Do you think that "Never let your opponent know your next move" is reasonable advice? It's complete nonsense.
Besides, the guy is a known troll who was banned for trolling. But of course, on this website banned trolls can come back with another account and continue trolling, and the moderators do nothing.
if you actually didn't let your opponent know your next move, they wouldn't premove and make you lose time. And you would have a higher rating. "Never let the opponent know your next move" makes complete sense and is not dumb. It is a basic way of thinking. Or, you could say, Never let your opponent know your plan. Its basically the same. Magipi, now you're sounding like a troller.
What are you talking about, dude? What you say is also complete nonsense.
How could the opponent know my next move? Even I don't know my next move because it depends on what the opponent moves first.
Also, how could your opponent know your next move? With telepathy? And how could you stop that? These things have nothing to do with chess.
I am far from 2000 but I usually suggest to win more and to lose less if you want to increase your rating, it should work for any initial rating
