I don't know if it's right, but I'm never folding here. Tons of LPs will limp their entire range, so villain's range might be something like most TP+, all 2p+, all pair+FD, all pair+SD, all SD+FD, all OESD, and all nut FD (could be even wider). This would look something like this:
{AA, KdKs, JdJh, JdJs, JhJs, 9s9c, AQs, ATs, QTs, T8s, 87s, AdKd, AsKs, KdQd, KsQs, KdJd, KsJs, QdJd, QhJh, QsJs, KdTd, KsTs, JdTd, JhTh, JsTs, Ac9c, Ks9s, Qs9s, Qc9c, Js9s, Ts9s, Tc9c, Ac8c, Qc8c, 9s8s, 9c8c, Ac7c, Qc7c, Ac6c, Qc6c, Ac5c, Qc5c, Ac4c, Qc4c, Ac3c, Ac2c, AQo, ATo, QTo, AdKs, AhKd, AhKs, AsKd, AcKd, AcKs, KdQh, KdQs, KdQc, KsQd, KsQh, KsQc, KdJh, KdJs, KsJd, KsJh, KdTh, KdTs, KdTc, KsTd, KsTh, KsTc, Kd9s, Kd9c, Ks9c, QdJh, QdJs, QhJd, QhJs, QsJd, QsJh, QcJd, QcJh, QcJs, JdTh, JdTs, JdTc, JhTd, JhTs, JhTc, JsTd, JsTh, JsTc, Jd9s, Jd9c, Jh9s, Jh9c, Js9c, Td9s, Td9c, Th9s, Th9c, Ts9c, Tc9s}
Against this range we have 62% equity. Villain might have even more FDs than this, like KXs and QXs.
I happily c/c down to the river here I think, unless particularly scary cards pop up and villain shoves.
