Also cheating discussions are best for the cheating forums as they are not allowed in general forums

* Basically cheaters are programs
* They continually pursue the target - you - inflicting one defeat after other the most absurds. knowing in advance all your moves and even predicting your lines entirely
* You block, denounce. Then you search for another game: comes other. Until they decide it's time for the "good cheater" that easy program that let you win without any effort.
* 10 defeats in a row no matter the best you play. Then 10 wins in a row even if you play watching TV
