...grunch...

I'm not a big fan of coldcalling preflop with KQo. If he really is laggy and has been showing that he's raising with junk, I'd 3-bet to try and isolate.

Slowplaying the flop is fine, let the others peel.

I'm also not a big fan of waiting for the river to raise. If you thought there was a good chance the others might peel again then maybe, but having MP1 check the river would suck.
