9 handed game. Big fun player who is known to pot and repot blind straddles to $20 on the button. I have ~$900 in the sb and am covered by everyone. Good reg to my immediate left but everyone else tends to be loose and pretty passive except for two guys who are overly tight and decently aggressive.

I have KK93
Is this a fold, call, or pot?

I opt to call and we go 7 ways to the flop: KJT
Check or lead out?
I opt to check and tight player bets 1/2 pot, folds to me, pretty sure this is a standard call.

Heads up to the turn: 8
I check and opponent bets 1/2 pot again. I have a gut shot that probably isn't good and while this opponent may bet flop with a worse set on the flop, I don't think he continues turn. Best case he has a club draw somehow or stone bluff? So should I fold top set here?

I end up calling and the poker gods reward me with K on the river (daily quads). I'm confident my opponent will check back a straight on the river so I lead 2/3rds pot and opponent snap mucks Ahi straight face up. What would be a better river sizing?

bet $50

call turn and pot any paired board/club river. flop ich check/call depending on size, not leading into 7 players ever

Thanks for the replies. Any comments on preflop?

i would fold utg, but given youre in the sb an there has been some limping going on allready youre fine to set mine so call seems fine, never bombing it..

You played the hand fine, as long as you're leading this river with some bluffs w/ relevant blockers like QJTx for example you can lead this river with your boats/ quads. Sizing isn't too important, villain seems like he's probably folding to any reasonable bet if he's playing pretty snug and doesn't think you get too far out of line.

Fold pre imo.

You are never getting a,single dime from villain on the river so question is completely irrelevant.

Pre is interesting tho. You can actually fold without looking at your cards since there is no profitable hand from SB to a BTN straddle. I would call with a 4 card ds rundown and thats about it. Maaaybe limp AAxxds
