Rajkumar (white) played effectively and should be congratulated for his effort. Ton-Chung made an error when she played 6…Bxf2+ thinking, perhaps, black could have won a pawn and prevented her opponent’s king from castling. The combination backfired when black realized her queen knight was en prise. White played sharply with the move 14. Nd5!, which demonstrated the beginning of a successful combination.
