No way you're checking behind there. Maybe not going all in, but you're not checking behind on the river. Make a value bet, and if someone raises, call.

You want to make a bet small enough so that TP will still call. IF they raise you, they might have two pair or just REALLY like their top pair; either way, you should call.

But set over set...life just sucks when that happens if you ahve the lower set.
