I'm dealt [2s][4c][5s] UTG and limp. Two folders then a muppet raises pot behind me and picks up 3 retarded callers. Muppet only has $13, retard 1, 2 and 3 have $55, $20 and $107 respectively. I have them all easily covered due to being such an awesome guy.

Back to me then and I decide to re-pot it to $27 which will put two retards all-in and make a serious dent in the stacks of the other two. However, I expect exactly zero people to actually fold here most of the time. I'm reasoning that my pot equity is huge and I shuld try to get as many chips in the middle while they're likely to call. Besides, even though they are retarded my post flop game is probably pretty bad too compared to a real PLO8 player.

Anyway, flop comes [Jh][8h] giving me bottom pair, backdoor 5-high flush draw and a backdoor straight draw (a.k.a a MONSTER) to go with my uncounterfeittable low draw. Retard #3, teh one with the big stack, checks to me. I smush.

Brilliant, genius, or just really good by me?

You're right that my EV preflop isn't huge. I ran the twodimes numbers against the 3 hands that went to showdown and it looked like this:

As Kd 6h 3h 45581 56684 317932 2376 42638 81713 783 0.190
Ac 5c Ah Qh 82845 107718 262383 6891 0 113196 11772 0.267
8c 7c 7d 5d 68262 135143 241213 636 0 119340 0 0.270

So I got a bit more than 27% equity hot-and-cold against those three. However, on the flop I push out another contender who has put in the full preflop raise. Since there are a few shorties involved too it is hard to figure out the actual expectation. On the flop against the hands that went to showdown, I'm looking even better:

cards scoop HIwin HIlos HItie LOwin LOlos LOtie EV
5s 2s 4c Ad 44 44 480 4 309 0 9 0.355
As Kd 6h 3h 52 97 431 0 0 252 0 0.141
Ac 5c Ah Qh 107 295 229 4 0 288 9 0.387
8c 7c 7d 5d 36 88 440 0 0 252 0 0.117

35.5% equity four ways is obviously quite nice.

All in all I find that these pots are one of my main money makers in this game, building a huge pot preflop with a A2wx hand, since people will often come along with naked A2's or even A3's. Here you have one guy with A36K stacking off and a low wrap in the mix. Of course there's also a double suited AA hand in there which was a bit of a surprise (since he just called/called/called).

Of course a lot depends on being able to backdoor a 5-high flush and hit the nut low for a mega scoop and busting 3 players, and not everyone has those mad skillz, but if you do, like me, I suggest getting it all in.
