I think I'd opt for the push in this spot. If you had a deep stack then a check to keep the pot small and decision on the river would be called for. But as it stands if you check you are going to induce a bet on the river card most of the time I think. Then you have to make a calling decision, you have taked the lead from the start of the hand no reason to stop now.

I'd push my $123 in and hope for the best. He may lay down a str8 wrap like yourse or top 2.
