Hi GP, Hi RB

The first thing that caught my attention was the second c5 by black on move 27... its a free pawn as the knight is on a dark square and black has no immediate way to chase it off. The threat of the c pawn will draw the rook to the c file whence the queen can infiltrate e7 via c5 with ideas of mate.

If black does his best to keep the pawn from advancing this could happen
