A small sample on opponent: 51/0/3.4/29/41 [VPIP/PRF/AF/WSD/Hands]
Flop: My top pair got hard reaction from my opponent, Check/Raise. I realized his Raise is quite small, but cannot be underestimate here. Perharps he's hit a set with 55, 44 or two pairs with K4, K5 (his range is quite wider) here. Though my hand's Equity is very small to beat his hand (as I assumed), but I still called his Raise, because his Raise is small, I've got a top pair with medium kicker, and maybe back-door FD.
Turn: He shows his aggression. I have nothing more than implied pot odds, and hope Turn card will complete my FD.
I realized that I made mistake on Flop when he was Check/Raise like that, but is that profitable to call his small Raise with those what I have with my hand (TP with medium kicker, a backdoor FD)?
You should CB ~$0,18 at least. Although as played overall seems to be fine. But obviously should fix your bet sizing.
