Discussion

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 White's kingside, 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 first move, it is among the rarest of the 20 possible first moves. Nevertheless, IM 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 that has been dubbed the "Creepy Crawly". The “Creepy Crawly” is also known as the Global Opening.

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 (or even 1...b5), intends to fianchetto a bishop to pressure White's weakened pawns, and forestall a White kingside expansion with g2–g4.

1...f5 is probably not Black's best reply to 1.h3, since White can then play 2.d4, transposing to a sharp line against the Dutch Defense once tried by Viktor Korchnoi.

gollark: No.
gollark: Because, as I said, copypasting HTML in each page instead of doing it centrally makes making changes horrible.
