Just posted this in another forum. Villain never did explain his thinking, but really, were words necessary?
Just when I thought I'd seen everything...
1/3 NL, $335 effective stacks, it's folded to me in the CO so I raise the mighty 3

and get called by the BB.
Flop A

because I've been working hard on flopping the world on blind steals. He checks, I bet $20.
He check/minraises to $40.
I have a feeling this is a "where am I at? raise", so I tell him by 3betting to another $110 on top.
I have $170 left, so he, of course, 4bet minraises again to another $110 on top.
Well, the gig is up, but I shove the rest of my chips in and hope that it's a coin flip and that I win.
And he...
Tanks. The pot is $610, it's $60 for him to call my 5bet, and he's in the tank. He tanks for 2 full minutes before finally... folding.
Awesome. The ol' 4bet/fold play (with two minraises at that). I show the 3

for fun.
