On the flop, I'm not sure what the best line is.

If we shove, we can potentially get a better hand to fold: against such a loose player it's never a guarantee, but if we can get them to fold any pair 44-JJ and any A/K-high hand that doesn't have a draw on this board, we deny a lot of equity and get to draw heads-up against SB.

And if we shove and get called, I believe we only need about 25% scoop equity to be GII good. If CO is only calling a range of (Q, KK+, dd) and depending on a reasonable guess for what SB might go all-in with preflop, we have at least 27% equity in theory, from what I'm seeing in PPT.

However, we could also check/fold or check/call.

Check/folding has its merits, though we're liable to be folding a TON of equity.

And there's a specific reason I may want to check/call this flop: CO, while not especially bluffy according to my read, had made a $250 river shove on (I may be slightly misremembering; it's hard for me to look up this hand being an Ignition/DriveHUD user) a 23463 no-flush board with T864 (and no missed flush draw; it wasn't really a reasonable bluff... they got looked up by a "gutsy" 57 to lose the $650 pot I mentioned). If we shove, we could get something like (A!Q!TT+!dd) to fold (and that's good re: getting heads-up), but if we check we could get something like that to shove as a significant underdog to us heads-up in the side pot. (Wishful as that may sound, don't forget that CO is pretty maniacal, so who knows the limits of their spew range.)

So yeah: I'd love to hear how folks think through preflop and flop. As I mentioned, the preflop situation is one I keep finding myself in (especially with 1-2 maniacs at the table), and I'm not sure if I'm playing it right. I've included a bunch of my thoughts on both streets... hopefully folks find this big PLO50 hand interesting.
