V 1451 K3 opy 1 v^be 1Rice (3ambit SUPPLEMENT TO FOURTH EDITION COMPILED AND EDITED BY DR. H. KEIDANZ MAY, 1909 PUBLISHED BY THE AMERICAN CHESS BULLETIN J50 NASSAU STREET, NEW YORK CITY PRICE (INCLUDINa POSTAGE): 17 CENTS ADDENDA. After going to press, Mr. Rice found a much better continuation for White in place of variations 9, 10, II, 12, 13 and 14 by means of a sacrifice of the Queen's pawn. After Black's move of K — Q, White should answer P — Kt3. Against this Black seems to have two main lines of play, viz, R — K or Q — B4 ch. If i R — K ; 2. P— Q6, QxP (If PxP, B— R3, etc.) ; 3- Kt— K4, Q— Kt3 ch; 4. K— R2, KtxB ; 5. PxKt, B— B4 (H P— KB4; 6. Q— Q3 ch, B— Q2; 7. R— Q, R— K2; 8. B— R3, etc.); 6. Q— Q3 ch, K— B ; 7. Kt— Q6 ch, PxKt ; 8. RxR ch, K— B2 ; 9. R— K7 ch, etc. If, however, Black plays P — B6 at once, in reply to P — QKt3, then the following ■ variation would arise: i. Q— K3, R— K ; 2. P— Q6, PxP (If QxP Kt— K4, Q— Kt3; Kt— B5, etc.) ; 3- B— R3, P— KB4 4. QR-Q, QxP (If ....P-KB5; Q-Q4, etc.) 5. BxP, etc. ERRATA. Preface : Read fifteenth line: 12.

Black's 'eleventh move of Kt — O2, in the Jasnogrodsky Variation of the Rice Gambit, appeared in the first edition of that gambit edited by Lipschuetz, and it was replied to by 12 PxB and upon Kt taking" Pawn the analysis con- tinued 13 P — QKt3, and as the reply to this was weak, a win for White was demonstrated. In the London Rice Gambit tournament of 1904, however, Mr. Napier showed that the continuation published in the Lipschuetz edition was defeated by an elegant sacrifice of the Knight. This caused a panic among the White forces so that the tournament, which up to that time had been altogether favorable to White, finally ended in a victory for Black. Nevertheless, I did not feel that the unsoundness of the gambit had been actually demonstrated, inasmuch as many lines were still open to White, and I therefore persistently continued the inves- tigations, particularly along lines arising out of 12 B — Kt5, K — Q;,i3 BxKt, BxB; 14 RxB, QxP; 15 RxKt, etc. I did not, however, confine myself to that line, but also gave consideration to the line of 12 PxB, PxKt; 13 Q — K2, P — KB3 ; 14 Kt — O2, R — Q ; but, owing to incorrect after-play, came to the conclusion that this line led to defeat. Last summer Mr. Janowski, however, made a quite independent search in the same direction and came to the opposite conclusion, which he published in Le Monde Illustre. In this analysis he paid no consideration to 14 . . . R — O, but found against the moves of 14 . . . B — Q2,or B — B4 White would main- tain equality, if not gain superiority, by 15 Q — B2. This indication, although il- luminating, was nevertheless so brief that it could only act as guide into the outworks of the positions. Mr. Janowski also gave some consideration to the move 12 . . . QxP, regarding which he gave several variations in an earlier number of Le Monde Illustre which, while correct in themselves, in no manner exhausted the possi- bilities of Black, and, therefore, could not be considered as actual demonstra- tions of the soundness of the gambit, inasmuch as it frequently happened in the course of the analysis that a line of play that demonstrated wins for White in numerous variations had nevertheless to be abandoned finally on account of defeat in a variation subsequently coming to light. However, the suggestions of Mr. Janowski were so promising that I determined to subject them to a most exhaustive examination. To that end, I availed myself of the most valuable assistance of a number of the strongest players of the Rice Chess Club, who volunteered to conduct the black pieces while I played the white, so as to make as certain as possible in the analysis that every resource of Black should, as far as possible, be discovered. As the result of this analysis, I now present, through the American Chess Bvdletin, fifty-five variations, together with numerous sub-variations, which have been critically examined and compiled by Dr. H. Keidanz, the editor of the fourth edition of the Rice Gambit, as a substitute for variations yy to 108 of that edition. Should the analysis prove correct, and thus the soundness of the Rice Gambit established, I and my colleagues in this work will feel ourselves com- pletely repaid for our labor by the broadening of the scope of the openings avail- able for matches and tournaments now unfortunately so restricted, as in that case the King's Gambit could be offered with no less safety than the Queen's Gambit, and other close openings, which now monopolize important chess events.

Q — Q4, etc. There are only two main lines of play at the dis- posal of Black, KtxP, as analyzed in vari- ations 7-14, and QxRP, analyzed in the re- maining variations. (b) Forced, and now Black cannot at- tack the King's Rook's Pawn for some time to come. (c) Credit is due to D. Janowski for having seen the far-reaching consequences of this move in conjunction with the sub- sequent Queen's move. An analysis of this line of play was recently published by Janowski in he Monde Illiistre. (d) If 15 P — Kt3, in order to pre- pare for castling, White replies, 16. P — QKt3, castles QR ; 17.
