It wasn't the river that scared me – I was more thinking have we been firing into a set/2 pair on the other 2 streets as our range early in the tourney and UTG+1 looks super strong so I wouldnt expect to be getting called down by worse for 3 streets? is this a floor in my thinking?

Im with Benny on this one!

This is what I was thinking, am I ever getting called on the 3rd street with worse?

My range here should be polarised with AA/KK/AQ/QQ and so other than QQ we should expect villain to be check calling 2 pair/sets right?

In answer black he flipped over JJ so no hidden bad beat story here 🙂

Just wondering if I missed value here/whether he would even of called/if this is a small part of his check calling range and usually he is stronger?

I really dont understand the fear of 2 pair/sets OP, maybe Im not giving him enough credit but his preflop action is indicative of mid strength pocket pairs/suited broadways, so i dont see many sets in his range at all bar QQ which he probably leads the river.

Def bet for value on river

I'm surprised no-one has mentioned this yet, but I think that this decision needs to be made on the turn, not the river. 
You have AA in position on the turn in a headsup pot on a board showing  Q 7 25. Before you automatically bet here, you must decide if you are going to go for 3 streets of value or just 2. 
Whether you can get 3 streets of value or not will obviously depend on several factors; image, opponents tendancies, if your opponent is tilting or not, what level they are thinking on, etc.
If you come to the conclusion that the situation warrents only going for 2 streets of value, then I would recommend as a default line vs most players to check behind on the turn with the intention of either calling a river bet, or betting for value on the river when checked to. You stil get the same amount of value  from Qx, JJ type hands as you would have if you had bet the turn, except now you save money when you're beat, or if they improve on the river. You even still get the same value from flush draws vs alot of players, as they will often bluff the river if you check back the turn. You may even get looked up by a floating A-high, or a weak 1-pair hand this way that would have just folded if you had bet the turn.

Now obviously this line has it's flaws as well, you miss out on value from flush draws vs players that won't bluff when they miss, and you become predictable if you allways use this line, so it's good to mix it up. I would much rather just fire the turn again vs passive calling stations for example,  but then I would probably be going for three streets vs them anyway. And sometimes your opponent will catch a miracle river with their gutshot that they would've folded if you had bet the turn again. But these suckouts don't happen very often, and the many times that they bluff the river with their missed gutshot will more than make up for it. 

So in general I think if you're only going to go for 2 streets, checking back the turn is the superior play, but whatever your plan is, make it on the turn. Or better yet, the flop.

Surprised there's not more talk about villain's range for 3betting and flatting a 4bet OOP 250bb deep pre-ante. Assuming villain is vaguely competent, our line of opening UTG+1 and 4betting him when he 3bets OOP is just gonna look ridic strong, so when he flats OOP I doubt he's doing it lighter than TT-QQ, probably not with AK because it plays so badly OOP, and probably not with AQ because it's such a thin 3bet pre. We also have blockers to AK/AQ, which means it's overwhelmingly likely he has TT-QQ, maybe 99 or 88 if he's loose.

When the board runs out the way it does, there's almost no way he has any 2pair combo and the only set he can really have is QQ, which he almost always raises on flop or turn anyway. This leaves us with JJ/TT/99, where he's in a tough spot on the turn but is gonna very often convince himself to call turn and river because lol we must have AK. There's very little reason for us to fear anything on this board unless there are specific dynamics at play, which there aren't gonna be this early in the tournament. If villain keeps checking, we keep betting.

easy river bet. agree with theginger45. and i prob dont shove river since its for his tourney life in the warm up but since he is so retarded in calling your 4bet pre and then c/c down he might just call it off anyway since you obv must have AK. really close between betting like 3456 or shoving.
