another chess post - can i win this?

[SCfuji]

ive been practicing more and i came upon this situation. we went back and forth in material (erik took a pawn early but i actually recovered and was ahead 2 points because i had an extra knight but had one less pawn. then i had to sack the knight but i ended up getting that extra pawn so we are even now. im kinda stuck here. erik said that it was impossible for me to win this. it is my move, any winning combos (given that my opponent played perfectly)?

thanks
