The idea stems from something far less theoretical than a teaching method: playing blitz with friends. The problem was that we always ended up playing the same openings, those from our own repertoire, game after game. Predictable, and after a while, less fun too.

The solution was a deck of cards with dozens of different openings: instead of choosing what to play, you draw a card and play that. It completely changed the way we play blitz among friends, making it much more unpredictable and fun.

From there, the idea was born to extend the same principle to other phases of the game: gambits, middlegame positions, endgames, tactical puzzles. For each deck, you draw and play, in training or simply for fun among friends.
