Garry Kasparov announced a
                               forced mate in 25 moves (!) after
                               62.....Qc6+ 63. Kg5. An emphatic way
                               to conclude the game. The main line runs:

                               63.....Qd5+
                               64.Qf5 Qg2+   (64...Qd8 65.Kh6 is mate
                               in 22)
                               65.Qg4 Qd5+
                               66.Kh4! Qg8
                               (instead if 66...Qh1+ 67.Kg3 Qe1+
                               68.Kf4 Qd2+ 69.Kf5 Qc2+ 70.Kg5
                               Qc5+ 71.Kh4 d3 72.g8(Q) Qf2+
                               73.Qg3 Qf6+ 74.Kg4 Qd4+ 75.Kh3
                               Kb2 76.Qg2+ Kc1 77.Qh1+ Kd2
                               78.Qa2+ Ke3 79.Qe1+ Kf4 80.Qf7+
                               Kg5 81.Qd2+ Qe3+82.Qxe3 mate)
                               67.Qf4+ Kc2
                               68.Qf8 Qh7+
                               69.Kg5 Qh2
                               70.g8(Q) Qg3+
                               71.Kf5 Qf3+
                               72.Ke6 Qb3+
                               73.Kd6 Qb4+
                               74.Ke5 Qe1+
                               75.Kxd4
                               now it's mate in 12. For example:
                               75....Qa1+ 76.Ke4 Qa4+ 77.Ke3 Qa7+
                               78.Kf3 Qb7+ 79.Kg3 Qc7+ 80.Qf4
                               Qxf4+ 81.Kxf4 Kd3 82.Qb3+ Kd4
                               83.Qb5 Kc3 84.Ke3 Kc2 85.Qb4 Kc1
                               86.Kd3 Kd1 87.Qd2
                               mate

                               If Black deviates from this line, then
                               checkmate arrives even sooner. A very
                               "computery" variation!
