Not horrible:

Code:
Board: Qh 6h 6c
	equity 	win 	tie 	      pots won 	pots tied	
Hand 0: 	53.841%  	51.19% 	02.65% 	         54732 	     2835.00   { JJ+, AKs }
Hand 1: 	46.159%  	43.51% 	02.65% 	         46518 	     2835.00   { KK }
Interestingly, we are actually in better shape against this range with an A on the board instead of a Q or a J (because it's a blocker for AA, mostly):

Code:
Board: Ah 6h 6c
	equity 	win 	tie 	      pots won 	pots tied	
Hand 0: 	34.532%  	31.55% 	02.98% 	         32796 	     3100.50   { JJ+, AKs }
Hand 1: 	65.468%  	62.48% 	02.98% 	         64953 	     3100.50   { KK }
Also, even if we change the range a bit, we're still not in great shape, especially if he's not going to c-bet so huge with a bricked AK:

Code:
Board: Qh 6h 6c
	equity 	win 	tie 	      pots won 	pots tied	
Hand 0: 	56.035%  	53.38% 	02.65% 	         57078 	     2835.00   { QQ+, AKs, AKo }
Hand 1: 	43.965%  	41.31% 	02.65% 	         44172 	     2835.00   { KK }
Then again, is he going to bet so huge with QQQ? This hand is pretty read-dependent IMO, but I don't hate the fold.
