so
not enough power!!!

i thought things were going to turn my way after 26...Qxa3+ this is where im at a loss for what i could do next
22. ... b5 looks better than ... f5. Although you did play it by move 25, you had already moved a rook away weakening your attack.
33. ... Rb8 looks better than ... Re8. The white queen can't take e5 because of Rxd5+.

i didn't understand
46... Ke7.
now that we can see what he was after, it is easy to say that
46... e4 or ... Bf1
would have been better. you still wouldn't have had much of a chance with a bishop v. rook, but you could have at least gotten up a pawn and maybe graduated.
thanks for looking!!
ps... the end of the game fell apart for me, playing chess first thing in the morning (while severely hung over) is not a good idea!!! so please disregard the knight fork that i fell for tward the end of the game.. thanks :)
