So i was playing at a 10/25c 10 people ring game right..
1 guy limps in on early, some guy limps in middle position...
im dealt QQ on the button and i bump it up to 4x bb..
sb calls, bb calls, and so do the 2 limpers...

flop comes:

2 5 6 (2 and 6 are suited of spades)

everyone checks it to me.. i throw in a potsize bet (about $4.50)
the sb calls out of position..
everyone folds

at this point i put him on a set.... like pocket 55 or 66, or even KK AA, possibly JJ

Turn comes:

7 of spades
making the board 2 5 6 7.. (567 are suited of spades)

one of my queens is of spade, making me 4 to the flush
he checks.. i check..

River board is:

2 5 6 7 Q
i make my set..

he bets the size of the pot, and puts me all in.. at this point i figured that if he had flopped a set.. that i have him beat.. and since i bet the potsize on the flop, i didnt give him any potodds to call me down with the flush draw..
so i figure i have him beat here...

i call...

he flips over A K suited of spades... he made a flush on the turn!!!



should i have known? when should i have known? was my river call a bad play?

hard to get away from top set, though the flush had to be on your mind, even though he maybe shouldnt have been in on a flush draw according to strict pot odds. hard to shake someone who flops 4 to the nut flush with 2 overcards to the board though.

Have to agree, A couple of little things I may have done differently but ultimately would ahve ended the same way.

I would have raised more preflop maybe 4 x BB. But AK suited would have called I guessing. The second thing I would have done differently is that I would have probably gone all in on the Flop. No overcards, there is a straight possibilty but you have to dismiss this given the preflop call, the flush would have had a hard job calling the all in, you would have been favourite by a bit.

In short not much you can do here, whatever you did it would be hard for you to fold your set. Of course you could have been tight and folded the bet - but what if the guy had AA or KK v your set? I think you just have to accept that sometimes things like this will happen. It also largely depend son how well you know the other player and what he is likely to call with etc..

Other than possibly raising a bit more on the flop and then definitely betting the turn to see where I was at (would have saved you the river bet) there's nothin much more you could here, I guess the old "you were either way ahead or way behind" applies here...thats poker.

If this guy (SB) is anyway a good player, I am not thinking pocket AA, KK, QQ or JJ once he just calls the pf raise with 2 limpers still to act. He would have (should have) re-raised for value and to get heads up with just you. That he didn't re-raise the A-Ks gets my respect as I don't like giving up this kind of info from the blinds either. So I would put him on a small to mid pocket pair, overcards, or a connected flush draw.

The flop bet was good but at pot size, you only reduced the pot odds to 2:1 while with 9 outs for the flush and 2 draws, the draw odds were 1.9:1 so he was correct to call. You would have to bet $5.50 to get the pot odds below 1.9:1 and for the SB to make a mistake by calling - Sklanski's Theroy of Poker. If he just calls a pot size bet, I will eliminate the small to mid pocket pairs figuring these as too expensive to chase - unless he's a calling station or a fish, then you just don't know as they chase almost anything. He could have re-raised with a made set but may have decided to slowplay them so I cann't eliminate that possibility yet but un-suited overcards would have folded here, so I can eliminate them. I'm leaning toward the flush draw as the strongest possibility with an OESD as 2nd possibility and a set on slowplay as the 3rd.
The turn. If the SB was on a flush draw (or the set) and was check-raising me, a check-thru is usually the correct play ON THE RIVER. On the turn however, you are still trying to protect your top pair and not only is a made flush now possible but a str8 flush as well. I think a bet is needed here but rather than a full pot size bet, go with the same size bet as on the flop - this gives about 3:1 pot odds which is less than needed for a str8 or flush draw. If the SB raises, you have your're confirmation (you are now behind) and can fold. Of course he may just fold and you win it right there but if he just calls, it means he's still on the draw but highly unlikely for the flush. Slowplaying the made flush to the river is a fish strategy, a good player isn't going to give you a chance to outdraw him with a boat when he has the chance to put you all-in right then and there! Calling on a draw would also be a mistake odds-wise so according to Sklanski, you should be welcoming any calls on the draw to the str8 (and the slightly possible back-door flush).

The River - if the SB leads out as he did, just call it down. If he checks, I would think I was way ahead and bet out hoping for a call. If he re-raised, I would have to figure a trap was set and I stepped into it or this guy is one hell of a bluffer! But without the information that would have gained on the turn with a bet, it would be tough to figure out! Maybe I'm all-in too.

I agree with the above, but if he checks to me on the river, I check it down. The set is a medium strength hand at best here (with the possible flush and outside possibility of a straight). I know others disagree, but I try to never bet medium strength hands on the river. You'll usually only get a call when you're beat.

Honestly its not that bad of a play to call your bet on the flop...

He know you dont have a set right now, or you would have been a bit less agressive, so 95% of the time A and k are also good... gicing him 15 outs, and maybe already the best hand...

In fact I wold have raise that flop with AKs, but calling is not that bad of a play IMO.

KJ

Good point on the 15 outs - I should have included the 6 outs for Ace and King as overcards and not just the 9 for the flush draw or 8 for the OESD. Counting all the outs @ 15, the best way to cut the pot odds down on the flop would have been go all-in which would also remove implied odds. This being a 'take a small pot win vs a large pot loss' strategy.
But then again hind-sight is so easy isn't it? I don't see myself going all-in on the flop with just an overpair.

Easy for me to second gues!!

KJ

If he knows all the cards... isn't 15 outs twice a favorite there? Meaning that he should have called ANY bet, no?
