What is the correct play here?
I feel that any cbet will commit me to the pot, so is all-in an option? check/fold is not an option, right?

Hero should have shoved PF.

cbet looks more normal than an all in therefore less likely to get called

how much would I cbet here?
half pot is almost half of my remaining chips, so less than that?

I'm leaning towards this too.

perhaps.... hero has 17BBs, and it's hard to commit 400 OOP.
I might just check here. as played c/f the flop.
