I played in a $33 mtt with AllinBigUnit4. It was a early on in the day, so I was pretty sure he wouldn't be multi-tabling too much. I opened Ad4d spades in early position with over 75bb's. and he flatted in the sb. I decided he could have a wide range of hands considering he probably was cognoscente of the fact that I wasn't a winning player. I also realized he could have a very good hand as well. The flop was 3-q-7 rainbow.... 1 spade. I cbet and he flatted. I figured that he was a good enough player to float me with hands that may or may not beat me.... and he might turn them into bluffs depending on impending action. So I decide to shut it down OTT unless I turn some more equity. I peeled an off-suit J and decided that it seemed like a good card to fire one more bullet @ about 1/3 psb. He woke up and check/raised me and I decided to call with the intention of perhaps making a play Ip. The pot was approximately 40bb's and we both had over 50bb's left behind. I figured even if he did fire the river I could make a river 3bet jam and look incredibly strong. I know his c/raise on the turn was pretty polarized, but I was IP. Also he is a very competent player IMO, and I figured he could lay down a very big hand if he bet a polarized range on the river and I shoved giving him a great price to make the call. I mean if he makes a 20bb river bet into a 40bbpot and I ship 55bb's it looks like a line that could never be a bluff coming from me. I mean he gets 3.5: 1 on a call. I actually caught a perfect river card to bluff. The river was a 10. I figured that thi was the gin river card. I know that sometimes he c/raises the turn with AK, but it seems like an obligatory spot to represent if he bets. He id bet about 40% of the pot..... about 16bb's into 40. I kinda knew he had a 2pair+ hand at that point. I decided to stick with the plan and shove. He tank folded after about 30 seconds of time banking it. Immediately afterword he stated that was a both a sweet river 4 me; but also a pretty slick river fold by him. He claimed to have folded a flopped set of Q's. I want your take on this hand. Vs a random player given the action, do you think folding trip Q's on the river is a credible lay-down? I honestly think any 2pair+ hand that isn't Ak for the rivered straight is almost the same hand. I can credibly see QQ being a call only in the sense that a random villain could shove a turned set of Jacks on the river for value. I honestly thought he would fold qj and a flopped set of 3's or 7's...... plus obviously all his air. Do you think given the action, that I am being over optimistic that a very solid reg would fold a flopped set of 3's or 7's? Do you think it's credible he had a set of Q's? Given the dynamics and the way the hand played out I think it isn't, but I would like your opinion. Give me some feedback about the posted hand though. I think a reg could call QQQ and JJJ but laydown QJ and 333 or 777. How would you play the river vs someone like me there? I suppose you check and begrudgingly call? If you do bet for value and get jammed on in a spot where you are getting 3.5:1...... what hands do you find a fold with? Do you fold 333 and 777 but call QQQ and JJJ? Let me know man. I think it is a very interesting hand.
