Mar-06-06  Resignation Trap: <LIFE Master AJ> If you want to know how the name of this city is spelled, try this: http://www.buesum-information.de

If you go to the page with the alternate game score, it reads :"Busum (Netherlands)", however the city is in <Germany>!

This tournament was another feather in the cap for Bent Larsen , who finished first, ahead of the Soviet representatives Lev Polugaevsky and Alexander Zaitsev , who had tied for first in the USSR Championship a few months earlier.

See how Larsen stomped a fellow GM in only 15 moves: Bobotsov vs Larsen, 1969 .

The other notable factoid about this tournament was the performance of the veteran player Friedrich Samisch , who went 0-15, by losing all his games on time!

Mar-07-06  LIFE Master AJ: <RT> Thanks for the info, I am sure that most of the members here did not know many of the cool little factoids that you shared with us.
Mar-07-06  EmperorAtahualpa: <Resignation Trap> It is actually very likely that this game was played in the Dutch city of Bussum.
Mar-07-06  Resignation Trap: <EmperorAtahualpa> I took that possibility into consideration. However, I also looked at the crosstable of this event: http://xoomer.virgilio.it/cserica/s... , and I noticed many German players, but no Dutch players, so it seemed highly unlikely.

  whiteshark: Polugayevsky mentionend that "Black misses the interesting possibility of <17...Na5!>,

after which 18. Ne7+ can be quietly met by 18...Kh8, while the sacrifice of a piece for three pawns -18.Bxb6 axb6 19.Qxb6 (19.Qg3 Bxd5) 19...Bxe5 is in his favour."

May-25-14  hedgeh0g: What a cheeky finish: Black is given a taste of his own medicine with a sexy counterdecoy.

May-05-19  Walter Glattke: Very nice mate picture: 32.-Kf8 33.Bg7+ Ke8 34.Bf7# 27.-fxe5 28.Bxd8 Rxd8 29.Qc6 Nd6 30.Qd5+ Kf8 31.Qxe5 should win.
May-05-19  Steve.Patzer: Very sneaky with the Queen pinned.

  al wazir: I see that I commented on this game previously. On the first page I asked what happens after 27...fxe5.

But that was 12 years ago. Having forgotten that, this time I found 27. Bxf6 Bxf6 28. Rxe8+ Rxe8 29. Bxb7, winning a ♙. (If 29...Re5, then 30. Bd5+.)

May-05-19  groog: yes, really really sneaky, nice one Lev

27.B:f6 B:f6 28.R:e8+ R:e8 29.B:b7 Kf8
30.Bc6 picking up a pawn.

May-05-19  clement41: What a gem!
Twice the same tactical theme in the same combination (I am referring to the deflection of the enemy rook protecting its queen : 30...Re1+ and 32 Bd5+ ) Thanks Bilek for allowing a much prettier win than after the more prosaic 29...Qxc7
May-05-19  mel gibson: I wasn't sure,
The computer plays harder as Black.

May-05-19  schachfuchs: I calculated the line 27.Rxe5 Rxe5 28.Qc4+ Kg7 29.Qc7+ and Bxf6, at which I completely omit the counter 30...Re1+ 31.Kh2 Rxc1 !

btw: 27...fxe5 28.Bd5+ Kg7 29.Bxb7 Rd6 (what/where else? 29...Qxb7 30.Bxd8 Rxd8 31.Qxe5+ Kg8 32.Rc7 is hopeless) 30.Bc8 +-

  agb2002: White has the bishop pair for a bishop and a knight.

Black threatens fxg5 although White has Bxb7.

White has Bxf6 and Rxe5.

In the case of 27.Bxf6 Bxf6 28.Rxe8+ Rxe8 29.Bxb7 White wins a pawn (29... Qxb7 30.Qxe8+) but the presence of opposite color bishops may give Black drawing chances.

In the case of 27.Rxe5:

A) 27... Qxe5 28.Qxe5

A.1) 28... Rxe5 29.Bxf6

A.1.a) 29... Rf5 30.Bxd8 (30.Bxb7 Rxf6 - +) 30... Nxd8 31.Rc8 Rf8 32.Bd5+ Kh8 (32... Kg7 33.Rc7+ and 34.Rxa7 + - B+2P vs n]) 33.

A.1.b) 29... Re6 30.Bxd8 Nxd8 31.Bd5 wins decisive material.

A.1.c) 29... Ree8 30.Bxb7 + - [2B+P vs r].

A.2) 28... fxe5 29.Bxb7 + - [2B+P vs r].

B) 27... fxe5 28.Qc4+

B.1) 28... Kh8 29.Bf6#.

B.2) 28... Kf8 29.Bh6+ Ke7 30.Qc7+

B.2.a) 30... Qxc7 31.Rxc7+ Rd7 32.Rxd7+ Kxd7 33.Bxb7 + - [2B vs r].

B.2.b) 30... Rd7 31.Bg5+ wins a piece (31... Ke6 32.Bg4+).

B.3) 28... Kg7 29.Qc7+ wins the knight + - [2B vs r].

C) 27... Rxe5 28.Qc4+

C.1) 28... Kh8 29.Bxf6#.

C.2) 28... Kf8 29.Bh6+

C.2.a) 29... Ke8 30.Qg8+ Kd7 (30... Ke7 31.Qg7+ wins the knight as above) 31.Qf7+ Re7 32.Bc6+ Kd6 33.Qd5+ Kc7 34.Bxb7#.

C.2.b) 29... Ke7 30.Qc7+ as in B.3 (30... Rd7 31.Qxb8).

C.3) 28... Kg7 29.Qc7+ as in B.3.

May-05-19  Walter Glattke: Al Wazir: 27.Bxf6 Nd6 28.Rxe5 Nxb5 29.Rxb5 Rd2 30.Bd5+ Kf8 black wins. Nd5 is the key.

May-05-19  Jambow: Honestly although the full continuation alluded me, I think openening lines of attack with 27.Rxe5 considering 26.Bg5 preceeded it is somewhat natural as a potential move. This is further enticed if one also notices the bishop pair get lines of attack against the black king combined with the fact that the queen has c4+ to work with. Now arriving at 27.Qc7+ is where I might have lost the thread over the board since it is so hard to give up your queen in the midsts of an attack for me anyway. That aside seeing as it gives the rook control of the seventh and the light squared bishop has access to the D file maybe a glimmer exists to find the needle in the proverbial haystack. This since resulting position becomes within my limited depth of calculation.

Great position to get the creative juices flowing and enticing an insructive attacking combination to follow. In short worthy puzzle cg.com

  al wazir: <Walter Glattke: 27.Bxf6 Nd6> 28. Qd5+ Nf7 (28...Kf8 29. Rxe5) 29. Bxd8.

Am I overlooking something?

May-05-19  Pedro Fernandez: The only move I didn't see was 29...Kg8 (I thought 28...Qxb7, but it is plainly inferior), but after of it the subsequent moves were easy.

  TheTamale: Oh, thank God. I didn't notice this wasn't the Monday puzzle yet and despaired when I couldn't figure it out. Wasn't quite ready to hand in my hard-earned 1200 rating just yet.
