Knigh E7 takes on rook c6 check mate automatically on the next move cuz if queen d5 take back the knight then it’s a check mate with queen a4 take queen c6 no where to go for the king or if instead queen don’t take back the knight then rook f3 move to e3 protected by the bishop g1 and check mate king can’t move no where them two options are both check mate in two moves
