Plain and simple, this is a +$EV push, not just a +cEV push. You and him are about even, which is even more of a reason to push IMO. Fold here and you give him another chance to take the lead. This push only becomes -$EV if you think he will call with more than 40% (22+,A2+,K2+,Q9o+,Q5s+,JTo,J8s+,T9s) of hands, which is more likely to happen at the next blind level when half his stack is in the blinds. As it is he's still got what, like 4BB left if he folds?
