|Mar-30-04|| ||Eatmysacs: Jaenisch is a fascinating player. His risky behavior over the board spawned some very interesting gambits today, including the Jaenisch Gambit, 1. c4 b5. Also the Schliemann-Jaenisch Gambit, 1. e4 e5 2.Nf3 Nc6 3.Bb5 f5 4.Nc3 fxe4 5.Nxe4 d5 6.Ne5 dxe4 7.Nxc6. |
|May-25-04|| ||tacticsjokerxxx: True.. 1.c4-b5! is an underrated response to 1.c4, 1.c4 works so well because people haven't figured out that -b4 is the correct response yet. |
|May-25-04|| ||AgentRgent: I looked at 1.c4 b5 quite a bit as a possible response to the English. I play the Benko against 1.d4 and thought play would be similar (Actual transposition is possible, but unlikely). I found that even though black has similar play on the queenside, the lack of the pawn on d5 was actually a benefit to white. |
|May-25-04|| ||Lawrence: <tacticsjokerxxx>, "people haven't figured out that -b4 is the correct response yet." That's not surprising. |
|Oct-02-04|| ||Knight13: He had a bad Loss against NN since 1842. But his attacking strategy is well played. |
|Oct-02-04|| ||fgh: 1 c4 b5 doesn't seem very usefull to me. |
|Oct-03-04|| ||Kean: First time I hear about the 1.c4 b5 gambit, I guess the idea could be a bishop on b7 , pawn on d5 and the rapid sizing of e4. |
|Dec-11-04|| ||DanielBryant: Anybody here ever used it? |
|Nov-05-05|| ||royspeck: I played the Jaenisch variation of the Evans gambit against an advanced player. I won the game with a powerful attack. I would suggest an example of this variation should be put in Jaenisch games.|
|Aug-11-06|| ||BIDMONFA: Carl Friedrich Von Jaenisch|
|Sep-15-06|| ||FHBradley: The biographical data on Jaenisch is (are?) slightly misleading. Technically speaking, if I may put it this way, he was Russian, but in fact he was (and always regarded himself as) a Finn. Anyone with knowledge of the Finnish language can easily figure out the linguistic origin of his surname.|
|Sep-15-06|| ||moppa: Oh, he was a Finn? (Finland wasn't actually an independent country back then) I didn't recognize that from the name - but now when I know it, it's propably written Jänis (a with dots is often replaced with ae)in Finnish. Jänis is a rabbit in english. However, Carl Friedrich isn't very Finnish name, altough there were quite a few Swedish-sound names in the 1800's|
|Oct-25-07|| ||melianis: Vyborg was quite a mix of nationalities back then, finns, karelians, swedes russians, germans, estonians, tatars, others. Nice to know that he regarded himself a finn.|
|Feb-12-08|| ||brankat: C.F.Jaenisch's work on openings, together with that of P.R.von Bilguer's ("Handbuch") is regarded as the birth of modern openings' theory.|
|Feb-12-08|| ||sigi: <brankat>
During the preparation of both books their authors were in close contact. In 1842 Jaenisch visited twice Berlin and analysed openings with von der Lasa:
"Der Austausch meiner Ideen mit dem russischen Gaste geschah weniger contradictorisch in der gespielten Partie, als gemeinsam auf dem theoretischen Gebiete der Eröffnungen. Ich darf wohl behaupten, dass unsere, unter zwei Verfassern gewiss seltene Vereinigung der Forschung, welche durch fortgesetzte Correspondenz seitdem unterhalten worden ist, zu sehr günstigen Resultaten für die Vervollkommnung des Bilguer'schen Werkes und für die Analyse nouvelle, deren erster Band 1842 in Dresden gedruckt wurde, geführt hat."

|Feb-12-08|| ||brankat: <sigi> Thank You so much for this information. I've been wondering about it myself. |
All 3 were of approximately the same generation, and involved in very similar kind of work, it would have seem natural for them to be in contact.
It was quite fortunate that Mr.v.d.Lasa was not only a very talented master, but also a capable analyst, a far-sighted person. And above a loyal friend to P.R.Bilguer.
We all owe a debt of gratitude to these Pioneers of Chess theories.
|Aug-11-09|| ||WhiteRook48: Happy birthday!|
|Sep-15-10|| ||FHBradley: Happy Birthday Mr. Jänisch! Serving in the Russian army as an engineer-officer, he could retire at the ripe age of thirty, after which he dedicated the rest of his life to chess and mathematics. A nice career.|
|Apr-11-11|| ||Penguincw: Happy Birthday Carl Friedrich Von Jaenisch!|
|Apr-11-12|| ||brankat: Happy Birthday!|
|Oct-22-13|| ||Karpova: The 'British Chess Magazine' Almanac, p. 1, March 1882 claims he died March 17, 1872 and Gaige (p. 191) agrees.|
