The flop is very dry. So probably only a K or a set will call. If noone has one, the pot is probably yours, because you represented a hand like AK, AA, KK preflop (unless they are cynics and just don't believe you). The problem is that it's not HU and Button showed strength before the flop and UTG came along. So there are quite some Ks in Button's range: AK, KK, KQ, KJs, KTs or any suited K maybe. Add some PPs that he might call with because he thinks you don't have a K. Quite the same is true for UTG, although I would tend to put him more on something suited or a pair. Therefore your cbet doesn't win this reraised pot against 2 players often enough, probably. Check and see what happens.

Turn card didn't really change anything. So if you think that UTG is actually weak, stick with your read and call. If you think he is sucking you in, then fold.
