Hmm - dunno why the results didn't show. Here's a repost, with results... I agree with you, but what's the alternative play? It seemed to me that I couldn't be scared of the queen when I hit second pair. By the same token, if I was only going to bet half my stack, I supposed I should have been willing to fold. It didn't seem like there was an easy way to handle this situation.
