I don't know why I raised preflop. Maybe I wanted the blinds. Maybe I wanted to change my image at the table. Maybe I was on tilt. Maybe they had been folding all their blinds to me. That's not the reason I'm posting this. I wanna know what you think about the rest of the hand.

I raised on the flop because his bet shows weakness and because of how he had been playing earlier I thought he was drawing to a flush once he made the call.
Since he missed the flush on the turn. I bet into him again, so that my bet on the river wouldn't look like a steal.
On the river I make a small bet into him that he'll fold to if he was flush drawing.

It's quite a poor hand but there were some reads involved and that is why I continued to bet after the flop.

I made a similar post to this a couple of weeks ago where I bet into a few flush draws. Making a small bet into a flush draw on the river is quite a new play for me.

What do you think about the bet on the river?

Thanks.
BTW, I don't need a whole bunch of insults thrown at me. I see how bad I played.
