1-2 NL Holdem at my least favorite poker place, charges 10% rake up to $10.

Villain 1, mid position, middle aged heavy man, has about $50 in chips.
Villain 2, young kid, Hijack, just sat down. No info on him. $200 in chips
Villain 3, younger kid, just took an absolutely horrendous bad beat. Had pocket aces, goes all in and gets beat by a set on the river. Now totally on tilt. He has already swore at me once. he's totally red and on the verge of tears. Re-bought for $150 he's UTG

Villain 3 raises to $12.
Hero, sitting to his left, calls with 6c 7c

Table is fairly tight, (the guy with pocket 7's left and he was the only loose player) I expect I am heads up against him.

Villain 1 goes all in.
Villain 2 thinks for 2 minutes and then calls.
Villain 3 then goes all in

Would it be crazy here to call?

Yes it would be crazy.

Yes, it would be terrible

my god, fold the first time around and, of course, the second time around.

Just what hands do you think you have enough equity against?

Villain 1 had A-Qo
Villain 2 had K-J suited (d)
Villain 3 had A-Qo

If I called I would have won. Flop came out 5-8-9 but that's poker.

You only have any kind of decent equity in this hand because Vs 1 and 3 block each other's outs. The chances of that are slim.

Even being extremely results oriented, you would have 32.874% equity in the main pot, 32.545% in the first side, and 41.174% in the second side. You'd be paying 19% of the main (because you already paid $12), 33.33% of the 1st side, and 50% of the second.

So even against these exact hands you're only getting the right price in the main. Your EV would be +27.75 in the main, -2.37 in side #1, and -8.83 in side #2. Even in this perfect storm your EV is only $16.55.

Now let's figure it with ranges. You're paying the same amounts, and we assume that these hands are near the center of their ranges. You now have 21.81% equity in the main, 25.316% in side #1, and 34.94% in side #2. Your EV is +5.62 in the main, -24.05 in side #1, and -15.06 in side #2, for an overall EV of -$33.49.

So even with a hand that is very unlikely to be dominated by their ranges, this is a clear and obvious fold. Frankly, it does far worse the wider their ranges are here.

More rake is better. Find a different game

Oh, yeah. I forgot to figure in the silly rake. With $10 coming out of the main, your EV there goes down by about $3 in each of my EV calcs above, all out of the main.
