This is a discussion on AA vs river overbet within the online poker forums, in the Tournament Poker section; I should have just made it pot size bet on turn. But what you are doing on river? As played are you calling that or
without reading on vilain it's a bit hard to say... looks like it happened deep in the tourney.. he probably had a good read on you and knew you weren't playing the flush.. so he had position and he did..??
I would have tried a bet pot size post-flop (and maybe overbet +1BB).. trying to protect from flush draws and make fold week pairs and stop right there..
I find that flop crazy for aces.. straight draw, flush draw.. then a deadly turn.. then, if it wasn't enough: rivver killer opening to a full house.. however your opponent called a 4x raise preflop so... he probably have something strong like an over pair also..QQ, KK.. pocket 7 is also a possibility.. limit 88.. 56, nahh... 2 diamonds.. KQ-KJ? can be at this point in the tournament, but you don't usually flat call with these two..
This is a very tough spot. The straight got there, paired board got there, flush got there. Yes you are holding the A of diamonds for blocking nut flush but when he over shoves the pot on the river you can only put him on two things, made flush or straight bluff. The paired board doesn't scare me at the end, cause it was runner runner. If he flopped a set, I would see him bet a lot more. In this case, I think a fold is the best move
I feel like you can eliminate a lot of overpairs and big aces here because he limped on the button and called your raise. Maybe trapping with AA-QQ, but I can't see a hand like 10s limping here. You having the A of diamonds blocks a lot of Ax flushes. I also can't really see him having any 8x here besides 87. So basically he either has a boat, or a super spazzy bluff in my opinion. Once in a while he'll have suited broadway in diamonds...but it's a bit weird to overbet jam with that hand, better chance to get a call for 20 or 25 BB. I think this is an easy fold. 44, 33, 77, 87 all make so much sense to limp/call on the button.
Without having any specific details on villain's tendencies I would fold here. AA probably not good here with flush, straight and possible trips. The BTN limped so could have anything. Sucks to fold AA but sometimes just necessary.
For me interesting is the moment after the flop when you see 743
You bet and get a call 6.5BB.
At this point you may decide if he is bluffing or not.
If you decide he is not bluffing , you should fold.
If it is a bluff, then also the river bet is a bluff and there is no reason to fold out.
I would probably not bet immediately after the flop trying to 'hide' AA.
Ill tell you why this is the easiest fold of your life and you should never allow yourself to be in this position in the first place. Only the real rookies make this mistake and I see evryone do it so everyone must be a rookie... BECAUSE WE ALL KNOW YOU FOLD AA PREFLOP!
