Commentary

  • "[5.Ng5 is] The Allgaier Gambit. If instead the Kt be played to K 5, we have the 'Kieseritzky'" (Marshall, p. 86).
  • "1st.—Allgaier's Mode, Kt. to Kt. 5 at 5th Move.
    2nd.—Kieseritzky's Mode, Kt. to K. 5 at 5th Move.
    This important opening in its two forms now to be examined, differs from the King's Knight's Ordinary Gambit, the Cunningham, the Salvio Cochrane, and the King's Bishop's Gambit, in this respect, that first player at No. 4 moves P. to K. R. 4 instead of B. to Q. B. 4 or Castles. The first form to which Allgaier gave much attention involves the sacrifice of a piece at White's 6th move ; although not theoretically or strictly sound, it yields an attack of a very brilliant kind, although of not so sound, lasting, or enduring a character as that afforded by Kt. to K. 5, the move with which Kieseritzky's name is identified. Both, however, are remarkably fine debuts, producing quite early in the game very critical positions, requiring great nicety of calculation and powers of combination : hence the opening has always been in great favour with the finest players. Anderssen, Steinitz, Zukertort, and Blackburne all evince great partiality for it, and during recent years Mr. Macdonnell has conducted the opening with remarkable skill and success" (Bird, pp. 80-81).
