The shape game (solid wall version)

White to move and make a living group. Black to prevent that.


Teaching value

This shows the great power of walls even if they are all the way across the board from the invasion stone.

Expected result

The result of perfect play is not known. Practical tests show it's somewhat balanced with some people saying it's easier for white to live and others saying it's easier for black to kill.

Comparison to ShapeGame

This version removes a lot of confusing side-issues about what happens when white peeps at the side jumps.

Comments

MrTenuki: Why not remove the four stones from the corners, so that Black's group becomes a two-headed dragon? As things now stand, there is a slim chance that White could kill Black's first-line group...
