Main villain is a little bit spewy/stationy and aggressive. Two hands played against the same guy from the same positions in a single session:

Hand 1:
600 effective 2/5.

Preflop (7):
CO limps
Main Villain on BU raises to 20
Hero 3-bets to 75 with AcAs from SB
BU Calls

Flop (160): Jc7c2c
Hero bets 20
BU calls

Turn (200): 4d
Hero bets 110
BU calls

River (420): 3h
Hero?


Hand 2: I'm going to give this hand history from Villain's perspective because I think it will make for a more interesting discussion. I am the SB in this hand.
650 effective 2/5.

Preflop(7):
Hero on BU opens 15 with QTss
Villain in SB 3-bets to 60
BU calls

Flop(125): Qh9h3h
SB bets 15
Hero calls

Turn (155): 5s
SB checks
Hero?

I don't like your pre flop sizes in either hand. I assume #1 is exploitatively small in order to try and get a call. I'd go $100 in hand one and #75 in hand two.

I guess I've never heard of using sizing this small before. I'd go 1/3 in both spots, but I'm curious to hear about the sizes you used.

I have no idea what the turn card in hand two is, but I like the size you used in hand one.

I'm conflicted between bet-folding $125 hand one and shoving. I would probably go $125 because he probably 4 bets KK pre flop and so the only worse hand that I am confident is calling a shove is QQ. I feel like Jx and 88-TT may fold to a shove, but will call $125.

Hand1:
I like bigger on flop, but still small. Something like $35-$40. Turn sizing seems fine. I think river is a shove because your Ac weights Villain more towards one-pair bluff catchers, and you'll also be shoving this river yourself with hands like AcKx, AcQx.

If we check, it's to call any bet, and I'm not convinced V will be bluffing often enough since we block the main bluff card in Ac.

BTW, a shove becomes more natural when we bet slightly bigger on flop. $35-$125 on flop-turn would make the pot $500 on the river with $375 behind.

Hand2:
Probably checking back any card except a Q or a T. If a heart falls, maybe you could consider turning your hand into a bluff.

sry, turn card in hand 2 was 5s

I don't see why we would ever bet here with QT but maybe I'm missing something

H1: I'd go $40 flop, then 2/3 PSB turn.
As played, we have < PSB vs. an opponent who has some aggression, so If behind, we likely would have heard by now.
I lean toward a jam >> X. Columbo post nicely states why.

H2: A bit thin, but I like a small bet of $60 for value. Targeting JJ/TT/over cards with a heart, maybe 15ish total combos.
