The difference is after 11...Rf6. White can mate one move earlier with: 12.Bh3 Rxf2 13.Be6 Rf5 14.Bxf5 h3 15.Be4# The ONLY question that I found regarding the whole line is with Black's first reply. Chessmaster was not able to quickly find a mate for White if Black plays 1...Rd7, leading to this position. Can anybody else find a forced mate for White here?
