I Screwed Up My BackGame Defense Checker Play

I am posting nine positions, all from the same game against my good friend and sparring partner Kenji. The total amount of equity I gave up in these nine plays was well over .8, if you believe the XG evals. I realize that it would be better to do 4ply rollouts, but I will, at best, present 3ply rollout results.

Tougher to play the checkers when defending against a backgame than when offending a backgame. Anyone who makes the best play in just one of these nine positions is much stronger at back game checker play than I am.

Position 1.
