5...f6 is the book move but Bg4 is fine
you played the opening pretty well
I would have played 10...Nf6 or Bd6 or Kb8
you really needed to develope you kingside before pushing b5 and c5 and c4. After 13. ...bxc4 white had the edge, but he didn't play all that well after that and then dropped a piece.
overall good game
This is the first game that I have played somone who opened up the ruy lopez.. I didn't know what to do but I did what I could and still managed the win, however, I was a little afraid because my opponent had only lost 1 game and I was not prepared for this. Does anyone know where I can fin
d moves to counter an open?
