  morfishine: <Newzild> & <Sokrates> Thats where I had problems visualizing a decisive position:

(1) <19.Rxh7> Bxd4 20.Qxg6+ Rg7 and for some reason, I couldn't see the simple winning continuation 21.Qe6+ Kf8 22.Rh8+

About all I could conclude was "Although unable to see the winning continuation, In the absence of any other idea, 19.Rxh7 is more than likely the first move..."

  David2009: M Katetov vs Golombek, 1946 puzzle position;


click for larger view

As <Morf>, <sokrates> and <newzild> point out, it is challenging to visualise the complete combination including the 19...Bxd4 defence from here. Even in the main line, one has to visualise that after 19.Rxh7 Kxh7 20.Qxg6+ Kg8 21.Rh1, mate is indeed forced.

Golombek in the book of the tournament points out that 11...a6? was far too slow and that 11...Qa5! held the balance as in Boleslavsky vs C Kottnauer, 1946. Golombek also criticises 18...Ne8? commenting "Better is 18...Kf8 when White has to proceed more slowly with f4 and f5 though of course the position is still won for him".

<offramp>: OTT comment. Golombek finished one point ahead of Katetov in the tournament, winning five games (against the bottom five finishers), drawing three and losing five.

  gofer: Black has two mild threats; Qxc2+ and Bxd4 niether are much to write home about, but white does need to keep them in mind, when planning an attack, (i.e. giving up Bc3 lightly isn't going to be best way to avoid Qxc2#)

<19 Rxh7 ...>

The rook sacrifice is thematic. The king is the sole defender of Ph7 and that means that black can be forced into difficult decision;

19 ... Bxd4
20 Qxg6+ ...

20 ... Kf8
21 Qxf7#/Rxf7#

20 ... Ng7/Bg7
21 Rh8+ Kxh8
22 Qh7#

20 ... Rg7
21 Qe6+ Kf8
22 Rh8+ Rg8
23 Rxg8#

<So Bd4 is safe!>

19 ... Kxh7
20 Qxg6+ Kg8
21 Rh1! ...

The threat of 22 Rh8+ Kxh8 23 Qh7# has to be met!

21 ... Nf6 (Kf8 Bxg7+ mating)
22 Bxf6 Kf8 (Rxf8 23 Rh8+ Kxh8 Qh7#)
23 Bxg7+ Ke8
24 Rh8+ mating

<So Rh7 is safe!!!!>

<19 ... Nf6>
<20 Bxf6 exf6>
<21 Qxg6 ...>

21 ... f5
22 Rdh1 Kf8
23 Rxg7 Rxg7
24 Rh8+ mating

<21 ... Kf8>
<22 Rdh1 Ke7>
<23 Rxg7 Rcf8>
<24 R1h7 Ke8>
<25 Rxf7 Rxf7>
<26 Qg8+ Rf8>
<27 Qe6+ Kd8>
<28 Rxc7 Qxc7>
<29 Qe7+> mating soon

~~~

Yep!

Just ask Gordon Welchman, Stuart Milner-Barry or Alan Turing about that-if you ever catch up to their ghosts!

May-15-14  Vdh: 19. ...Rf6 will give some time for black to bring the queen into play after 20. Bxf6 exf6 but it is not clear if the material lost can be recovered.
May-15-14  satkul: a very nice combination

  kevin86: I saw this one coming: the finish is the same as the Marshall- Burn pipe game:

22 ♖h8+ ♔xh8 23 ♕xh7#

May-15-14  Chess Dad: I've spent about 15 minutes, and I can't find a way to make either Rxh7 or Bxg7 to go anywhere.

It's tempting, since I have Rd1 available to swing over and control the h file, and Bd3 controls g6 if I can just get rid of h7.

I'll play Rxh7 and if that's the game move, I'll see Black's response and go from there.

............

Ok, so it's Kxh7. Is the problem easier now?

20. Qxg6+ Kg8 21. Qh7+ Kf8

I think those are the next two moves. Are they?

Nope. That's the move I missed. Rh1 before Qh7+ That's why I couldn't get the follow-up to work.

But looking at the board now, I can't understand why black played Rf6. That's mate in two. Kf8 also loses in two moves. But what about Nf6? Doesn't that help?

May-15-14  LIFE Master AJ: 19.Rh7 was my try ... after just a few minutes.
May-15-14  sombreronegro: I could see all forcing moves

Rh7 Kh7 20. Qg6 Kg8 21. Rh1 Rf6 with 2 pawns for a rook with a powerful attack but I can say I saw a concrete line until that point. Now its easy to see the lethal light square weakness with the knight retreat on e8. The king was left as the main defender of g6, f7, and h7, not so fun with the white square bishop aiming into the area. OTB I probably would have just tried to double rooks on the h file.

May-15-14  sombreronegro: Thing is taking the time might mean loosing the pin on the black bishop. That would not be a desirable simplification. Keeping the black square bishops on the board was essential to creating too much traffic for the rook to cover h7.
May-15-14  BOSTER: I want to give thsi pos. to show the tactical motif interference.

The square g7 can be protected
by bishop, by knight, and by rook.
The most interesting Rg7.

In our visualising picture the bishop d5
was still protecting h8 square,
but line d5-h8
was interrapted.

This is why many players did not see Qe6+ Kf8 Rh8+.

May-15-14  Patriot: White has the bishop pair. Black threatens 19...Bxd4.

19.Rxh7

19...Kxh7 20.Qxg6+ Kg8 21.Rh1 Kf8 22.Bxg7+ Rxg7 23.Rh8+

19...Kxh7 20.Qxg6+ Kg8 21.Rh1 Kf8 22.Bxg7+ Nxg7 23.Rh8#

19...Bxd4 20.Rxf7 Kxf7 21.Bxg6+

May-15-14  Rookiepawn: Hum...

19... Bxd4
20. Rxf7 Bxb2+

This os the only desperate move that would come to my mind, if W gets too greedy, I think...

21. Kxb2 Qc3+ followed by Kxf7 might hold?

Of course W can simply go 21. Kb1! Not letting the BQ get hold of the long diagonal.

May-15-14  Rookiepawn: There was a time in which I tried to understand chrisowen's posts. I thought something was wrong either with my English, my chess... or both.

  john barleycorn: <Rookiepawn> there was a time they were easier to understand. Don't know what changed his style. But by the chessical content they are good.

Premium Chessgames Member chrisowen: Hey pal is time it or did he just get outplayed? Is that a viable state black can hold? White is railing against Ng5+, the rushing in of the knight is too hasty, h6 gets the beers he bargained for. Dxe4 Bxe4+ Kg8 Qd3 is like mountain dew refreshing the attack. Whilst black does plod onwards 14.g4 is gold dust. Wrestling an angel like Gofshtein requires patience yet Tseitlin's pieces are a rabble ringed in the queenside. White rampages like a lion in zion, you tell a vivid picture via 10.h4 of spring.>

  patzer2: Black's first significant mistake was 12...b5?! After 12...b5?! 13. Nd5! (+1.85 @ 20/47 depth per Fritz 12) White has all the winning chances.

More prudent was 12...Qa5 with counter play.

The final blunder was 12...Ne8?? After 12...Ne8?? 13. Rxh7 Black's busted.
