You are putting a ton of money into the pot with a mediocre hand. I understand that you're bluffing but I would need more than stats to make this play, even with high confidence in them.

As far as hand-reading, some people do cold-call 3 bets with KQs, KJs, KTs, QJs, QTs, AK, AQ, or TT. I wouldn't put any of them past this villian. Part of the reason I don't like this play is that you still don't know where he is after the turn 3 bet, which of course is why the read is difficult. He could have a K, QJ, or is just getting stubborn with a T. Most likely you are spewing hard.

BTW I don't want you at my table.

PS Since you are soliciting hand reads I'm guessing villian made a pair of 7s on the river.
