My opponent had scored 7 points out of 7 games (both county and national team championships) this season, so I was surprised to see his setup during the game. I was constantly expecting him to make some splendid move that would suddenly alter the course of events, but all at once with a lonely knight against four pawns on the board he stretched out the right hand...so I think I somehow (somewhere) missed it.
