Villain is a TAG reg.

The raise size is notesworthy. I think opponent's range is stronger than usual, because I've occasionally seen him limp/calling 77. I would put his range to open and call at something like JJ-TT, 88, AdAh, AdAs, AdAc, KdKh, KdKs, KdKc, QdQh, QdQs, QdQc, 9d9s, 9d9c, 9s9c, 7d7h, 7d7c, 7h7c, AQs, KQs, QJs, AhKh, AhKd, AsKd, AcKd, AdQh, AdQs, AdQc, AhQd, AsQd, AcQd

My 3-bet range is something like TT+, 88, 9d9s, 9d9c, 9s9c, 7d7h, 7d7c, 7h7c, AJs+, A5s, KQs, QJs, AKo, AdQc, AhQc, AsQc, AcQd, AcQh, AcQs

Equilab shows that I don't have a range advantage here. I could bet big or check here. I elect to check/call. His bet is fairly big; he is representing an overpair or a set.

When the turn checks through, I estimate that he mostly has pocket pairs here, and likely does not have a set. Also, he could have some some Ace highs that are giving up or trying to showdown.

River is a brick. I only have a bit more than pot-sized bet left. So I jam. I can stack overpairs.
