Kibitzer's Corner
May-04-04  Poulsen: IM Jens Enevoldsen was the no. 1 player in Denmark before IGM Bent Larsen.

Famous game: J Enevoldsen vs Nimzowitsch, 1933

  Benzol: Jens Enevoldsen
Born 23rd September 1907 in Copenhagen
Died 23rd May 1980
Danish champion in 1940 (after playoff), 1943, 1947 (after playoff), 1948 and 1960.
Oct-26-07  sfm: Jens Enevoldsen was an excellent and brillant chess writer. His chess self-biography "30 years at the chess board" and "World's best chess", vol.1+2 (In danish, never translated) are outstanding works.

  Benzol: "Jens Enevoldsen died on May 23rd, 1980, aged 72.

Jens would probably be unknown to New Zealanders except Ortvin Sarapu and myself. My debt to Jens is almost the same as it is to Bill Reindler, for Jens gave 3 players the chance to lay the groundwork for their chess career - IGM Bent Larsen, IGM Walter Browne and myself. Each of us was able to live in his little attic flat in the middle of Copenhagen for a year, with no rent to pay and just chess to play. If the Danes deserve their reputation as "characters" then Jens helped get it for them. Cigar-smoking, brandy-drinking, music-loving and good-living were Jen's trademarks, along with his open-top Triumph Herald in a country of Volvo's, Volkswagens and Saabs. He earned his living with words, being Denmark's top writer on bridge and chess for many years. It is easy to dismiss lesser-known International Masters as being just that. Jen's achievements in chess were more than minor. He was an original endgame theorist, his work on R+P vs B being freely cribbed by Russians and others. He beat Tartakower in a match. He played in 10 Olympiads. His proudest chess exploit was beating Nimzowitsch with 6 consecutive knight sacrifices.....and all this was done as a dedicated chess amateur - he refused to take chess seriously in case he lost his love of it". - A personal appreciation by Ewen Green.

Jan-15-08  brankat: Only a few days ago I read somewhere on these pages that Mr.Jens Enevoldsen was buried right next to his old friend and teacher A.Nimzowitsch.

And yes, then I found the link and saw the photo of their grave-site.

Jan-15-08  TheBB: <His proudest chess exploit was beating Nimzowitsch with 6 consecutive knight sacrifices>

J Enevoldsen vs Nimzowitsch, 1933

I only count five knight offers. And they're not consecutive.

Jan-15-08  brankat: <TheBB> Aren't we ever fussy today :-)
Premium Chessgames Member
  Benzol: <Gypsy> I'm hoping you eventually post the solutions to those two problems. :)

<TheBB> Ewen's memory might be slightly at fault. Actually he wrote that in 1980. However, imagine what it was like to be with and playing chess with Jens Enevolsen, Bent Larsen and Walter Browne!

Jan-15-08  TheBB: <brankat> What?! I was promised <six consecutive> sacrifices. My chess heart was pounding wilder than ever before. But I was let down :(.
Premium Chessgames Member
  Gypsy: <Benzol: ... I'm hoping you eventually post the solutions to those two problems.> Yeah, I will get to it at some point. Presently, I am still exhausted from transcribing the Russian follow ups -- Baranov, 1954 and especially Majzelis, 1963 -- which can be found with yesterday's Live Game, Radjabov vs Van Wely, 2008.
Jan-15-08  brankat: <Gypsy> <I am still exhausted from transcribing the Russian follow ups -- Baranov, 1954 and especially Majzelis, 1963 ,,>

This kind of a work seems to be even more tiring than mountaineering :-)

Premium Chessgames Member
  Gypsy: It does <brankat>. I am just about to post the solution to the simpler of the Enevoldsen's studies, and I am about as tired as if I were leading over some full six pitches of rock. :-)

  Gypsy: <Enevoldsen, 1949.> White wins.

Before White can play Rxa7, Black king has to be pushed farther away: <1.Kc6 Bb6 2.Rd7+ Ke6> (If 2...Ke8 3.Kd6!, then either 3...Kf8 4.Ke6 Kg8 5.Rf7! and Rf1 and the White king decisively returns to the Pa7; or the bishop moves and White wins according to a process known from J. Berger, 1889 given bellow.) <3.Rb7! Be3> (3...Bf2 4.Rb2...; 3...Bd4 4.Rb4 Ke5 5.Rxe5!...) <3.Rb2!...> (The hits on the bishop gain time.) <3...Bg1 5.Re2+ Kf7 6.Kb7...> (Black king is now far enough. Still, all has to be meticulously set up.) <6...Kf8 7.Ka8! Kf7 8.Rg2!...> (Again, rook needs to reach 7-th rank with the help of a hit on the bishop.) <8...Bd4> (8...Bd4 9.Rd2... and 10.Rd7+) <9.Rg3!...> (The bishop now has to leave the files e,f, and g.) <9...Bd4 10.Rd3 Bg1 11.Rd7+ Ke8 12.Rxa7...> and wins.

Here is the auxiliary study by <J. Berger, 1889>. White wins (Black draws).

click for larger view

<1.Ke6!> (Threatens to simultaneously hit the bishop and create mating threats; e.g., 1...Be3 2.Rd3!...) <1...Kf8 2.Rf7+! Kg8> (2...Ke8 3.Rb7...) <3.Kf6 and 4.Kg6> with a win.

click for larger view

White plan is to force Black bishop to move so that it eventually can not run for a mat. <6.Rf1 Bh2 7.Rf2 Bg3> (A new motive appears after 7...Bd6 8.Rd2 Be7: 9.Ra2! Kf8 10.Ra8+...; if 7...Bg1, then 8.Rg2...) <8.Rg2...> and wins. If 8...Bf4, then 9.Kf5+... If 8...Bh4, then 9.Kh5+... And in all other cases the basic theme of concurrently hitting the bishop and threatening a back rank mate comes to play.

Btw, Black-to-play has a defense in the Berger position : 1...Kf8! 2.Ke6 Kg8! 3.Kf6... (If 3.Rf7 Bd4!, then White king can not get to g6.) 3...Kf8! =. For instance, 4.Rd6 Ba5! 5.Ra6 Bc3+. However, this defense does not apply to the Enevoldsen position because of the extra pawns.
