First hand against unknown villain. I got myself in a lot of trouble very quickly this time . Is my line OK?

Check/jam flop.

I don't mind your flop raise and turn barrel but fold to his raise

flop raise is way too big...just shove if you wanna c/r 3x

Sizings are terrible. You committed 440 out of 500 chips and then folded. Ouch. Be more aware of the pot commitment line and when you cross it, do it by jamming to maximize your fold equity. At 25BB you don't have enough room for this line.

+1

do it 100 on flop and shove the turn...

Ouch indeed. These are the kind of hands when villain does fold on flop or turn i wouldn't bother too much about it, but when he doesn't, it shows that this line is not optimal at all.

I guess here, either check/jam, or check/raise smaller (call a 3bet jam from his side??), and if he flats my check/raise on flop either give up on turn or jam turn. So many options, i wouldn't know what is the best line here .

I did call turn because with his raising size i had to put 140 to win a pot of 740. I did not expect ANY fold equity at all from that point on, so this is how i played it on turn and river, finally hoped to win the match with my last 60 chips

Your c/raise size on the flop is fine if you intend to shove almost all turn cards. On this flop, I would rather c/shove though. C/raising to 120 is probably best on low cards board when a lot of scare cards can come on the turn.

So yea, shove turn if you go with this line next time. I don't expect that many 4x in his range after the big check/raise on this flop. If it was a J or A turn, I would check/evaluate.

what is the obvious advantage of jamming turn instead of betting t140? you guys mention fold equity, you believe villain will fold Jx to a jam but call t140? or KQ,KT,QT?

yup, this is why i betted t140, because i didn't think a larger betsize would change the FE, maybe even on the contrary, because with a non all-in bet i could still represent TP, or any hand that wants to extract value. When I look back I prefer the idea of just giving up on turn, also seen that turn pairs the board.

Yeah I don't like a flop jam in general at lower stakes as I don't think you have as much FE. Got to jam turn though, or fold to that raise I think as played

c/155 OTF shove turn. hate a c/shove on flop

Why cr instead of CC?
