Kibitzer's Corner

Jan-16-09  Skoolboye: 67. Qc5 killed white.
Jan-16-09  zooter: hmmm...the site refreshed and all my comments went woof...

anyways, what's the idea behind 69...Qd7?

Jan-16-09  zooter: and just for people who are wondering what is going on, the initial position had 69. White to play wrongly
Jan-16-09  mig55: Rh1 Mate, so I see...
Jan-16-09  Peter Nemenyi: <zooter: and just for people who are wondering what is going on, the initial position had 69. White to play wrongly>

And then there was a moment when they'd changed it to Black to play, but still showed the position after Black's 68th, so Black had mate in one with Rh1. Easiest Friday puzzle ever!

Jan-16-09  MostlyAverageJoe: <zooter: what's the idea behind 69...Qd7?>

Threatens a forced mate via Rh1+ KxR Qh3+ Kg1 Qxg2#

Jan-16-09  dzechiel: White to move (69?). White is up an exchange. "Difficult."

Heads up! Black is threatening both 69...Rh1#, so our moves, whatever they may be, must be forcing or defensive in nature.

As far as I can see, there are seven moves that stop the immediate checkmate:

- 69 Rh8+
- 69 Qf8+
- 69 Rf3
- 69 Rg2
- 69 Kh3
- 69 Qc1
- 69 Rf1

Most of these moves just look bad to me. For instance after 69 Kh3 Qd7+ 70 g4 (70 Kh2 Rh1#, other moves lost material with check) 70...Qd3+ and the end is near.

And the "spite check" style moves (69 Qf8+ and 69 Rh8+) or kamakazi moves (69 Qc1 and 69 Rf1) just seem to throw away material.

Even 69 Rf3 allows 69...Qxc5 70 Rxc5 Bxf3 and black is assured at least a draw. It seems the move must be

69 Rg2

But this move is defensive and allows black at least a simple draw by 69...Qxc5 70 Rxc5 Bxg2 71 Kxg2.

There's something fishy going on here. As white is up in material, it may be that this position is actually black to move.

Time to check and see what's happening.

Jan-16-09  dzechiel: OK, now the position is after 69 Rg2 and it's labeled "Black to play." <sigh>
Jan-16-09  Ladolcevita: ==
its just a procedural error.

  chessgames.com: The position appeared incorrect on the homepage for about 15 minutes. Please do not use the kibitzing to make comments that would only make sense to people who experienced the error and its subsequent correction--that only serves to confuse the majority of people who see this puzzle later in the day. Just stick to the position at hand. Thanks.

  cu8sfan: Difficult indeed. Even after seeing the solution it took me a couple of minutes to understand the solution.
Jan-16-09  RandomVisitor: White had an advantage through most of this game, blowing it at 67.Qc5? (Qf3 or Re2 might be better) when 68.Kh3 would be equal.
Jan-16-09  EXIDE: Having problem finding the end move. What is blacks reply to white 71. Rg1.
Jan-16-09  zenpharaohs: I got Qd7, but didn't expect the response 70 Qf2. So I can't say I solved it.

I spent a while beating up all the other responses though....

Jan-16-09  DeepFriedLiver: <Exide> 71. ...Qxh5. Note that the rook on b1 is defended.

  An Englishman: Good Evening: I haven't recruited any silicon assistance, but does 69...Qb7 also work?

70.Qc2?,Bxg2; 71.Qxg2,Rb2 pins and wins.
70.R-2nd rank,Rh1X.
70.Rg1!,Rb2+; 71.Kh3,Bg2+; 72.Kg4,Qf3+; 73.Kg5,f6+; 74.Kg6,Qe4+; 75.Q/Rf5,Qe8X. What did I overlook *this* time?

Jan-16-09  patzer2: White solves today's Friday puzzle with the clever 69...Qd7!!, which utilizes a disguised pin to immobilize the Rook on g2 and threaten several possible mates (e.g. 70. Rd2 Rh1# or 70. Rg1 Rb2+ 71. Rg2 Rxg2+ 72. Kh1 Qh3# or 70. Re5 Rh1+! 71. KxR Qh3+ 72. Kg1 Qxg2#) or a winning pursuit after 70. g4 Bxg2 71. Kxg2 Qxg4+ 72. Kf2 Rb2+ 73. Ke3 Re2+ 74. Kd3 Qe4+ 75. Kc3 Rc2+ .

White tries 70. Qf2 to contain these threats, but the simple double attack 70...Qd1! wins due to the dual threat 71...Qh1# or 71...Qxh5 . For example, one possible continuation here is 71. Rg1 Qxh5 72. Rxb1 Bxb1 .

P.S. Like <An Englishman> I too am currently without the assistance of a Chess Engine, so I may have missed something (i.e. maybe a quicker forced mate in the 71. g4 line).

The short version of the analysis of today's solution is that 69...Qd7!! uses multiple threats to force a winning double attack after 70. Qf2 Qd1! .

Jan-16-09  MiCrooks: Interesting that this position BEGAN with a exchange sack on move 21!! Reminds me a bit of a game a friend of mine had against a GM in which he sacked his rooks to end up with minor pieces that totally dominated the rooks. I would have to imagine that White SHOULD have been able to defend and draw this game, but I don't think you can say he had an advantage at all. The Bishop was easily equal to a Rook in this position. King safety was the dominant issue.

I too went with Qb7 instead. Not sure if it work but thought it did, and I noticed another posted analysis of it but without silicon confirmation. When it comes to tactics these days it is hard to do without it!

Jan-16-09  ozmikey: <An Englishman> I think the problem with 69...Qb7 (which I thought was the solution too initially) is that it's not forcing enough in a position where White has mating threats as well. A good reply, for instance, would be 70. Re5 (threatening mate in two), when the best I can find for Black (operating without silicon assistance as well) is 70...Bc6 71. Re7 Qc8 (threatening 72...Rh1+) 72. Qf2! and White is OK.

  An Englishman: Good Evening: <oxmikey> seems to have found a very clever defense. You would think that only the White Queen can threaten the back rank, but 69...Qb7; 70.Re5! and the Rook and Queen trade jobs; the Rook menaces the back rank while the Queen threatens the h-file.

  agb2002: White is momentarily an exchange ahead and threatens 70.Qxc7 and Black's back rank.

If Black plays 69... Qxg3+ White won't play 70.Rxg3 because of 70... Rh1#.

If Black plays 69... Rh1+ 70.Kxh1 Qxg3 White won't play 71.Rg5 because of 71... Qe1+ 72.Kh2 (72.Qg1 Qxh4#) Qxh4+ and Black draws at least.

If Black plays 69... Qd7, threatening 70... Rh1+ 71.Kxh1 Qh3+ 72.Kg1 Qxg2#, White won't play 70.g4 because of 70... Bxg2 71.Kxg2 Qxg4+ with a winning attack.

Therefore, by elimination one gets 69... Qb7 threatening simply 70... Bxg2:

A) 70.Rg1 (any other move with this rook allows 70... Rh1#) Rb2+ 71.Kh3 Qd7+ 72.g4 Qd3+ 73.Rg3 Qf1+ 74.Rg2 Qxg2#.

B) 70.Qf2 Bxg2 71.K(Q)xg2 Rb2 pins the queen.

Hmm, I suspect this is too easy...

Jan-16-09  TheCap: Difficult? I think due to limited sensible moves by black this should be medium... Everybody agree???
Jan-16-09  patzer2: <TheCap> Perhaps the difficult part is visualizing ahead the quick shift from one set of double threats to another in two successive Queen moves (i.e. 69...Qd7!! 70. Qf2 Qd1! ). Also seeing that the tempting 69...Qb7 fails to 70. Re5! is not so easy.
Jan-16-09  BlackWaive: I spent slightly less than five minutes on this puzzle.

My first candidate was 69...♕d7, intending 70...♖h1+, 71...♕h3+, 72...♕xg2#. I could not find a valid response to 70. ♕f2; poor board vision prevented me from seeing 70...♕d1!, forking checkmate and the win of the rook (after winning back the exchange with 71. ♔h3 ♗xg2+).

I then moved on to 69...♕b7, and noticed that Black threatened 70...♖h1#. Furthermore, White's previous saving move 70. ♕f2 no longer applies because 70...♗xg2 71. ♕xg2 ♖d2 permits a winning Queen vs. Rook endgame. The other possessive move, 70. ♖g1, looks winning for Black after 70...♖d2+. I settled with this.

  agb2002: As pointed out by ozmikey and An Englishman, after 69... Qb7 70.Re5 seems to solve White problems. Another possibility is perhaps 70.Qd4 threatening 71.Qd8#.

My previous post looks to me now like an insult to logic. The necessary consequence is another botched job. :-P
