I ask me, which is the "true" Tiger? When the true Tiger is with option Anti-Human, then i my opinion it is not right to say: Anti-Human! Right is "Anti-Computer"! (german: Ich frage mich welcher nun der wahre Tiger ist, der mit der Option Anti-Human oder der ohne diese Option? Wenn insgesamt jener Tiger mit der Option Anti-Human besser spielt, dann sollte man diese ANTI-Option anders definieren, nämlich auf "Anti-Computer"! Das würde aber weiter heissen dass der wahre Tiger nur gegen den Menschen auftritt, während gegen Computer eine auf Computer "GETUNTE" (!) Version antritt und ich würde das wenn's so ist (?) "Schummeln" nennen! Dennoch vermag diese Anti-Human option den schwarzen Sieg nach Be3 nicht zu sehen.) Nevertheless, Tiger 14 with option "Anti-Numan" cannot seen the win for black against Be3!
