Exactly Dmitri. Other sites have pente, WITH the restriction and nobody is shouting there saying they demand it without. Its the rules, IYT seems to have messed everything up, and if I'd have seen 'pente' or 'pro pente' here I'd have gone for pente because I didn't know how to play the game!!
Imagine then if I'd have entered a tournament WITH the restriction! I'd have been slaughtered!!
As I said before, rules are rules!!
