To Qualify or not.

This game is about qualifying for the next round of a theme tournament (Ruy Lopez) by Chess.com. In this final game, a drawn game is enough to qualify me for the next round since I have a higher tie-break points in case we have a tie at the top with one of the players,Laser. In the beginning I have no intention of drawing the game but as the game went into the final stretch my mind change from winning to just drawing it. I know I did something wrong along the way, and please help me pinpoint my mistakes. The game is against Maciek (1979) playing white and I am handling the black pieces.

good game

Yeah tonydal you're right the position was really close but winning. But a draw is enough to get me qualified. so I don't wanna risk it! Thanks for your comment guys!

nice game i think your 42 move Nh5+may be you have advantage

i think 42 fxe3 should be crushing

Yeah, shrinivashan, ... Nh5+ should be the key move! Maybe the pressure was just to much on me that I was just merely playing for a draw. Moral lesson is; "too much ruins your game." Thanks guys for your additional comments!
