Cucumber Style?

Global regular-expressions

Unmaintainable large step-definition files

Flexibility

Coverage vs. Speed tradeoffsComplex regular-expressions are hard to read

Feature

In order to prevent invalid moves

As a GoVsGO website member

I want the rules of Go enforced.

The Rules of Go

Capture After playing his stone a player removes from the board any stones of his opponent's colour that have no liberties.

SuicideA player cannot place a stone that would result in the capture of their own stones

KoOne may not play in such a way as to recreate the board position following one's previous move

Ending The game ends when both players have passed consecutively
