The number of possible, unique chess games is far greater than the number of electrons in the universe! The number of electrons is estimated to be a mere 1079, while the number of unique chess games is 10120. In English, that's a thousand trillion, trillion, trillion, trillion, trillion, trillion, trillion, trillion, trillion games.
Now isn't that interesting?????????

jvila,
Forgive me for my ignorance,
But what exactly is 960 chess modality?????

it is basically an altered chess game to steer the game away from opening theory and make the game only strategy based. The pieces on each player's back rank are randomly placed. There are 960 possibilities, or something..
