Souvent de langues différentes, ces théoriciens n'ont pas pris grand soin à unifier la terminologie, et on retrouve parfois le même terme dans des acceptions totalement différentes selon les auteurs. À l'ère du tout informatique et des tables de finales, ces théories présentent cependant l'intérêt d'être compréhensibles et utilisables par un être humain. Le concept de case-clé, base commune à plusieurs de ces théories, est fondamental pour la compréhension des finales de pions. Chaque pion possède son propre système de cases-clés, qui est modifié à chaque mouvement du pion. Pour compliquer encore les choses, Maizelis appelle « cases critiques » ce que Youri Averbakh nomme « cases-clés »[3]. Le concept de « case critique » existe également chez Averbakh[5], mais dans un sens plus précis et assez différent. Il faut aussi remarquer que les cases-clés apparaissent dans d'autres finales plus complexes que l'élémentaire Roi et pion contre roi seul.

How to win Rock-paper-scissors every time I admit it. When I first heard there are actual tournaments for Rock-paper-scissors, sanctioned by the World Rock Paper Scissors Society, I laughed. I mean seriously, $50k to the winner of a game that requires no skill whatsoever? Rock-paper-scissors isn't just a silly game kids play or a way to decide who has to be the designated driver at parties. Males have a tendency to throw rock on their first try, inexperienced RPS players will subconsciously deliver the item that won previously, and paper is thrown least often, so use it as a surprise.

Chess Problems News: Old chess problem books have recently become much easier to access, thanks to Google Books and similar services, as well as Kessinger and other reprint publishers. Some time ago I discovered that the Mackenzie title I was working on was available on Google books, and as it seemed doubtful if a new edition would be of any additional value, my work on it grew more and more fitful, and gradually ceased: today I have dropped it entirely. This means that I will probably not add any new titles to the list below, unless I am convinced that such addition would be useful, even if there are other sources for it. American Chess-Nuts will remain a bit longer -- I might still finish it. I would like to pass on a word of warning to those who decide to purchase reprint edition: if you do, be sure to verify pagination carefully when you receive the book.
