I do want to play it. The only time I would consider not playing it is if my equity is larger if I fold it.
Let's do the equity calculation and see where we land, and make some numbers up.
3 people are all-in before the action gets to me, and they all have me covered. This is important, because it means that no matter who wins the hand (other than me) I'll end up on the bubble, as I'm the short stack. Let's say that my stack is 10k, and it's the WSOP main event. If I win, I figure to go up to 40k stack, and if I lose, I'm gone. Let's furthermore say that I'm 50% to win (someone can check with PokerStove how likely I am to win against some decent range of hands these opponents might have)
The prize pool of the main event is roughly that of the buy-ins, right? So that makes it very easy to calculate:
Presuming that I'm as good as the rest of the players here, or rather on average as good as them, my equity will be whatever my chipstack is. Or conversely:
If I fold, I have an equity of $10,000.
If I call, I will have an equity of $40,000 half the time, and $0 half the time.
Clearly, calling gives me an average equity of $20,000 and is the preferable option.
I think I did this right. Let me know if I screwed up somewhere.
