Showing the game to an audience: demo boards and broadcasting

Not every event does. Showing the game is worth the effort in four situations:

• There are spectators. A festival, a shopping centre, a corporate event - people who are not playing but are watching.
• There is a commentator. Commentary without a visible position is meaningless.
• You are teaching. A group cannot follow an explanation on a normal board.
• There is a final worth watching. The last game of an event, with everybody else already finished.

If none of those apply, skip it. A broadcast set up for nobody is effort that would have been better spent on the room - the logistics that actually matter.

A large vertical board hung on a wall with flat magnetic pieces, moved by hand in parallel with the game.

• Cheap and reliable. No power, no software, nothing to fail.
• Needs a person. Somebody has to move the pieces, and they must not make mistakes.
• Excellent for teaching. For a children's group it is not optional - a lesson without one does not work.
• Only one game at a time. And only for the people in the room.

Best for: teaching, simuls, a commentated final in a room of thirty people - equipment for a school.

The position is entered on a laptop and shown on a screen. In practice this usually means somebody replaying the moves into an analysis board.

• Venues often already have one. Co-working spaces, offices and conference rooms come with a screen, which makes this the cheapest route by far.
• Still needs an operator. The same job as moving demo pieces, only with a mouse.
• Room lighting matters. A projector in a bright hall shows nothing - check before promising it.
• It can show more than the position. Standings, pairings and the schedule between rounds, which is useful in itself.

Best for: corporate events and anywhere a screen already exists - corporate events.

Boards that read the pieces themselves and send the moves to a computer. No operator at all - the position appears by itself and can go straight online.

• The only genuinely automatic option. Which is why every serious broadcast uses them.
• Expensive. Each board is a substantial purchase, and you need special pieces and connecting hardware as well - what a set actually involves.
• Setup takes real time. Not something to attempt for the first time on the evening itself.
• Scales to several boards. Which none of the manual options do.

Best for: rated opens, federation events and anything broadcast to an audience outside the room. Rarely justified below that level.

A phone or camera mounted over the table, streaming the picture to a screen or online. The cheapest way to broadcast something rather than nothing.

• Almost free. A phone and a stand, or a tripod with a horizontal arm.
• Nobody has to operate it. Unlike a demo board or a projector.
• The picture is worse than it sounds. Hands cover the board, the angle distorts the squares, and the pieces are hard to read at a distance.
• Lighting decides everything. Overhead light throws the players' shadows straight onto the board.

Best for: an online stream where a commentator explains what is happening, and as a backup record of the final game - material for coverage.

And the thing that matters more than the equipment: a commentator. A position on a screen with nobody explaining it holds an audience for about two minutes. One person saying out loud what is happening turns the same picture into an event.
