user25317: I am thinking on a way, most ideally on a software tool, what could get one of more games of a player, analise them, and gives an estimate on his play strength (as Elo/Glicko rating).
Is it possible? Does such a tool exist?

user15223: Yes it's possible. Sort of. It's one way people have compared the top players throughout history. The basic idea is that you feed the engine the position and the moves played by the players, and see how probable it is for them to play the computer's best move.
I don't know any ready-to-use program for this kind of analysis, however.
