Body: <p>I've noticed a distinct difference in the premove system between Lichess and Chess.com. Lichess allows only one premove at a time, whereas Chess.com permits multiple premoves. What is the rationale behind this difference in design? Does it significantly affect the strategy or pace of online chess games?</p>
