Ke2 Rc2+ {Knight Moves  White is clearly winning, but must react to the check.
Please work out for yourself first, if 67.Rd2 wins or not, and try to
calculate to the end. Springertaktik  Weiß steht klar auf Gewinn, muss aber
natürlich erst auf das Schach reagieren. Versuchen Sie bitte zuerst selbst zu
klären, ob 67.Td2 gewinnt, bevor Sie weiterlesen.} 67. Rd2 {Yaparathne had to
calculate far ahead as his king leaves the square. Yaparathne musste weit
vorausrechnen, weil sein König das Quadrat verlässt.} (67. Kf3 h3 68. gxh3 g2
