The tale of cracked Kings. Party $25NL

[TheSeeker03]

Party. Blinds .1/0.25. All stacks about $25.

I am in MP with KK, raise to 1.5, get two EP callers. Pot is ~4.5. Flop comes 345 two diamonds. Villain bets 3, Villain2 calls 3, I min-raise to 6, they both call. Pot ~22.5

Turn comes a 7. Villain is all in for about $13. Villain2 folds. I thought, no way would he call PF raise with a 6, and called. He had 66 and won with a straight.

There are probably many things I did wrong here ...
