NL10: Was I insane to shove here?

[Snozynoze]

The call preflop is fine against a true crazy player (40/15 doesn't mean he's raising any two though, his raising range is much tighter)

Againts a 40/15, i'm looking to be the one raising preflop, as that means he's calling with almost half the deck.

But we are here on the flop, and this is a good flop....so build the pot.

If you get coolered, that's the way it goes. Playing KQ, you might get shown AK. This many people, you might get shown K5 too. It happens.

Build the pot. It's multiway, get in a bet. You will start building a pot when ahead as well as learning information for the streets to come.

From your river shove, i can see you planned all along to get it in, so don't play scared on the flop and turn, and don't play tricky. The kings will call, as well as players that think, "Well if he had a king, he'd check here."
