Otf after everbody called i thought im done with the hand.Was sure somebody has a set.
But now there is the interesting river.

Fold pre. As played it’s closer to a fold than a raise but call should be fine.

Fold pre.

Ap i sigh call

Call. Weird line from Villain. Doesn't make too much sense for hands that beat Qx.

Fold pf. As played, call the river getting over 4:1. Expect to be beat a better FH frequently.

Interesting that 3 of 4 replies so far suggest fold pre here even though the question is about the river play. Isn't it good to mix in some calls here as long as you're able to fold post flop? I realize it's the first hand and we have no reads but is calling really a leak here?

As for the river play I agree with ATC, just call. No hand that you can beat will call your raise, and the hands that do beat you can 3 bet, don't see any value in a raise.

Calling in these exact positions vs this raise size is a huge leak and is bleeding money

Yes it's a leak. Play very tight in EP vs a raise from unknown. There's no reason to use a mixed strategy of sometimes folding and sometimes calling.

If I'm Hero I just flat call OTR. If villain has 8x Qx PPs and bluffs what calls a raise? Just the 8x and Qx probably (maybe larger PP like JJ) and we chop Qx.

You guys are so far over the top, calling KQs here is not a "huge leak", it's fine at standard LLSNL tables. The critical question is how often it gets threebet behind us, if the answer is "lol threebets they're those things you do with AA and KK right?" like it normally is, then calling is perfectly fine. You just have to be careful postflop, like if villain led 3/4 pot into the crowd here, then I'd just muck. If your fear is simply getting threebet, then do you also open fold KQs UTG? Are you under the impression that the difference is stealing the blinds? From UTG on a LLSNL table?

Weird sequence of events here. I can't say I'm in love with my hand but it's worth a call. Raising is out of the question.

KQs is fine as an open UTG+1 but not as a call IMO. Yeah you steal the blinds sometimes and that shouldn't be dismissed outright but mostly calling is bad because unless UTG is a LAG we aren't doing well against his opening range (ldo), and we don't have the initiative post flop making barreling tougher. In addition our range is capped, which anyone paying attention can see.

And if we suppose we get squeezed with TT+ AK with 7 players left to act there's about 2.7% chance per player or 1 - .973^7 = 17.4% chance we get squeezed and have to fold. That's not insignificant, and we should note it's more tempting for a player to 3-bet when there are overcallers so it's not directly comparable to the risk of being 3-bet opening UTG.

Certainly if I see an open and a bunch of folds vs an open and a bunch of calls I'm going to want to 3-bet more often in the second scenario since the overcallers usually fold, adding a lot of dead money to the pot.

I don't know if it's a "huge" leak to call particularly as KQs (but not KQo) does okay multiway, but certainly I think most people cold call way too many hands vs. a raise.

And I'm certain opening KQs UTG is more profitable than cold calling KQs UTG+1 despite your dismissal of the differences between these scenarios.

I called pre because i can easily fold postflop when i think im behind and i think i have an edge over most 1/2 players where i play. And from my experience people at 1/2 have almost the same opening range from every position. So if a guy raises from ep it doesnt necessarily mean that he is raising tighter from this position than he is from HJ or CO. I see all the time people raising like KJo in ep or J7o because it is their favorite/lucky hand lol.
And if someone behind squeezes its an easy fold because most people at 1/2 dont do that as a bluff. If they do it they usually have it.

I called otr, everybody else folded and villain mucked. He said he had JT
