Can O take? Two checkers on the bar against a five-point board, with a
third blot vulnerable to being hit as well, looks like a pretty dire predicament. But X may have some difficulty leaping his back checkers
over O's prime before he is forced to crunch his board. The rollout
below says it's a pass, but just barely. Shifting X's spare on his
3pt to his 2pt causes XG to take (see variant below).
