Introduction:
Quality of your original gomoku algorithm can be proven by competition with other developers. The Pixoria is an ideal environment for competition of different solution.
from developer labs:
FREE SECTOR FS05 (AXONYA)
Developer added new code: "M+" and "best end" rules. Therefore this engine play very good. Rating is 840.
FREE SECTOR FS03
Developer added new code: "more delays" and "prediction" rules. Therefore this engine play very good.
FREE SECTOR FS01, FS02
This developer modified source code iM007 engine. Cutaway and simlified him. Something is here improved and something new added...
IN-MACHINE 007
Next interesting engine by independent developer. How works this engine? How rules he use? How make of source code? What is it compulsory move?

IN-MACHINE 004, 005, 006
These engines they are realy good. Beat all lowest and some highest
(APPENDIX) MC Soft engines without necessity changes in their strategy
configuration. Congratulation to author and thanks for source codes. Source files contains also very useful images with schemes and rules (click here to see)
. Graphics to engines delivered JS.
The best gomoku engine you can try now is:
PIXORIA STEP 33
its author is: Marek CichoĊ
(on of 19 engines in PIXORIA APPENDIX)
Of course there are better solutions. Our platform is open to all gomoku coders. We look forvard to your superior engines, their interest strategie, original algorithms and sophisticated heuristics. What has to fulfill any Pixoria engine?

hints:
The move of engine IN MACHINE 000 in the diagonal is solved this way (see source code in C++):

Have you better idea?
