1. White has two dead checkers but still has a three-point board. The race is close with Blue having three checkers back. This is shaping up to be more of a priming game than a blitzing game, even though White is temporarily on the bar. Blue's structure gives him a clear advantage but because his checkers are so far back, it will probably take him a while to make another point in his prime. I think this is D/T.

2. White's timing isn't ideal but I think she can take comfortably. The position isn't very volatile so I don't see the need to double. ND/T.

3. There are plenty of market-losing sequences (if Blue hasn't lost his market already) and Blue isn't TG so I would double for sure here. White gets a single direct shot if Blue rolls 54 53 52 43 32 and a double direct shot if Blue rolls 41 31 22 21 11. I estimate that she gets a shot and hits it 9 times out of 36. But even if White hits the shot, the win isn't guaranteed, because of White's 5pt gap and Blue's race lead and good board. On the flip side of the coin, if Blue doesn't leave a shot right away, the game isn't gin; however, White's chances are pretty poor in these variations. I'd drop here. D/P.
