Time is money, or are you going to waste it?

Well, you can simply practice with bots for that. After a certain amount of training, many routine tasks start to be performed automatically. In addition, I believe it is wrong to be "doing your own thing" during your opponent's turn, as this way you waste not only your own time but also your opponent's time thinking about various things during your turn. I fully support the idea of chess clocks. Whether to allow the clock to tick during battle is a complex question. I am in favor of allowing it. If you really need a break to eat, smoke, drink coffee, or relax, nothing prevents you from agreeing on it with your opponent. When playing with chess clocks, it would be good to add a function for such a pause (naturally, by mutual agreement) - the timer does not tick for both players, and the interface for both is as it is during the opponent's turn - you can look at anything, but you cannot do anything. This function will be useful to refresh the map in your memory, which you saved last weekend.
