The Clemenz Opening is a chess opening described in algebraic chess notation as

1. h3

It is named after Hermann Clemenz (1846–1908), an Estonian player. It is considered an irregular opening, so it is classified under the A00 code in the Encyclopaedia of Chess Openings.

Like Anderssen's Opening, 1.a3, 1.h3 is a time-wasting move, as it makes no claim on the central squares, nor does it aid development. It also leads to a slight weakening of the king's side, albeit not as severely as Grob's Attack, 1.g4, or Barnes Opening, 1.f3. Since there is no need for White to make such a time-wasting move on the first move, it is among the rarest of the 20 possible first moves. Nevertheless, Michael Basman has experimented with 1.h3, usually following it up with 2.g4 (transposing to the Grob), or 2.a3 followed by a quick c4, a line which has been dubbed the "Creepy Crawly".

Black has a number of playable responses, the most common being 1...d5 and 1...e5, which stake out a claim for central space. Another response, 1...b6, intends to fianchetto a bishop to pressure white's weakened pawns, and forestall a White kingside expansion with g4.

One of the weaker plausible responses by Black would be 1...f5, when White can play 2.d4, transposing to a sharp line against the Dutch Defense introduced by Korchnoi. White's idea is to play 3.g4!? as a pawn sacrifice (2.g4!? is also possible), one possible continuation being 2.d4 Nf6 3.g4!? fxg4 4.hxg4 Nxg4 5.Qd3 Nf6?? (5...g6! is forced) 6.Rxh7! Rxh7 7.Qg6#.

[edit] Popular Culture

The Clemenz Opening is featured in an informal game between Lisbeth Salander and her guardian in the 2011 film The Girl with the Dragon Tattoo. Lisbeth's reply to 1.h3 is the symmetric 1...a6.
