I've got you on A,7 and UTG on something like J,10 clubs or J,Q of clubs. I can't see UTG having a big hand (pocket A's or Q's) and checking that flop, and I can't see how you have a big hand and don't re-raise pre-flop with all those limpers.

I think UTG checks on the flop planning on the check-raise with his 4 to the flush, but since it gets checked around he doesn't get the chance.

He knows you don't turn the straight because you would need to re-raise to protect against the flush draw.

The river gives you A's up, and you're pretty sure he has a busted flush draw with either a medium pair or a lesser two pair than you.

You don't push with just a pair of A's because the only way you get called is if you're beat.

I think there is a slim chance UTG has AJ or AQ but if so he made a mistake not betting the flop.
