If I understand this right, you're saying I should play 66 with everyone in the pot, costing me 50bb's, a chance to win a total of maybe 56-62bb's? 66 does not play well vs. multiple opponents...neither does AA, for that matter.
I'd probably fold here, unless I had a very, very strong feeling that everyone at the table was playing trash.
Love the discussion!
my apologies, i edited that part out because i didn't think it was necessary to include in the point i was trying to make. i'll add it in for others that are reading this.
it's the final table.
bb: 50 bbs (you)
utg: 100 bbs
all other players have 2 bbs.
utg shoves for 100 bbs, everyone before you calls, and you have 66.
in this scenario, this is a clear fold. why? because 66 is going to be a close
equity spot preflop against utg's range. you're not concerned about the other 7 players with 2 bbs as they can't bust you from the game, only utg can. you also have 2nd placed locked up. you don't want to risk busting out of a spot that you're virtually guaranteed to finish in in a close equity spot. even if villain has 78o and you have a slight equity edge preflop, you still lose ~50% of the time and risking the chance you getting knocked before 2nd place, when you have it locked is devastating to your roi%.
do you need to know utg's shove range to make make this fold? do you need to know if utg is going to jamming 10% range or 100% range here? do you need to know if utg has made plays like this before? what
hands they went to showdown with? no. that information is irrelevant. you should never be calling here in a marginal equity spot that's going to potentially risk you busting out of a seat you have locked down.
what about aces? well, you mentioned that they don't play well against multiple opponents, but are you really concerned about aces's preflop equity going down against 7 players with 2 bbs? of course not. your only concern is how does aces play against utg's range? and it's a lot better. now you have a huge equity advantage over utg's jamming range, making this an easy and clear 100% call. again, you don't need 100% information to call here.
the point i'm trying to make is that, yes, information is important sometimes. there is no denying that. if you're at the river with the 2nd nuts facing a huge overbet and you're trying to figure out if villain is overbetting with the nuts or making a play with worse, yeah, dig into that information bank of yours. but there are times where you don't need all information to make a clear decisions.
going back to the original post, op didn't give enough information and i made a sarcastic comment about this spot being a 100% call or 100% fold or it depends because, no matter what op says, it's going to fall in one of these answers.
