UTG is a fairly knowledgeable player who overvalues 2pair and is willing to get into pissing matches with good hands.

Also he's spewy with draws with a "Gambooool" mentality. Willing to 4-bet HU with a Flush draw even though he knows I don't 4-bet unless I'm pretty certain I'm ahead.

Preflop: Hero is MP with A, A.
UTG raises, Hero calls, 3 folds.

Flop: (5.40 SB) 7, J, 5 (2 players)
UTG bets, Hero calls.

Turn: (3.70 BB) 8 (2 players)
UTG bets, Hero raises, UTG 3-bets, Hero caps, UTG calls.

River: (14.70 BB) 4 (2 players)
UTG bets, Hero raises, UTG 3-bets, Hero caps, UTG calls.

Final Pot: 25.70 BB

So I guess the question is, at any point during the turn and river raise war... was I spewing?
