Bringing checkers home
Whats your move? White has 4-2 to play.

Am I missing something? This seems pretty obvious - we want to minimize rolls that opponent can hit with. Obviously we want to move our blot on the 18 point to remove the direct shot. We don’t want to play 15/11 with the 4, so we either move 18/16 or 18/14. With 18/16 we will have to move that same checker to the 12. With 18/14 we can combine with 3/1 or 15/13.
With 18/12 we are hit when opponent throws a 7 or 10, so 61,52,43,64, or 55 - 9 rolls
With 18/14 15/13, we get hit by 9s or 8s- 63,54,62,53,44 33 or 22 - 11 rolls
With 18/14 3/1 we are hit by 9s or 10s - 63,54,33,64, or 55 - 8 rolls, so that seems like the best move.
Edit - we also could consider 18/14 4/2 as well. I think that is likely close to 18/14 3/1 but keeping the 4 point is probably helpful in variations where we have a chance to hit red’s blot and keeping the second checker there probably gives a more efficient bearoff if red rolls a big double and makes the race close, so I’ll stick with 18/14 3/1
Yeah, you used pretty much the same reasoning as I did while playing. I played 18/14 3/1. But this is not the best play. It was around 0.060 error at the score I believe. But it is also error if it would be 0-0. It is a bit tricky play, yes, thats why I am putting it here 😀
I let you try to figure it out for some more time 😉
I’m grasping for straws on this one. The only thing I’m coming up with is that if we leave the 18 point blot where it is we get a chance to hit if white rolls a 66 to take the race lead. If we move the 15 point in that case we leave a double shot, so I would guess 6/4 6/2 since you told me it’s a tricky move. That’s probably wrong, but like I said I’m grasping at straws here. I would never have found that move OTB,
