I think that this flop favors the caller and my particular holding makes a good x/c candidate with double belly buster plus two overcards. Turn is good for my holding, however, not for my entire range I guess. I have something more than pot left - jaming might look to strong, so I decided to donk small and jam river. This particular river seems pretty bad tho, since Villain's sets improve to full houses and I am probably still behind against KQ. I dont know what to make of it, jam, x/c, x/f all seem reasonable.
Yes. Obviously best strat is mixing almost everything to 50%. I think we can play easily without mixing flop strat, losing not so much ev; and checking range in 2tone flop like that. But it's up to you.
