MissedPlayed b6b7(lost a forced mate)Claims true 0%858 out · $0.0092 · 11.6s

Stated plan

Push the pawn to b7, attacking the rook and threatening promotion.

Resolves to b6b7 · lost a forced mate

Reasoning

The b6 pawn can advance to b7, forking the rook on c8 (attacking it) and threatening to promote on b8. Black cannot both save the rook and stop promotion, since any queen tricks with Qb1+ are simply met by Kxb1.
