What could I do better ?

Open 3bb, c-bet flop is fine, bet turn is ok, check/fold river

Only thing I would change is the river. Okay yea you could raise 3bb pre too.

OTR you have less than a pot size bet effectively left. If you are confident you are ahead most of the time and villain calls you with enough weak hands, then just ship it. Otherwise I would check behind. I wouldn't go for thin value when in position. The scary card combined with your small bet could induce some players, especially recreational ones, to bluff you. You don't want to get raised now.

Agree with la55i, just check back if you are not going to call his check raise. You are blocking nut flush, however the board is very connected to the flatting ranges I believe, so only vs calling station I would go for value here.

Same here agree with la55i but i would like to see the stats of BB to have my own opinion , just out of intellectual curiosity.
Also i think on that table i would be more encline to make bigger PF bets even if it gets out of norms or obvious for observant opponents. Also if BU like to Iso Raise or just Raise very often i would maybe try a Limp expecting a raise.
Especially if BB stats are close to BU stats. But well i'm not a CG player and as we say in France those who give advices are not those who pay the broken glass.
Did you remove BB stats on purpose ?

Best of Skills & Luck @ Tables,

Well if you don't like multiway pots you could begin with opening bigger at micros indeed.
I also think the river is either a bet/call or a check back, especially with the ace of diamond.

I'm french and I've never heard it ♦

That is the worst thing you can do with AA preflop, does not matter what your oponent is. Any good reg would mark you as a fish after that play if you go to showdown

I don't mind what a reg or a good reg might or might not think about me if he tags me as fish it's even better in my opinion.
Don't really want a reg to tag me as a reg.

@MyFloXyBabY En Français on dit "Les conseilleurs ne sont pas les payeurs" , la version anglaise était pour simplifier la compréhension

Well I don't mind being tagued fish either but I'm not so sure about limp/reraising anyway. It's a play that polarize much more our range so in a way we're showing more strenght and if nobody raises preflop it's of course catastrophic.

@OldSchoolPapa même comme ça je l'avais jamais entendu tiens c'est marrant

I dislike limping here. I think it is a valid option only on SB.

The problem is that we could invite many players to the pot. MW our equity decreases. Also if no one iso-raises it is difficult to build the pot postflop without big overbets.
If someone does iso-raise and we 3bet him, then our cards are quite face up. I think people know limp 3bet means KK+ or if they don't know that they probably still narrow your range to the strong end.

Agree with @MyFloXyBaby.
If you dont mind being a fish in somebody's eyes, dont you also mind losing value and not getting paid vs most of the NL10 and above regs and better regs in NL5. You might be still alright with all NL2 pool cause they dont think that much anyway.
