Well, this is a game I once played in a small local tournament years ago. It's something I remember up to now because I managed to beat someone better than me, because I thought he underestimated me. The opening was the queen's pawn, and I had the black pieces. It went like this:
1. d4 d5
2. c4 e6
3. Nc3 Nf6
4. Bg5 Nd7
OK... Now I'm going to try to work out this so-called FEN for the first time. Here goes...
OK... I hope I get it correct. Now the question: If you're white what's your move, and what are your reason(s) for such move? Don't cheat; don't search from database or consult computer analysis. It is interesting.
