Floped set with KK! Now why am I so dumb?

[Grendel]

Still stinging from my last session in which I flopped sets with AA, KK, QQ, and lost all three. But let's get down to business here.

UTG+1 is super-loose and raises a lot, kind of like Bill Clinton on Viagra. MP1 is tight/agressive.

Final Pot: 14.25 BB

With the flop call I was hoping MP1 would raise... Foolish?

Now what about that river?

Thanks in advance,
