Whites game by move 8 is set up to try to pound on the castled king. Long castle for black is better, that light bishop can linger on the board for the entire game, pointed at the king and deadly. I would have taken it pronto on move 8. White should not have allowed this, since it is a key piece in the position, Nd5 prevents you from taking it, consider what you would have done after Nd5 carefully. (Na5 is a popular black response in these positions).
14) g5. I am just not a fan of using your king's defensive pawns to chase an elusive bishop. You can't trap/catch it, all you are doign is let your opponent bait you into "often" bad pawn moves. It can be handy to push those pawns, but it can also leave you with a defenseless king ...
19) Qg6 and your following moves are what really cost you the game, though. One fast and loose rule of thumb is "avoid self pinning". QXQ instead of RXR would have left you in a drawish position, or possibly even a way to turn it around and win, but RXR was suicide. After you lose your queen --- look at the board. Your bishop is trapped and can do little. Your rook is out of position. Your king is exposed. You are way behind in material. It is *done*.
After QXQ, any of the other combinations should leave R&B vs. R&B and endgame/tactics/pawns will decide the game in the distant murky future, but eyeballing it seems drawn given excellent play by both sides and no time problems etc...
So I was wondering if you guys could show me where i went wrong with this game. I had a great position with the Scotch Game but lost it all. Thanks.
