Villain: 46/15, 3bet: 1.5, hands: 41

Call or not call the river? Or.... should I shove ?

Also is my flop 1/3 bet ok or should I go bigger or check?

SB: $12.87 (128.7 bb)

Preflop: Hero is UTG+2 with 9 8
Hero raises to $0.25, MP1 folds, MP2 calls $0.25, MP3 folds, CO calls $0.25, 2 folds, BB calls $0.15

Flop: ($1.05) 3 5 2 (4 players)

So fish, X/R you when you cb in 4 way pot, bets turn and then pot bets river...
Im snap folding.
Also his turn small sizing can still be strong and I have notice some fish being afraid to build pot with sets/2pairs when there are many draws, once draws brick they feel confident in his hand again.

About cb, I would not cb this multiway, imo you need to be more selective (higher EQ bluffs) I would bet Q-high/K-high fd

I would just fold preflop, on a 8-player microstakes table you are pretty much guaranteed to get one or many calls and forced to play out of position.

Wasnt a c/r but a reraise instead but doesnt matter which one it is I guess because it still represents strenght. And yeah I dont usually Cbet multiway flops. I guess now I saw that I have also some backdoor straights (6 or 7) which can give me more outs so I thought that I will stab with overcards + FD.

But I like that higher EQ thing when bluffing or semibluffing you mentioned! Good stuff!

Sounds reasonable. Hard hand to play OOP.

I checked my database of 160k hands and checked all the 98s I have opened from early and middle positions:

199 hands and -160bb/100 hands, EV -125bb/100

so yeah, I am not playing them profitably from early positions

From all positions I am +57bb/100 winner with that hand, EV +78bb/100

Im glad you brought this up, thank you! Im learning

I believe learning preflop charts and rarely deviating from them is the most important aspect of the game for us microstakes players. And I would almost never deviate in the first place when it comes to open. If you watch mid/high stakes crushers videos you'll see them saying things like "with the fish in the blinds I feel I can open 74s from BTN", ok but they are crushers and we are not.
Where we can start deviating I believe is with 3bets ("no, I won't 3bet A5o vs BTN because they're just a big nit") or 4bet bluffs ("no I won't 4bet KJs vs in position 3bet because this player is crazy and doesn't have a fold button")

GTOwizard has tons of free preflop charts for all sort of stakes and stack depth. At least I know by heart the open & 3bet chart for the stakes I play / 100bb deep / 2.5x open (this is the open size I use) and I have a good idea of the 100bb deep / 3x open one, because a lot of recs use the 3x open and what we call or 3bet is actually much tighter vs this larger open size.

Not saying it will bring you to 100NL by itself (proof: I still play 10NL) but will strengthen your game a lot still

I think you underestimate the skill diffrence between you and fish, when you are F.E. 5bb/100h winner while paying 15bb/100h in rake at the same time fish is losing -50bb/100h.... In other words the skill diffrence is so big that you are crusher in BTN when SB or BB is fish

Wise words! Most of the time I start the session in a mindset that "today I will play ABC poker" and then I end up in hands like these lol I guess it is a learning process.

Oh villain had A4o. Flopped nuts. That small turn bet really confused me to believe he had a busted draw. So yeah I called the river

Have you tried opening them and reviewed your results?

Just for reference, if a hand in 6max UTG is a 0EV fold or a mix, then it will generally just be a pure fold in an earlier position in a FR game. 98 also has a lot of reverse implied situations when it makes a straight or even 2 pair. If you get a lot of action behind you should also tighten up your opens a bit, which would just make this a fold pre.

This is really good, and important that you check into your database numbers like this. It sounds like you're taking the correct approach. It's a process, and we're all still adding to our knowledge.
