premove ?

Hi, I've sometimes read about premoves.

What is it exactly, and how tu use them ?

Thanks !

And here's the article:

Aha, thank you very much !

A premove is when you move before your opponent has made his move, and your move will be made automatically immidiately after the opponent makes his. If the move is not legal after the opponents move, no move will be made. 

To enable premove you have to go to Home and Account, and then press "Live chess settings". And there it is. In a game you simply play a move when  it is your opponent´s turn, and the move will be made after he moves

Ok, thanks. I guess it might be hazardous if, for instance, he plays an attacking move that you haven't foresight :-o
