V is reg, dont steal much on FT so I decide to flat becouse hate to 3bet fold in this spot, dry board so I decide to raise and sizing is to small 17-18k would be better, turn is ok, I must call river never see myself folding. Give me some thoughts on the hand.

shove pre. as played, don mind r/get in otf.

its shove or fold pre, we cant flat or sized 3b, eff stack is too short

reggy SB isn't wide here vs our reshove stack, its 3rd vs 2nd with shorter stacks around

preflop: fold with your reads that reggy SB doesn't steal much

flop: as played, flat I guess, but I would never find myself in this spot, I don't like bluff raising, we must fold vs 3b shove

turn: as played, ok I guess

river: as played, odds call, but I don't like it

shove preflop seem fine, flat seem reasonable. Player dependent.

I would flat flop, i don't see much reason to raise it.
After that nothing else what can do.

I agree with other posters. I think the biggest mistake is the flop raise. Normally you are pretty much exactly getting called by better and folding out worse (notwithstanding the hand results this particular time).

Blind on blind I think we need to shove pre flop here.

If we flat the flop are you calling again if he bombs the turn?

What cards are we calling the turn with?

if SB shoves pre its a fold, ICM tax is huge in this spot because of shorter stacks

so unless we have reads/stats that SB r/f wide, i'm not 3b shoving, im folding

Overall my gameplay script with this hand look like this:

Preflop
If
A[player is more passive and we believe he will not 2-3 barrel postflop often]
Action >> flat or 3bet allin depends steal %
B[player is more aggressive with high potential to go for 2-3 barrels postflop]
Action >> 3bet allin only, too low postflop playability

Flop [only if preflop A]
If
[A1][flop come wet and we miss it]
action >> fold
[A2][we flop a high, 1 pair hand on dry type board]
action >> depends, mostly calling 1 bet with think in mind that this player have low potential to 2nd barrel.
[A3][we flop 2pair+]
action >> not relevant/depends

Turn after action [A2] on 269 rainbow or similar board with A6o hand:

Player type [A] have low potential to use right spots to double barrel and we are folding 6 to any reasonable sizing on any overcard over 6 except if it improve us.
By teory player on sb would exploit us very massively if he is capable double barrel enoght it but we not expect that based on our preflop line.
Basically i am assuming 2.50$ players will not double barrel enoght and give up too often after 1 cbet especially on dry boards, if we suspect specific player don't do it >> we 3bet allin preflop.
