Hand 1: I sim'ed as:
36% equity vs 2 flushes OR 1 flush and 1 f/d
30% equity vs 1 flush and AoKd

$98.55 to win $263.05, 2.65:1 easy call assuming that there is < 25% chance or so someone has a higher set... also they might both have f/d or pair no draw!

Hand 4... only hand UTG realisitically has that beats you is TT/99/QQ, no? AA/KK re-re raise, no? I am more worried about button. This might be a nice sandwich, but I think you have to raise more to get Button to fold an overpair. Which he probably doesn't do.
