Match Play. Red trails 7-9 to 11. How should Red play 51?
Never give up your anchor! Where have I heard that before?
There is plenty of time to resolve the issue of the back checkers later. For now, Red should concentrate on blitzing/priming White.
Clearly correct is 8/7, 8/3. Running out with 201/15, 8/7 is premature and a bad blunder.
