It’s a massive pot to play at this stack depth, but I still expect villain to have some bluffs here. I don’t expect sets to be going for stacks without a heart blocker (I may be wrong), which leaves the one combo of KK and whatever suited hands villain 3bets MP vs UTG.

The Ah seems like a double-edged sword. We obviously block the nuts, which significantly lowers flush combos, but we’re also preventing all of the villain’s most natural bluffs. This seems like a better hand to call with than TT or 66…

Ugh, this one has me all tied-up in knots.
