Confusing line and tough spot that you very rarely see at 25nl and below - are 50nl regs normally nutted when they take this line?

Turn looks like a call despite the fact we'll probably want to puke on the river. Worst-case scenario imo gives us 17% equity and makes calling tight but okay as long as we can extract some extra $:

Board: 2c Ts Td 6d
Dead:

equity win tie pots won pots tied
Hand 0: 17.208% 10.23% 06.98% 63 43.00 { Th9h }
Hand 1: 82.792% 75.81% 06.98% 467 43.00 { 66, 22, ATs, KTs, QTs, JTs, T9s, ATo }

And if we factor in some flush draws with overs and middle pp then we're certainly doing well enough to call.
