I suspect this is a forced draw no matter whose move it is, and I'm pretty darn certain you're not going to win, so the question is do you accept an immediate draw or do you take a risk you might actually lose?
You have less material, your king is less active, you have zero prospect of breaking through or otherwise getting a passed pawn. In other words, I don't see how you can possibly win.
I'm not sure how you could lose either -I think you can trade all the pawns and end up with K vs K + N, which is a draw. I think I'd play a while longer, just because I obviously need the practice with this sort of scenario.
I played black in this game. Should I have accepted a draw?
