I actually prefer to x/r flop since this board is better for our range than his so there should be a lot of fold equity.

As played turn can't be too much of a mistake either.

Obviously against his actual hand we're not in fantastic shape, like 30-35ish%, but I think overall you're not making a huge mistake since I think there's some hands he might barrel here that we're either doing fine against or have some fold equity against.

would also c/r flop

surely x/r, everything has been said.

x/r the flop was my initial reaction (before reading the other comments), especially as flush draw is to the nuts and villain has a lot of hands that he'll c-bet and have to fold to a raise.

As played, I'm not sure how often he's bet/folding the turn given the remaining stacks. His strong made hands have to bet for protection and will mostly get it in, his strong draws will bet/gii, his weaker draws will check back. Weaker made hands might check back with the intention of calling a blank river. I don't think there's much two-barrelling with air on this board. So I just call the turn.

I agree with x/r flop as well

This is our board. Donk flop.

We donk flop for other reasons than just the fact it is "our board"

Good players (esp. when facing other good players) will have polarized c-betting strategies especially when short-stacked. That is, they will c-bet with hands they are quite happy to GII facing a raise and they will c-bet their bluffs & weak value/protection hands that are happy to fold to a x/r) - But they will check stuff like anything with a back door draw, 2nd/3rd nut flush draws with not much else, gutshots/pair+gutshots etc. since all of these hands hate to face a x/r and would be quite glad to see a free card.

When we x/r and GII with this hand against a polarized c-betting range we ofc will never be in terrible shape but we will also never be crushing opponent either (except vs 579T wrap with FD) - But on average I'd say we will have 40-45% equity.

Thus, our hand makes an excellent donking option since we want to be building a pot from all those hands that would check back (specifically the worse FD's)

Against your average villain at micro stakes though that will probably be c-bet quite high in HU pot and likely not be checking back medium draws, then we probably don't need a donking range theoretically and this hand is fine as a x/r or even as a x/c. But despite that, I still probably donk this hand as an unbalanced donking strategy.
