Database of every possible move in chess Imagine that there is a chess database of every possible move and position. This database contains all possible moves from opening to end game.

If I played using my intuition against a chess engine, it can predict which move will make me lose and win.

So this means there is no need for a "chess engine" because all of the possible moves are already recorded.

If such a database exists it would have the following advantages:


In fast blitz games, chess engine will definitely lose against chess possibility move database.
We can exactly know which opening will have more opportunity to win against the others.


Or if such a database didn't already exist we could have a mathematical calculation of all possible moves from opening till end game.

Would it be possible for such a database to exist?
I believe your question essentially boils down to the topic of whether it is possible to completely "solve" chess.  Wikipedia has an excellent article on the topic which should give you a good overview.

To summarise, the number of possible game variations in chess is estimated to be 10^120.  This is a staggeringly huge number, for comparison, consider that the number of atoms in the observable universe is estimated to be around 10^80.  In other words, if you were using the entire observable universe as your hard drive, you'd still need to store 10^40 combinations of chess games on each atom, in order to simply store it all.  Needless to say, this is so far beyond our current and forseeable technologies that most people consider it to be completely impossible.

Chess endgames are considerably less complex, and we've got to a point where it's possible to calculate all possible combinations for five-piece and six-piece endgames.  These are typically huge undertakings done by reasearchers with access to supercomputers, and the resulting endgame databases are huge (on the order of hundreds of terabytes).  Each time a new piece is added, the size and complexity of the calculations goes up exponentially, which means that in the forseeable future, we can expect these results to expand by only a few pieces.
