Why check the flop? Are you trying to check-raise? Lassesh acts like he was slowplaying something, although he could also be a monkey with pocket kings. To me though it comes off like he flopped a set. That check from last position after he raised pre-flop is baffling unless he either has no hand at all, or a monster, or a high pair like kings or queens.
