Just because a pawn looks so small...

...it doesn't mean that they aren't capable of doing serious damage!!
(PLEASE NOTE that the diagram below is NOT the real diagram. There were two opposite-colour pawns on the same file and I also had a knight)

So I'm playing this game as white and I win. But, in this position, it was black's move and he does something sensible (sensible, as in, not a downright blunder). But then a spectator yells out, "Why didn't you do ...Ng4+?! It forks the king and pawn!... oh, yeah... er..."

Lesson to be learned:
PAWNS ALWAYS MOVE AWAY FROM ITS STARTING SQUARE...

UPDATE 06/05/2011: Just played a blitz game as black... almost let go of a bishop when it could've been taken by a white pawn... got used to playing as white!!! Oh dear...
