Move 8. Bf4 seems like it was a wasted tempo since you had to move it again to Bg5.

Move 16. It would be neat to see Kg2 and try coming in through the open file. Not sure how it'd work out, but an idea.

Move 21. Nh5+ might have been really interesting. Force Bishop off with a decent attacking position with use of that open file. Another opportunity at move 22 I believe.

I don't know endgame well enough to see any corrections in there.

wow

Shane97,piotr  is  white.

witch color are you?

from there i'd move "49. g6" and try to promote. Eventually you would promote but that's just my opinion with tiny little 1125 rating i can't touch a master like you guy's so that's probly a bad move

 After  24....bd4, you removed the king to free the Knight from the pin, however, the Knight is lost either way. 

 If you had played 25. Qxg5 +, you will win a pawn and either he blocks with the bishop, blocks and trades with the queen.  Or, the very bad idea of  25...Kf7, 26. Rh7 +, skewering the king and queen, winning the queen.
