I completely agree with pocketfours

- this is range I think he can has (or something similiar)

Board: 4d 5d Th
Dead:

equity win tie pots won pots tied
Hand 0: 27.421% 27.42% 00.00% 4615 0.00 { Qd9d }
Hand 1: 72.579% 72.58% 00.00% 12215 0.00 { TcTd, TcTs, TdTs, 55-44, AdJd, AdTd, Ad8d, Ad3d, Ad2d, KdTd, 8d7d, 7d6d }

- we have exactly 3:1 to call and against my range we have something like 2,6:1
- but I still think this is fold, because I'm not sure, that 100NL reg is good enough in poker to play this hand profitably vs this range OOP, w/o initiative
