What Is Simultaneous Chess?
In simultaneous chess, one player faces multiple opponents during a single event. The boards are usually set up around a room, with the exhibition player walking from one board to another.
The opponents stay at their boards and make their moves when the exhibitor comes back around.
It is not normally about speed. The interesting part is the mental workload on the player giving the simul. They might have ten games going on, or fifty, with every position requiring a different plan. The event can be organised by anyone from a club to a tournament, or it can also be an aspect of a larger promotional or community event.
How a Simultaneous Exhibition Works
The rules follow the same as a “normal” chess game, but the format can vary depending on the event.
The exhibitor makes the first move, then moves around the room to the different boards. Each player makes their reply when the exhibitor reaches their board. Then the exhibitor moves on again.
For the person playing against the master or grandmaster, there is an unusual advantage: you can sit with your position for quite a while before they return.
The other side of that is that your opponent may have looked at your position only seconds earlier and still find the move they want.
There is also a bit of etiquette involved. Players should be ready when the exhibitor arrives at their board, and normal rules such as touch-move may apply.
Famous Simultaneous Chess Records
Some exhibitions have grown far beyond the size of an ordinary club event. Top players have taken on hundreds of opponents, making these displays as much a test of stamina and concentration as chess ability.
Records have changed over the years, but the idea remains the same: one player trying to keep track of a remarkable number of games without losing the thread of any of them.
That is probably what makes simultaneous chess so entertaining to watch. You are not just seeing a strong player calculate moves. You are watching them switch between completely different positions over and over again.
Conclusion
Simultaneous chess is part chess match, part endurance test and, for the people taking part, a pretty memorable experience.
You may not beat the grandmaster. Most players won't. But getting the chance to sit across from a titled player, make your own moves and see how they handle your ideas can teach you a lot.
And if you do manage to win one of those boards, you will probably be talking about it for a very long time.
