Pour ce faire, pouvez-vous écrire dans les commentaires les moments clés où il vous semble que la partie bascule. Cela permettra de confronter votre ressenti avec celui de votre adversaire, mais aussi celui de l'IA.\n\nPS : Selon les pédagogues, l'IA ne doit-être utilisée que pour confirmer ou infirmer une intuition. Il est préférable de ne pas prêter attention aux autres coups sauf grosse erreur que l'on n'aurait pas détectée soit-même.\n\nBon tournoi !",
