Weird preflop spot, $1/1

[wazz]

I'd say that my best street in PLO is preflop these days, but it used to be the turn.

I'm like 95% that CO has aces, but he will occasionally make this play with kings given he's seen I'm willing to jack it in preflop with not very much. The rest of the preflop callers are awful and will gambool with crap.

Seems like a no-brainer to me after all of those donks flat call the $18, you're calling whatever reraise / etc. Is there any specific commentary you're looking for here? Looks fine to me -- I mean, if it had been all folds to the CO who repots it again, then you don't love having a pair in your hand against what appears to be AA, and he's got less than a full stack to go after.
