SB: unknown

Flop cbetting is pretty std in this texture so I gave him a range like:  AT+ K9s+ KJ+ 99+ SC-s: 67s 78s 89s T9s JTs JQs

The majority of his pre 3betting range is became worthless OTT, so I thught it's time to valuebet against 77, 99, T9, 67s type hands. 

River is so sick... my first thought was that it's a weird line with a Qx type hand, or a blocking bet from 99-JJ. 

I fold because villain is an unknown player, and I couldn't certainly realized what's going on...
