I want some advice or complain what i done wrong about this board and i will give the result after that

Why check the flop?

Last thing we want is to be passive on a connected board. Plus we dont make money by checking

+1 what @Aces says. There is no reason not to do CB.

As played, seems fine turn and river. Raising seems over optimistic, so call turn, call or fold river. I don’t think river decision is so crucial. Sometimes you win sometimes lose. Mostly you lose, but you have to be right one third, and it’s going to be close, probably it’s a bit –EV (by feeling, no analysis)

thank all like u said i should bet on flop becuase my villain got staight with a9o

You should bet because you bet for value. Doesn't matter what villain has, because you don't know what he has.

this board very drawing, so checking the flop not good idea, don't let free card for villains. u must bet for value and protect your hand.

1. CB most of the time and 60% of pot on flop.
2. CB not only protects your hand, it builds the pot. You can't assume opponents will build pot for you. Occasionally they will...
3. Turn and River play are fine.
4. Value town this guy from here on out...
