Did you ever notice that things tend to come around again in different disguises? The same old, same old all dressed up in different clothes. So-called unfair advantages in chess wear many costumes but, in the end, it is still a protest about those alleged advantages. Check this out:

Two-Dimensional Boards in a Three-Dimensional World

Those digital notation devices were game changers for OTB chess. No more illegible scribbles on paper scoresheets. Games could be broadcast live on the internet. Tournament game bulletins went from tediously entering moves to point-and-click data transfers. But like anything new, those devices came with some baggage.

Many pragmatic wood pushers soon discovered a valuable and unintended notation device assetthey could preview the intended move on their two-dimensional gizmo, before they actually had to make their move on the three-dimensional game board. The outcry from the troops did not go unnoticed. The rule giversthe delegatesdictated that moves had to be made on the game board before they were entered into those note-taking gadgets. While the outcries died down somewhat, a new protest arose.

The new argument claimed unfairness that device-users could analyze their exact three-dimensional positions on a two-dimensional screen. But the counter-argument to this pointed to the widespread use of top game demonstration boards that already allowed players to evaluate their own current games in 2D. Some devices featured the ability to project games onto large screens, which have become the replacement for those old-style demo boards. This improvement allowed the top contests in each section to be viewed by everyoneeven the two players.

There was no evidence that players analyzing their own games, be it on demo boards or two-dimensional screen projections, provided any advantage whatsoever. The law-givers passed no regulation governing this activity: Wood pushers analyzing their games on a two-dimensional replica of their current three-dimension contests were not banned. (An individual organizer might ban this activity, though, so checking that events special tournament rules was always a good idea).

Three-Dimensional Boards in a Two-Dimensional World

The pandemic replaced OTB chess with digital chess. Online platforms replaced onsite tournament halls. Three-dimensional chess boards were replaced by two-dimensional replicas. The rulebook updated Internet Chapter 10 with new regulations. Now the question from some contestants is: Can I use my 3D set and board next to my 2D online board?

Ironically, these days I hear rumblings about the physical board next to its digital cousin as an alleged unfair advantage -- but the 2D equipment is the standard. Its the same old, same old alleged unfairness in a change of clothes: the same thing, only different!

There is no specific language that allows or disallows a 3D sideboard. The closest the US Chess rulebook comes to addressing this 3D question is in chapter 10, rule 6A, which points out that organizers in this new online era can create online event specific rulesjust like they are able to do for OTB tournaments. FIDE recently published their own set of online rules that addresses the extra 3D board subject.

If having that extra third dimension set-up for US Chess events concerns you (one way or the other), check with the organizer before you sign up for their online tournaments. And, of course, be prepared to move your troops first on the 2D board before they do any marching on your 3D boardthe camera will know!
