A few posts ago (see "London calling... Seven Months of Blog") I asked readers to suggest "another totally obscure and disreputable tactical opening line or gambit that I could go digging for information about, while I'm researching the Jerome Gambit."
Jerome Gambit Gemeinde member Pete Banks ("blackburne"), in a Comment, suggested 1.h4, a move with which he has had some success, following his own idea of 2. g3, 3.Nh3, 4.Bg2, and 5.0-0.
So I did a little research.
Althought Tim Harding, in his Dynamic White Openings (1989), calls 1.h4 "The most despised of openings, not even worthy of a name," it has sometimes been called the Deprès Opening, according the Oxford Companion to Chess (1984).
More often, though, 1.h4 goes by the name of the Kadas Opening. Eric Schiller, in his Unorthodox Chess Openings (1998, 2002), writes
He is referring to Hugh E. Myers, who in his Exploring the Chess Openings (1978) had this to sayThe Hungarian player Kadas has the dubious distinction of being perhaps the greatest living exponent of 1.h4, a move even Myers, a true fan of bizarre openings, considers poor.
If there were an election for the worst possible first move, 1.P-KR4 would have excellent winning chances.
Grandmaster Bent Larsen, in the Encyclopedia of Chess Openings, Volume A (1979), gave "1.h4? e5 =/+"
So Kadas' Opening would seem to meet the criteria set above for "disreputable" – even if it receives more complete and respectful treatment in Stefan Bücker's Groteske Schacheröffnungen (1990).
Do readers have other suggestions?
