Good advice.

 i am not pro  buh for the most part i play pro gomoku type openings ....i dont play for the first two open 3's
  the reason for that is 2 2open3's was only worth a 1/2 point in the game of 5's and..you cannot win with 2 open3's
AND you have to play AWAY  if you do make 2 open3's  ...it is somewhat like Renju  somewhat like gomoku...i like the rules of that game better than renju or gomoku somewhat more of a challange to play for a win

 

Well only way to beat good/best players is through observing others higher then your on rating, and through experience of course. :)

It's been proven that under perfect game circumstances, first player always win. Therefore the game is a chance of who goes first, and not on skill.... once your at a certain level ofcourse.... but I can almost always get double threes (the always winning combo for going first). Its too easy

I think there is no easy way to become GM.
You need to play a lot of serious real-life games
or at such servers as

At least two times WRL Meijin did so:

And in my opinion Gomoku and Renju are one game.
Russians even use the word "Renju" for Gomoku too.
If you strong at Renju you will play Gomoku fine.

Beat every1 I would add as well. I simply take just about any challenge I get...
