Spotting Tactical Threats
Seirawan Strategy Example #2
Winning Chess Strategies, Diagram 11, p35
This example is a warning about not taking the remainder of your game seriously, when you're in a winning position!
The unnamed girls in question played in a tournament that Yasser Seirawan observed. The girl controlling Black's army had a winning advantage (note the Passed h2-Pawn one square away from Promotion).
The girl controlling White's army was losing and, according to Seirawan, decided not to resign but use her pieces to check Black's King, just for the heck of it.
Black's mistake came when not concentrating and thinking of being crowned the World Junior Champion. The Piece she moved enabled White to Checkmate her opponent one move later! For the full story, turn to pages 35-36 of Winning Chess Strategies.
