Learning NLHE #1: Facing a check/raise in 3bet pot holding TPGK

Posted 7 years, 11 months ago

Blinds: $0.02/$0.05 (6 Players) BN: $18.00
SB: $6.52
BB: $7.60
UTG: $5.18
MP: $6.30
CO: $6.02 (Hero)

Preflop ($0.07) Hero is CO with Q A

UTG folds, MP raises to $0.15, Hero raises to $0.52, 3 folds, MP calls $0.37

Flop ($1.11) A 4 8

MP checks, Hero bets $0.65, MP raises to $5.78 and is all in

Could my cbet sizing be optimized?

I am not sure what to make out of this check/raise. Could be AK, could be a flushdraw, could be a weaker ace.
Do you call here vs unknown?
