!?

It’s said there are more books about chess than all other games combined.

To non-players, a chess book is an arcane mystery of jumbled letters and references to openings with such exotic names as the Nimzo-Indian Defence, the Nescafé Frappé Attack, and the Sicilian Najdorf Poisoned Pawn Variation.

But notation is deceptively simple. Each move simply lists the moving piece and the co-ordinates of its destination. Be4 is a bishop move to a central square. Rxa8 tells us the rook is capturing whatever’s in the top-left corner.

So far, so functional. However, chess notation also provides means of passing judgment on the moves. Expert annotators earn their living by peppering games with punctational shorthand:

• ! – good move
• !! – excellent move
• ? – bad move
• ?? – terrible move

These symbols can be combined. ?! denotes a dubious, but not awful, move. !? is used to mark an novel idea that looks promising but may prove to be unsound.

It’s the !? moves that I’m most interested in.
