Hi everyone,

I would love to hear how people judge their 4 bet sizing preflop. I have an example below and would love to hear if my sizing is too big and that is why he folded. Do you normally 4 bet your aces or do you just smooth call a 3 bet and trap with it?

PokerStars - $0.50 NL - Holdem - 9 players
Hand converted by PokerTracker 4: http://www.pokertracker.com

BTN: $112.69
SB: $107.78
BB: $51.59
UTG: $50.75
UTG+1: $50.00
MP: $69.76
MP+1: $52.00
MP+2: $50.00
Hero (CO): $60.49

SB posts SB $0.25, BB posts BB $0.50

Pre Flop: (pot: $0.75) Hero has Ad Ac
fold, fold, MP calls $0.50, fold, fold, Hero raises to $1.50, BTN raises to $5.75, fold, fold, fold, Hero raises to $15.00, fold

Hero wins $12.75

Is my sizing too big? Plus with everyone else folded it would just be heads up with CO, so should I just smooth call his 3bet and go heads up or was this 4 bet the right play?
