The Stonewall

The Stonewall structure carries many clues for the fight that will ensue. Here's the basic diagram:

StoneWall pawn structure

For white, the fixed pawns on d4, e3, and f4 mean that white's dark-squared bishop will be "bad." It will have far less scope than white's light-squared bishop. A bishop on d2, for example, would be relatively inactive. By contrast, a Bishop on e2 would have many options.

And for white, the knights belong clearly on e5 and f3 or d3.

Black's light squared bishop would be the bad bishop, and so black would like to try to trade it off. The usual method is Bc8-d7-e8-h5. But in the following game, I managed to trade it off it two moves, not four.

I have also included about 100 games using this structure in which black also wins by playing Rg8 and g7-g5. Enjoy.
