i start off the hand in the BB with AKs(hearts) in a 6max game i'm in the BB it folds to the button who opens 5x the BB 0,25 SB folds to me i 3Bet him 0,75 he cold calls.
Pot:1.5eu Hero:AKs(hearts)
Flop:5hQh2s
i decide to bet small with the nut flush draw 0,35c he calls.
The Turn:9h
i decide to check here he checks back
River:Q of spades
and i decided to shove and got snap called with Q10o.
so what i wanted to know here is it a mixed strategy on the turn where we check our nut flush or do we have to absolutely bet it and if so we bet it whats the sizing for it? do we bet half pot or donk it?
and in the river should we care if the boards pairs and check it back and just call as villain could have called with 55/22 pre(im playing vs tards) if i take into account villain is a bad player and could have called with 55 and 22 pre when the river pairs the board (i know i'm not really playing optimal but you gotta start somewhere) do we deviate from an optimal strategy ?
and can somebody tell me whats the gto line that shouldve been taken with AKs in this spot would be much appreciated. :D

hey everyone i'm new here i wanted to have you guys opinion on a hand i played today which has left me abit confused.
so i was playing with some friends you could say NL2 (in my country currency LUL) i'm UTG+1 got JJ i 3bet guy on the SB calls.
Flop comes T97r he bets a little bit than half pot,i check raise he calls, turn comes a deuce basically a blank and by then i know he is on some kind gutshot or sd like A8,K8,Q8 65s so i decide to shove on the turn to deny him the odds of his draws and since i'm blocking the nuts with JJ..
he tanks then calls me with A8s and hits the A on the river.
so obviously after the hand i just quit cause i'm tilted to whole new levels because 1/i dont know if i played correctly or not 2/if i'm playing vs a donk 3/im fucking bad and my line doesnt make any sense at all.
could someone tell me whats the gto line here that couldve been taken on flop & turn ? and thanks i'm a fairly new player
