This hand happened in the mega Sunday Million recently. Flop and turn are standard, the tricky part is the river. I would expect villain to 3bet JJ+ for sure, probably TT+, and I block 99 which would be his best flatting overpair. He can't have many 7x combos: only 2 combos of 76s and 2 combos of 87s. I also block 88, and the board pairing leaves only 4 combos of 77 and 55. I don't see him showing up with 64s or 69s. I don't block hearts of course, but his bet sizing is super polarizing, and there are plenty of bricked draws he could have like 9Ts, JTs, and J9s, most of which I don't block. Plus he knows I'm capped, so it would be a perfect board to put max pressure on me. Then again, it's pretty early in the SM, so I don't know how likely a huge bluff is at this stage. Thoughts?
