am i allowed to post multiple hands at a time?

no reads, default assumption is all "unknowns" as this is my 4th or 5th session at 8/16

1) KK in sb, all unknowns except CO (i dont know what i know about him/her, its just written like this in my phone)
MP open limp, CO and button over limp, hero raise, BB call, all limpers call

Flop AKx rainbow hero checks, mp bet, co and button call, hero call, bb call
Turn x hero check, bb bet, mp and co call, button fold, hero raise. bb, mp, and co call
River Q hero bet? bb fold mp raise co fold hero call? or is this easy b/f?

2) 55 in bb, 4 limpers pf hero check
Flop A44 1 heart: hero check, utg1 bet, mp calls, hero raise both call
Turn 2h: hero check utg1 bet mp call hero call
River: 3h checks around.

^ did I miss a river bet here? i was thinking a check/raise possible

3) QQ in button
HJ open raise, CO call, hero 3!, SB calls, HJ cap, call call
Flop 972ccx hj bet co call, i feel i should raise here but i call, sb calls
turn 3x checks to me, hero bet, CO call
river 5x CO bet, hero call?

4) 99 in mp; utg1 is unknown but i deem a reg because runners/dealers saying hi to him
utg1 open raise, hero 3!, SB BB and UTG1 call
Flop 62J rainbow, sb bet all in for 3 chips, utg1 call hero raise for side pot utg1 calls
Turn K: check check
river 2 utg1 bet, hero call?

I think you should break these up into 4 different posts.

I'll chime in hand 1 for now. I would bet the flop....As played I would CR the flop....As played the Turn CR is good...I would call the river given the size of the pot and the strength of your hand. It's not looking good but maybe MP is overplaying a hand you beat.

Why did you play the flop the way you did?

Hand 2) What is your reasoning for raising the flop? I'd probably bet and as played just check/call....As played the turn check/call is good. You should donk the river when the 4 straight comes out. 8/16 players are notoriously passive especially on perceptually scary rivers.

in retrospect, I actually have no clue. I'm pretty sure at the time I was thinking: let late Aces fatten the pot and hide strength, let them improve to 2pair and trap on turn

I am almost positive I went for the free card here.

I definitely shouldve donked river, I figured I had best hand but was going for maximum extraction (fancy play syndrome?) with 2 left to act, and me showing weakness. i thought someone would bluff this street

what if river here was a non heart 3?

You make it sound easy. The odds are they will not improve to two pair on the turn. Also, this is a board where players may sense weakness and stab on the flop but shutdown on the turn once there are calls. You got lucky this time to get some action on the turn. You're basically announcing you have a monster as played. With a hand this strong you should just bet the flop and hope to get raised by an Ace. You don't want to give a free look to someone holding a gutshot. Maybe you get a chance to b/3b the turn by leading out.

It's tough to get a free card when you are OOP.

I would donk any 3 river. Notice by checking you made zero bets. If you did get in the CR and were 3 bet your probably losing 3 bets. Getting in one bet on this river is plenty. Also there will be times you check and it gets bet and they just fold to your raise. I do think this is FPS because what you are trying to accomplish is rarely gonna happen. It's just not gonna go bet bet bet CR call call call. This assumes you are playing with semi rational players.

Hand 3) I would raise the flop especially MW for value and protection. I would consider raising the river but absent reads I'd just call.

Hand 4) I like the flop raise. I would bet the turn and check the river. Your still ahead of QT, AT, AQ smaller pairs. Checking the turn and calling the river is gross especially in a side pot. I wouldn't be overly concerned he is slowplaying a monster since he didn't cap pre.

Hand 1 I don't like the slowplay. I don't mind check/raising the flop, but I'd rather b/3b if possible. I've mixed in both strategies so either way works fine.

Seems like you have some FPS? I don't mind mixing up your lines some of the time but would rather not do it in the type of loose passive game that you seem to be playing in. Sounds like a good game btw, good luck.

Posting one hand per thread gives you better responses.

Hand 1:

Preflop is fine. Bet the flop and 3b if raised. You've flopped a set of Kings ffs, play it like a monkey.

Bet the turn, but fine as played.

River: Bet out and call a raise, if a gutter got there, so be it. *Never* is a bad word in poker, but I am never bet/folding getting about 18:1 on the call. Besides, the way you played the hand under-reps what you have big time.

Hint: if you're even considering bet/fold OTR in a limit game where the pot's not tiny - just x/c. Folding your set of Kings here is potentially an 18 big bet error.
