The Best Move in Chess?
Obviously, it's entirely dependent on the situation. This idea is for curiosity's sake only.
But, if it's not been done before, I think it would be interesting to run a database of GM games through computer analysis. Compare the evaluation before a move with after it and take the difference.
Then take the average value for every individual move. So all the times e4 has been played (not just as a first move). All the times Nf6 has been played. And so on.
What do you think would work out to be the 'best' move?
In reality, I think the system would give us the least bad move as the computer analysis would punish bad play much more than reward good play. Nevertheless:
Promotions would rarely be bad moves, but that's obvious.
Nf3 is good in a huge number of situations. cxd4 is often quite good. Bg7?
Anyone have the power to put this together or care to take a guess at a 'best' move?
