In this game, the older defense 4...d5 is examined. This was followed up (after 5.g5) with 5...d4 or ...Bg4, but here a new continuation is played. This game may have been played for the purpose of examining the Swiss Gambit, and my not be a serious game.

Annotations, probably by Krejcik, condensed:

5...Ng4 <For 5...d4 and 5...Bc8 see the games 1645-1647 of the July-August 1912 'Wiener Schachzeitung', pp. 196-197. The text move is a magnificent novelty, which is unlikely to be correct.>

6.h3 <Best was 6.Be2 e5 7.Bxg4 exf4 8.Bxc8 Qxc8 9.Nxd5 Bd6 10.Qh5+ and wins or 6.Be2 h5 7.d4! (7.h3 e5 8.hxg4 exf4 9.gxh5 f3 10.Bf1 Qxg5) 7...e3! (7...c5 8.h3 cxd4 9.Qxd4 e6 10.hxg4 and wins) 8.Qd3 Nf2 9.Qg6+ Kd7 10.Nf3!

I) 10...Nc6 11.Bb5 Qe8 12.Bxc6+ bxc6 13.Ne5+ Kd8 14.Nxc6+ Kd7 15.Ne5+ Kd8 16.Nf7+ Kd7 17.Bxe3 Nxh1 18.Nxh8 and the ♘h8 is easily rescued while the ♘h1 is lost, so White wins. 12.Ne5+ Kd8 13.Nf7+ Kd7 14.Na4 Ne4 15.Qxe4 Qxf7 (15...dxe4 16.Nc5#) 16.Nc5+ Kd8 17.Qxe3 is redundantly artificial. 11...e6 12.Bxc6+! Kxc6 (or else loses the ♕ after Ne5+) 13.Ne5+ Kb6 14.Bxe3 Nxh1 15.Nf7 followed by Nxh8 and wins. If 11...Ng4 12.h3 and wins.

II) 10...Qe8 11.Ne5+ Kd8 12.Nf7+ Kd7 13.Bxe3 Nxh1 14.Nxh8 and wins.

III) 10...Ng4 11.h3 and wins.

IV) 10...e6 11.Ne5+ Ke7 12.Nf7 Qe8 13.Nxh8 Nxh1 14.Bxe3 and wins.

V) 10...c6 11.Rf1 Ng4 12.h3 Nf2 13.Bxe3 Nxh3 14.Rh1 Kc7 15.f5 etc..> This annotation is a bit corrupted by the wrong move numbers. After 10.Nf3 is a diagram and the variations begin, the first with <I. Sb8-c6 10.Le2-b5 Dd8-e8> etc., when it's actually 10...Nc6, so 11.Bb5 Qe8 etc.. I corrected this mistake, but it affected the other lines as well, as for example the "redundantly artificial" (a try to translate <überflüssige Künstelei>, <überflüssig> = redundant, <Künstelei> is something artificial) begins <11.Sf3-e5+ Kd7-d8> which makes no sense as the Black ♔ can't access d8 prior to 11...Qe8. So I figured that this lines was a deviation from 12.Bxc6+ (and the 12.Ne5+ appears to be at least as strong as the recommended 12.Bxc6, e. g. 14.Nxd5 instead of 14.Na4).

6...e5 <The move Ng4 becomes understandable, Black gets strong ♙ play.>

8.Nh3 <8.g6 Qg5! 9.gxh7 Bxg4 10.Be2 f3 and wins.>

10.d3 <10.Nxd5 loses on the spot but 10.d4 was necessary. Of course, there would have been dangers also, e. g. 10.d4 O-O 11.Ncxd5 Bh4+ 12.Kd2 Rxf4 13.Nxf4 (13.Rxh4 Qxd5!) 13...Qxd4+! 14.Nd3 e3+ 15.Ke2 Bxg4#. The text move allows a magnificent combination.>

11...e3+ <!>

13.Kd2 <After Kf3, Black would likely win back the gambit piece first. Interesting would also be immediately 13...Bxg4+ 14.Kxg4 Qg5+ 15.Kf3 Qg3+ 16.Ke4 etc..>

15.Qf3 <Equal on material, Black has a terrifying attack. White should be lost in all variations.>

15...Rxf4 <!>

<A dignified miniature! (Eine gediegene Miniatur!)>
