TPNFD in 3 way pot, standard?

[Requin]

These guys had been playing HU on this table just a few minutes ago. No reads on them, except for a very vague feeling that I'd played BB before and that he was bad. I was pretty unsure of this read though. Comments on all streets please, although I know PF is probably too loose.
