Me? I'd fold anything axcept AA in a shot.
But a good player might not.
For me, it (playing in the WSOP) would be an experience to savour, & I genuinely believe I'd have a chance of cashing, though very little chance of winning. (Which is half my problem). And I don't wanna gamble in a 3 way pot at this stage for all my chips, I'd rather "settle" & feel out the table, & try to play big pots on my terms, ideally one on one. The time to gamble is later, imo.
It is possible that I'd have a better chance by gambling, as opposed to trying to outplay folks. But if my - or your - even money shots hold up most of the time, as they do some nights, I can make the money, easy.
But as I'm unlikely ever to play the WSOP Biggie, it's all academic to me.
Anyway, I've retired from WSOP events - I wanna preserve my 100% WSOP cashes record!
"I don't wanna gamble in a 3 way pot at this stage for all my chips"
It's not gambling when you are a good favourite in the pot as otherwise you are saying you need to have the absolute nuts to put all your chips into the middle. With AA you have as good as it gets to the nuts pre flop against two opponents but not with KK or less.
Betting is the language of No Limit Poker and all in bets pre flop and all in calls basically shout AA KK or AK to you but when the blinds are small and stacks deep then they SCREAM AA and AA.
Hence everything other than AA ins eat 7 gets folded and the better players would see the bets in this way.
If by some remote chance neither of the first two had AA it's just too bad but a bare Ace against your KK still has a 30% chance of winning.
KK or worse is an EASY fold in seat 7.
However it is EXTREMELY LIKELY that you are an underdog and gambling if you call in this spot with anything less than Aces in seat 7 and no player of any note should even contemplatye calling with KK in seat 7 unless he had x-ray vision and could see his opponents cards.
This question demonstrates why position is so important. When you see this kind of action/betting before it is your turn to act you have no business being in the pot with anything less than Aces.
Had the betting been raise to 150 followed by reraise to 500 then its a whole new ball game but all in bets for 10k called by another player for 10k on the first hand is a totally unique and specific case that says AA is already out there.
This is the problem with hypothetcal non real scenarios and I repeat that in real life you wouldn't have a decision to make in seat 7. You simply call with AA and fold everything else.
