I agree with fim, I don't mind the play. To reraise the flop would basically mean you're commiting yourself to this hand since Villain only has about $50 left. So to reraise him, you're basically putting him all in. He may actually call, who knows, but most the time if he calls for the rest of the stack, you're beat. I like the idea of just becoming passive and letting him bet away witht the worst hand. I like that anyway better than putting him all in after the flop without that much information on his hand.
