Where did I go wrong??
This game was interesting because:
1. He played the Scotch-something I am not familiar with
2. During the game, his rating went from about 1510 to 1886.
3. I was too friendly with this guy and hinted that I had some tactical shots (which he admitted he used to his advantage).
He beat me quite convincingly Nevertheless, excellent play by my opponent!
Any ideas on how to improve my play in this game?
