First off, this flop creates a standard Way ahead/Way behind situation. Normally, WA/WB applies when there's only 2 people, but this is such a clear cut flop that the principles probably still apply. In a WA/WB, you want to call bets on the flop and turn and generally bet out the river and fold to a raise.

Normally, I'd check/call the flop since a whiff isn't especially bad for you (only an A or a 6 are bad for you). A bet doesn't particularly buy you anything since only a K or a pair is calling you (no draws) and, statistically speaking, probably no one else has a pair.

However...you have reads that at least 2 people are going to play. It's unlikely anybody's going to raise the flop with a king (they'll wait for the turn) so you might want to bet and possibly collect a bet or two from people drawing nearly dead. If you do get raised, you can revert back to WA/WB strategy.
