Bobail Analysis

Squares are named as in chess, by column, a to e from the left, and row, 1 to 5 from the bottom, as White sees the board: White's home row is row 1 and Black's row 5. ⇅ Flip turns the board round, to see it as Black does. Each turn is two moves, the bobail and then a piece, except White's first, which is just a piece. A move of the bobail, marked , is written as where it goes, c2; a move of a piece as where it starts and where it slides to, a1-a4. A percentage is the chance the player to move wins, as the computer reckons it from the games it plays out. WIN and LOSS are certain: forced win in 5 means the game is won within 5 moves, counting this one and every move of the bobail and of a piece, whatever the other player does, and the line shows how. The move shown on the board is the blue arrow. Click a move in a line to play the line out to there; point at a line to see its first move on the board.
