Emanuel Lasker and Psychology I have heard many people saying that Lasker used psychology to win. But I have also read a Wikipedia page mentioning recent researches refuting this belief and justifying Lasker's tactics to be quite ahead of his time and something laden with a hidden master plan. I need to know if there exists any such analysis which is available online so that we can know the truth ?
We can't know the truth. Lasker is dead and he's the only one who knows if he really played like that intentionally. We can create an absolutely perfect analysis of his games and still never know if he intentionally played a bad move that happened to work out in a particular game or whether he just made a mistake and didn't get punished for it.

Good moves will beat psychology every time, but even so there exists ample evidence to support the idea that sometimes moves that are less than perfect will win games because they fit in with the psychological moment.

My own opinion? I think Reti invented that as an excuse to cover the fact Lasker was making moves he (Reti) couldn't fathom. Not that Lasker never played the man instead of the board, but that he didn't do it as often as Reti would like us to think he did.
