|Sep-20-04|| ||Honza Cervenka: 42...g5 was a blunder, but the game was already lost. |
|Nov-20-04|| ||ForeverYoung: This was a curious contest involving symmetry. "Lesser-Known Chess Masterpieces: 1906-1915" gives white the edge after 26 Nc5 and labels 27 ... Ng5 a mistake. It points out after 32 ... Be6 33 g3 Bb8 34 f4 followed by Ne3 wins the pawn on d5. |
|Dec-02-08|| ||Pawn and Two: This tournament attempted an unusual time limit experiment. In "Carl Schlechter! - Life and Times of the Austrian Chess Wizard", this rule was stated as: <...no limit for the first six hours of play; after that players had to make 15 moves an hour. Contestants who exceeded the time limit were assessed a penalty of one German mark per minute.>|
The above book stated that Tarrasch was the most celebrated victim of this rule, in his second-round game with Salwe, he not only suffered defeat, but he had to pay the equivalent of "four pounds and 15 shillings" for exceeding the time requirement!
In 1906 U.S. dollars, this fine would have been approximately $4.86 (1 pound) x 4.75 = $23.09. At that time the German mark was worth approximately 23.79 cents. Therefore, Dr. Tarrasch exceeded the time limit in his game with Salwe by approximately 97 minutes!
The book "Carl Schlechter - Life and Times of the Austrian Chess Wizard", stated that some competitors avoided these fines by agreeing to make meaningless moves. "The Year Book of Chess" reported that because of these agreements, the rules were then changed so no time limit was observed, except for adjourned games.
|Dec-31-08|| ||whiteshark: <Pawn and Two> Thanks for explaining the <unusual time limit>. According to http://www.schachbund.de/chronik/me... Tarrasch 'invested' 60 Marks only.|
|Aug-08-09|| ||Pawn and Two: The opening in this game was interesting in that the position had perfect symmetry after 11...Rad8. Even at move 18, the position was very symmetrical.|

Fritz indicates this position is equal, and that White could maintain an equal position by: 18.Qd2 Bd6 19.Bb2, or 18.Qc1 Qd6 19.Nb5, or 18.g3 Qd6 19.Nb5, or 18.a3 Qd6 19.g3, or 18.h3 Kg8 19.Qd2, or 18.Qc2 Qd6 19.Qd2.
Instead, Salwe erred with: (-.65) (20 ply) 18.Ne2? Ne4. After the game continuation: 19.Ng3 f5 20.Bd3, Fritz indicates Black's best choices were: 20...Bd6 21.Qb1 Rc8, or 20...Rc8 21.a3 a5, or 20...Re6 21.a3 a5, or 20...Bf4 21.Bb5 Rc8, with some advantage for Black in each of these continuations.
The last variation, 20...Bf4 21.Bb5 Rc8, could have led to an interesting ending where White has the exchange, but Black has the bishop pair and a pawn advantage: 22.Ne5 Nxe5 23.Bxe8 Ng4 24.Bd7 Ngxf2 25.Bxc8 Nxd1 26.Qb1, and then: (-.71) (21 ply) 26...Bxc8 27.Qxd1 Nxg3 28.hxg3 Bxg3.
Tarrasch's choice: (-.56) (22 ply) 20...a6 21.a3, also favored Black. Fritz indicates the best continuation was 21...a5 22.Qa2 Re7, with some advantage for Black.
Instead, Tarrasch played 22...b5 23.Nd2, with only a minimal edge for Black. Fritz indicates the best continuations are: 23...Ne7 24.Nb3 Ng6, or 23...Re7 24.Nb3 Qf6, or 23...Bc8 24.Nb3 Ne7, or 23...Qf6 24.Nb3 Re7, with almost equal positions.
After Tarrasch's 23...Nb8: (.04) (20 ply) 23...Nb8 24.Ngf1 Bf4 25.Nb3, the position was equal.
|Aug-08-09|| ||Pawn and Two: At move 25, Tarrasch should have continued by: (.08) (22 ply) 25...Nc6 26.Nc5 Bc8 27.Qa2 Qf6 28.f3 Nxc5 29.bxc5 Be6, with an approximately equal position.|
Instead, he made a small error by playing 25...Nd7?. White could then have gained a small edge by playing 26.f3!. <ForeverYoung> has noted that, "Lesser-Known Chess Masterpieces: 1906-1915", stated that White had the better game with 26.Nc5.
Fritz indicates the correct way to get the edge after 25...Nd7?, was by: (.33) (22 ply) 26.f3! Nd6 27.Nc5 Qf7 28.Nxb7 Nxb7.
After 26.Nc5, Black could have maintained a near equal game with: (.18) (22 ply) 26.Nc5 Ndxc5! 27.bxc5 Bc6.
Instead of playing the correct 26...Ndxc5!, Tarrasch erred and his position was at a clear disadvantage: (.78) (21 ply) 26...Bc8? 27.f3.
After 26...Bc8? 27.f3, Fritz indicates Black's best chance was: (.70) (22 ply) 27...Nexc5 28.bxc5 Qf7 29.Qf2 Nf6, and Black still has chances of holding this position. One continuation could be: (.70) (20 ply) 30.Bc3 Bc7 31.Ng3 Nh5 32.Nxh5 Qxh5.
Instead of playing 27...Nexc5, Tarrasch played 27...Ng5. "Lesser-Known Chess Masterpieces 1906-1915" assigned a (?) mark to 27...Ng5, but did not provide any analysis or alternative moves.
Fritz indicated the following analysis: (.87) (22 ply) 27...Ng5 28.h4 Nxc5 29.dxc5 Nf7 30.Rxe8 Rxe8.
As I have noted, 27...Nexc5 would have given Black drawing chances. However, even after 27...Ng5, White has to play very carefully to maintain his advantage. The game continuation followed Fritz's analysis through 30.Rxe8 Rxe8.
At move 31, White could try win a pawn after 31.Bc2 Be5 32.Qc1 Qe7 33.Bxe5 Nxe5 34.Rxd5 Bb7 35.Rd4 Nc6 36.Rf4 g6 37.Qb2+ Qg7 38.Qxg7+, but after 38...Kxg7 39.Kf2 Rd8!, Black has good drawing chances.
Best for White, after 30.Rxe8 Rxe8 was probably: (.78) (22 ply) 31.Qc2 Nd8 32.a4, (.72) (20 ply) 32...Bd7 33.axb5 axb5 34.Qf2 Qf7 35.Re1, and White has good winning chances as Black's b-pawn and d-pawn are very vulnerable.
|Jun-13-16|| ||offramp: AFAIR there was no time limit in the 1894 Tarrasch-Walbrodt match, for example Tarrasch vs K A Walbrodt, 1894, which Tarrasch won 5-0 with one draw.|
I wonder what was the last major chess event without a time limit?
There could be one nowadays, because modern players would not spend long times on moves; they are not used to it. Of course, there is no need for such an event.
