TP no kicker + BDFD, call flop?

[Ampelmann]

I haven't played many hands, but the table seemed pretty loose (this hand is an indication for that). The only player I know to be somewhat decent is the CO (and he folds anyway).

I have TP, great. It's not impossible that someone has me outkicked (4.5 outs for me) and that someone has a straight (1.5 outs) or several might be on straight draws (bad reverse implied odds). Even if I have the best hand and nobody has a OESD, many overcards can come (bad reverse implied odds). However, the pot is huge (12 SB) and I close the action.

Without the backdoor draw I think I'd fold, but here?
