Rim gambit game 6 (no result, 110 plies)

The Riverbank Cannon

57 moves

Misty against itself, with Red forced through the rim gambit: cannon to b5, then a5, chariot taken. The grab landed in all ten games, so every one is the guessed-wrong branch played out by equal engines. The landed cannon sits on the pin or slides out; it never donates itself.
