Match Play. Red leads 3-0 to 7. How should Red play 42?

Red cannot play passively here. He needs to contain White’s checker and also escape his rear checker.

10/8, 10/6 is hoping for too much to go right. Red must slot the 4-pt with 8/6, 8/4 and hope to cover the blot next time.

Any other move is at least a double blunder.
