1... Rexg2+ Most players would probably select 1... Rgxg2+ 2. Kh1 Rh2+ 3. Qxh2 Qf3+ 4. Kg1 Rxh2 5. Kxh2 Qxd1 6. Rc7 Kg6 with a win. But, this is not the fastest path to victory. 2. Kh1 Rh2+ 3. Kxh2 In the actual game, white chose 3. Qxh2 Qf3+ and now white resigns with mate on the next move. 3... Qxa2+ and mate on g2 is unstoppable. 0-1 [J Todhunter]
