 | | Pawns may suddenly appear on the seventh rank and promote to queen on their next move, checkmates may be accomplished via an overwhelming combination of pieces, etc. A win is accomplished by checkmating first on either board, or by winning on time (one of the opponent's flags falls first). |
 | | Insufficient mating material is generally considered to include a lone king, a king and a bishop, a king and a knight, or, in most cases, a king and two knights. |
 | | Two knights may constitute sufficient mating material in situations where the defending side has at least one pawn, or where there is a forced mate on the board; otherwise the position is likely to be a draw either via stalemate, three-move repetition of position or the 50-move rule. |
