Gomoku/Talk

What does the following paragraph in article mean

Beyond the most rank beginner ability, making two intersecting runs of three stones (each line open at each end), which is an automatic win for the player who makes the two lines, is illegal.

Which move is illegal?

Winning against me :-). Seriously, hope the rewrite helps. -- NickelKnowledge

Not really. Who says it's illegal? What defines "the most rank beginner ability"? How is it invalid? How do the rules enforce this? This could possibly be an opportunity for a formal exposition of the rule set you're using, similar to several of the other board game entries. Please take care to cite whose rules they are (is there some national or international association for this game?), since the rule you're expressing is clearly not universally-acknowledged (nor even universally-known -- I've certainly never heard this one). Care to take the challenge? -- Bignose

I think it is a universal rule, but it is usually not given to beginners. After a while, beginners realize that the game is pointless, because Black can force a win, and then they're given the additional rule. I doubt that there are "official" Gomoku rules or organizations; the closest serious game is Renju?. --AxelBoldt
