V - 50s white guy. Regular who plays a ton of poker. This is the first time I've played with him. Been playing about 4 hours before this hand takes place. Overall, he seems to be a winning TAG though his game has minor holes like raising too small pre-flop. He's been very active from the button and CO. He likes to open a lot of pots from co and button and he'll call pf raises more liberally than most tags, but only from the button. He's fit or fold for the most part when he cold calls raises. He called two of my ep raises on the button previously and had just folded to my c-bet. He's aggressive post flop, but has only flipped over strong winning hands at showdown. He hasn't 3 bet a pot pf yet. Maybe he just hasn't had 3 betting hands or maybe he just likes to flat with them. I'm sure he has observed hero's super tight play pf and watched hero stack a few guys. Hero has been c-betting probably 80% of the time.
Hero is racking up his chips and has two hands left to play when:
Hero ($480) opens to $15 from UTG+2 with Q
Q
Folds to V ($230) who flats on the button
Flop ($29)
6
4
2
Hero bets $20
V min raises
Hero re-raises $100
V goes all-in for $175
Hero tanks. On one hand, I'm getting ridiculous pot odds to call. On the other hand, I can't see myself possibly having the best hand. This is the first hand all day I had 3 bet on the flop. He had to have put me on a big pair after my flop 3 bet. Also, V's behavior changed dramatically. After being focused on the game completely all day, he all of a sudden was interested in other things while I was thinking (television, waitresses, etc). He looked everywhere except at the table.
I put Vs range as JJ, KK, AA, and sets for sure. There's a smaller chance he could have had 2 pair or a straight. 0% chance of a bluff.
In my self analysis, I have two doubts. One is the size of my 3 bet. The other is my planning. I'm not sure I thought enough about what I was going to do if he shoved. It seems maybe I should have bet a smaller amount to give myself some wiggle room if he shoves.
This hand is bugging the living **** out of me. I'd appreciate any feedback.
