I was going to insta-push, but then I wasn't so sure. No read whatsoever on the second chip leader since I've been multitabling, but his large chip stack and his flat call against the short stack got me thinking. Does villain have a marginal hand here most of the time to make a push profitable, or does he likely have a monster. Is it worth my decent stack at this stage in the tournament to find out? I'm thinking calling is best, thoughts?
