Money Play. How should Red play 21?
The key when playing against a potential back game is to deny your opponent a second anchor if at all possible.
Here Red is no danger on White’s side of the board so making the 20-pt is irrelevant. After entering with bar/24, he must use the 2 to hit with 6/4*. Any other move is at least a bad error.
