29...Rf2+?. Black lets the win get away. 29...Bxh3+ or 29...Nxd2 wins easily. 30.Qxf2 Nxf2. Kasparov: 'Both players had only five minutes left. Thank goodness for intuition! Some sixth sense made me reject the obvious 30...Bxh3+.' If 30...Bxh3+? 31.Kg1 Nxf2 32.Ra2 Qb3 (32...Qf5 33.Ra8+ and Black must accept perpetual check) 33.Ra8+ Kg7 34.Ra7+ Kf6 (Not 34...Kf8 35.Bh6+ mates) 35.Nf3 Nd3 allows mate by 36.Ne4+.
31.Ra2 Qf5. 31...Bxh3+ 32.Kg1 Qb3 is the same as the previous note. 32.Nxd7 Nd3.
