I have 100% wins with black in Gomoku. It is not normal. Do not change the rules to swap 2. This would attract a large number of players. I think that if you do not change the rules is half the players go away from this site, it's very disappointing. Please make SWAP 2.
It was long time ago, back in 2005-06, but I won four times against Anatolij and one of them was with white. István Virág (who is, as I have heard, one of the best players in the world) also defeated Anatolij with white several times. So there was a time when it was not impossible to win against Anatolij with white.
Nevertheless, Anatolij's proposal makes perfect sense, if Swap2 is implemented then I might actually resume playing Gomoku.
