Throughout the game, I thought I had a positional and piece advantage, but I STILL LOST!
What did I do wrong? (using Ruy Lopez btw)
[FEN ""] 1. e4 e5 2. Nf3 Nc6 3. Bb5 Nf6 4. Nc3 a6 5. Bxc6 dxc6 6. O-O Nxe4 7. Nxe4 Bg4 8. h3 Bh5 9. g4 Bg6 10. Nc3 Qd6 11. Re1 O-O-O 12. Ne5 f6 13. Ng6 hxg6 14. d4 Rxh3 15. Kf1 Rh1 16. Kg2 Qh2 17. Kf3 Qh3 18. Ke2 Re8 19. Kd2 Re8xe1 20. Qxe1 Rxe1 21. Kxe1 Qg4 22. Be3 Bb4
At this point, I surrendered because I'm at a positional disadvantage, my knight is pinned and my rook is still undeveloped.
I know one weakness of using Ruy Lopez is that your left side develops slowly, but damn! Where did I make a mistake? Was I just unlucky?
EDIT 1: OMG I just realized he baited my king-side pawns to open up for an attack! >:(
