Club championship of the CIS countries.

Generally, the idea is that when there's enough time, players usually don't think about the opponent's move while it's happening; instead, they focus on their own. This means that roughly half the time is wasted. This contributes to the drawn-out nature of many tournaments. To make the waiting time for the opponent's move more productive, here are some possible solutions: 1) Strict time control (so that there isn't enough time to think during one's own turn, only enough to execute the planned move). 2) Playing two games simultaneously. The first option is more challenging for players (especially those who enjoy a drink), so it's often rejected. The second option is more user-friendly (for many reasons).
