weighed against the extra chances of 4 men and a one-point table detaining the blot sufficient to win.

Actually, one possible continuation after not hitting is that the opponent rolls 2-4 and moves 12/10*/6 to make the 6-point. But even if it's a non-hitting 6, that's the 6-point made. Thus, after not hitting, 17 rolls will give an immediate two-point home table. That's four times the chances of dancing, and the splendid 6-6 off the bar is lost.

there's nothing to be gained by hitting.

Sure there is. Wins!

Why don't you ask gnu?
