This was not the font in which I found the game, I´ll give it when sure,
but in it the author says that this game was wrongly allegated to be
played by the Einstein´s son, but Hans never played Chess, and he says the
game was played by Albert against James Robert Oppenheimer in Princeton,
1933. The oscure aspect in this information is the game itself and
circumstances. It is an annotated game, and it sounds, at least,
unexpected. On the other hand, Albert Einstein once said he feel
'repugnance' by the 'agressive spirit' of this 'war game' in which
'the mind is used to surrender the adversary'. Nevertheless, there is
some evidence that Albert Einstein played Chess against Edward Lasker a
few times (I have read about it, let me find the article), if it is the
case, I doubt Einstein played the annotated game against Oppenheimer (the
annotated game is a game beteween novices, regardless some good moves by
'Einstein'), because Lasker was a high level player, and I doubt both
of them want lose time playing a game between players with very different
strong forces, more knowing the concept about this game Einstein had, and
knowing some facts about Lasker´s personality. I have doubts whether this
game was played by Einstein, his son, Oppenheimer, or none of them.
