Still about a little Go change

[check previous] What should happen around the edges? Should pushes be allowed? The rule can be restated as: "If an isolated piece is in atari, the other player may push it into that empty cell."

This means that the next move would be possible:

  . . . .       . . . .
  . x o .       . x o .
  x . x o       x x o <
  [edge]        [edge]

This rule still has the effect of eventually create new eyes and more KO problems. One way to solve that is to state the rule like this: "If an isolated piece is in atari, the other player may push it into that empty cell, placing a new stone on that cell".

The previous move would result on the next position:

  . . . . .
  . x o .
  x x o o
  [edge]
