PLO 100 weak aces

I don't understand why you bet this flop. It's pretty much one of the worst flops for your hand and one of your 2 opponents is likely going to be favourite over you here.

I would check behind and pray that the board pairs on the turn (or obviously you hit your miracle non flushing ace).

I think this is quite a trivially easy check behind on the flop and see what happens on the turn.

Because I thought I was a favourite over BB's 85% range , that is commited to pot here (he only has 21 left), and I was expecting UTG to play quite straightforward.

I didn't want the turn to be like a J, BB would shove, UTG fold and I wouldn't know what to do.

This is why you check. If you think BB is shoving any 4, then let him do that on the turn and UTG will be forced to make his decision before you, which is good.

The problem for you is that UTG knows what you have (he puts you on 2 aces) so when you actually have 2 aces with no redraws whatsoever you can never bet as you have to fold to a checkraise and he is going to play back at you with any piece of the flop.

You're an underdog against any 4 random cards. Do not bet this flop, it is a bad flop for you.

there is basically no flop that u like except if u flop an ace...maybe the nut flush draw...so why even 3bet pre? just call and check fold flop imo
