The hands you have to be worried about are KQ, KJ, AJ, and AQ

If that is his range then your equity is:

Board: Qs Jc 6c
Dead:

equity win tie pots won pots tied
Hand 0: 26.695% 26.13% 00.57% 9312 202.00 { AdKd }
Hand 1: 73.305% 72.74% 00.57% 25924 202.00 { AQs-AJs, KJs+, AQo-AJo, KJo+ }

If he has a hand like TT-77, 66-22, then your equity is:

Board: Qs Jc 6c
Dead:

equity win tie pots won pots tied
Hand 0: 38.100% 38.10% 00.00% 18105 0.00 { AdKd }
Hand 1: 61.900% 61.90% 00.00% 29415 0.00 { TT-77, 55-22 }

There is $167.50 in the pot and it is $75 to call, so you need about 31% equity to make the call breakeven.

You are right, it is very close. If he has TT-88, then a fold is a mistake. If he has one of your out counterfitted, then a call is slightly bad.

If we merge the two ranges, and maybe throw in some hands like JT and QT, we are:

Board: Qs Jc 6c
Dead:

equity win tie pots won pots tied
Hand 0: 32.714% 32.53% 00.19% 34776 202.00 { AdKd }
Hand 1: 67.286% 67.10% 00.19% 71740 202.00 { TT-77, 55-22, AQs-AJs, KJs+, QTs, JTs, AQo-AJo, KJo+, QTo, JTo }

So as you probably guessed. It looks like it doesn't matter what you do. Call and fold both look break even to me.
