I opted to attack here with 7/3*(2), but XG says that's a massive
blunder. X is still a bit behind in the pip count after this roll,
and a surer way to win the game is to make the five-prime. It's
true that attempting to blitz with 8/3(2) 7/3*(2) will win more
gammons, but it won't be that many gammons because most of O's
checkers are already home or nearly home. O will likely have
multiple chances to scramble home the last checker, and loose hits
will be dangerous because of O's strong board.

Leaving the opponent behind a prime that he can only escape with 6-1 is a very strong formation. Most of these positions result in double/pass.
