I tanked realizing I had bet too much to bet/fold.

I eventually called and he showed me KQo. I don't think I've ever seen a lead river/3bet ship as a bluff before. I felt like I should've folded as even new players can usually recognize if there's a hand out there that beats them (i.e. lots of rec players might just call my raise with K9 or 99 here.

Why do you think so? There's almost zero chance that it's the best hand pre-flop. Everyone says that if the pot is multi-way that they're getting great odds to call so they should call with a weaker range. But that's not true. In a very multi-way pot, the winning hand is going to be very strong compared to a heads-up pot.

This whole thread is just so weird.

People claiming that the Villain is raising K2 on the river hoping to get called by what, someone who was dealt a king and not a second card? And then they're supposedly calling a shove with that K2.

There's zillions of people who always claim that every spot is a Must Bet; checking is a huge mistake. But in this spot supposedly the Villain is betting a huge range of hands and willing to call a shove with them.

I still believe that the Villain's donk on the river indicated a hand that he thought was likely ahead of our calling range. If so, JT is the weakest hand that he should have bet.

I'm still wondering whether Havax was lucky and the Villain showed up with K2s.

Edit: I see the Villain played his hand totally face-up. By face-up I mean he wasn't betting a hand that was behind our likely calling range. He was betting a hand that was ahead. He wasn't stacking off with K2s hoping to get called by QJo.

Agreed - this fits exactly with what I see against my current primary player pool.
