NL10 SH Speed A8 BTN vs SB TP

I dont like your size pre looks fishy to me,on turn you dont have set but trips and shove is you play there vs a shortstacker fish.

I would check back the flop to start with. There is very little value in betting, I think betting is +EV but by checking you allow him to bluff his 0% equity hands on the turn so it's more +EV. Most bad regs just auto fire turn when you check this board, so you get at least one street of value. Agressive fish will just pot/pot all their air, so just let them hang themselves.

If he is a reg:

By betting flop, you leave yourself in a weird guessing spot on the turn and you make him fold all his air on the flop. He probably doesn't call any worse hands if you bet again. So I'm checking and bluff catching any river except for spades unless he makes it really small.

If he is a fish:

bet/bet/check-call or check call down. Are the best lines on this board. You'll often see 1 spade hands call twice then bluff river, or by checking they just fire three times with air.

with 15bb effective after the minraise on the turn, I would just get it in here because you're going to be facing an all-in on the river by villain anyways.

Also, if we are behind, we are still live.

I would play like you bur go all in turn
