I'd continue.
...to draw or not to draw...?

Its a draw if black plays well. You need 4 moves to deliver mate with a Knight, and it will take at most 3 for the Black Queen to reach the White King.

I agree, Black can never win, so always let him prove it's a draw. Those passed pawns look dangerous, so I suspect it's won for White anyway.

According to rybka this position is 100% drawn
So since when is that a reason to offer a draw? Let him prove it.
Since Black's pawns are all blocked up, and his King can't move, you effectively have three pawns, a King, and two Knights vs a Queen. That should certainly be enough to win. If it's a draw, then let Black prove it. If not, then you have the best chance to win.

how is it UNFAIR ?
I thought this was a game in progress and it would be unfair to give one side tips. If it's not a game in progress then disregard what I said about fairness.
I was actually thinking about this game during lunch and decided I would keep playing with either color, if only long enough to make the other side prove they knew what to do.
OFFER A DRAW OR CONTINUE?? (for white)
