I should add that instead of re8 instantly(a mistake) you should add in h6 first, either forcing a capture(getting rid of the pin) or making the bishop go to h4 where the h4-h5 attack will then be delayed. perhaps a regrouping will work then.
I still think white holds an advantage with c5 after h6 bh4 re8 c5. A long term one with structural superiority due to the weakness of the d pawn.
So yeah, the move you suggested, re8, was even worse of a mistake than bxc4 was.
Spoken like a true Russian.
