Checked pocket jacks preflop in BB, agree or disagree?

[sfetaz]

Yesterday I was playing 3/6 hold em at Taj Majal in Atlantic City. As usual the table was filled with a bunch of donkey maniacs. In this particular hand 6 other people called the BB and I look down and saw pocket jacks. The natural instinct is to raise, however I very quickly said this in my head and checked: There are 6 other people in this pot who are all capable of having almost any two cards. It is very reasonable to assume an A K and Q are all in people hands. If I raise no one will fold for a fact. The odds of an A K or Q flopping is over 60% (correct me if wrong). Even if no A K or Q flops, without a jack and the maniac play these people do, I have no way of knowing if my JJ is good at that point unless I flop a set. Finally, if I do raise, with all the callers, any form of reasonable draws on the flop are now getting a great price to stay in. And at this table, you have players capping the pot preflop with ace 10 and calling to the river with absolute nothing until their ace rivers and cracks my kings. So I checked. An ace flopped, there was bets and callers and I folded my jacks. The original post flop better did have the ace. Do you agree with the notion of saving the extra 3 dollars there?
