Mbob, thanks for the reply. But, are you saying to raise here?

This is dangerous flop for me given the size of the field. I could be up against a flush already. 1/3rd of the time a very likely flush draw will fill up. There are also possible straight draws on this hand. And my kicker isn't great, I could be outkicked or up against two pair or a set. Any spade and any card 7 or higher (other than the two remaining Jacks could be bad for me). I don't know if this is being to paranoid, but against such a large field I think it's warranted.

I'm torn here between 1) folding, 2) calling to the river if no scare cards come and I don't face any heavy action, and 3) calling the flop & if I get a safe card on the turn, bet out.

Folding vs. calling down I believe comes down to my estimate that I'll have the winning hand at showdown vs the expected odds. I think the expected odds are around 4-1 in this hand. So I need to think I have the best hand at the showdown at least 20% of the time. Not sure that's the case.

Waiting for a safe card on the turn and betting out doesn't seem bad. But what if I'm raised by an opponent that I have seen bluff? And what about the others who may be slow playing a big hand. Betting out on the turn will be me in a difficult spot if I'm raised.

I really don't know on this hand, comments are appreciated.
