how to maximise against BTN open range??

Had not been on the table for very long, as such no specific reads on villian.

My question is this: how can i extract maximum value from villian's wide range here, assuming standard open raise range from the button?

i feel i got close to the maximum from his specific hand, but in terms of his range i feel the hand could have been played a loooot better?

didnt bet the turn for fear of folding out majority of his holdings, especially if he is going to double barrel which seems plausible..

anyone raise flop of let him bet turn again??

and yes i think river bet is too small

Why are you checking????

bet/bet/bet readless every time.

no idea why you're checking this down; bet flop and turn with a wide range.

lol yeah it's all pretty bad I agree..
at the time I just felt like I was crushing him and betting the flop would fold most of his hands (I guess overly eager to get paid off) check flop as if to say "well I thought u were stealing but u called, so dam"..(rediculous?) turn I see must be bet..
to squeeze $90 out of him with A7o wasn't so bad but poorly played hand I agree
