Dec-04-09  YouRang: I would have to rate this as the easiest set of Mon-Fri puzzles that I can recall.

A couple of moves quickly pop into mind, but they are just as quickly popped out:

[1] Take the queen with 44.Bxc8? -- but it's no good since it leaves f1 unguared, allowing the 44...Rf1+ skewer: 45.Ke3 Rxf6 46.Kxd3 Rxf7 leaving white with a losing exchange-down endgame.

[2] Promote the pawn via 44.f8=Q? -- it threatens a quick mate and leaves black little choice but to check first via 44....Qc2+. Unfortunately for white, this results in a quick mate for black: 45.Ke3 Qe2+ 46.Kf4 Qe4#.

So, the most natural move to consider is promotion *with check* via <44.f8=N+>.

After this, it's just a bunch of forced/forcing moves: <44...Kg8 45.Be6+ Qxe6 46.Qxe6+ Kxf8 47.Qxd5> and we have Q+pawns vs R+B+pawns. Given that black's king is so exposed and that white has a passed d-pawn, white should have little trouble winning.

Dec-04-09  BOSTER: <CG> continues to check how we have studied the lessons <underpromotion>. So... we are playing with knight again.
44.f8=N+ Kg8
45.Be6+ Qxe6
46.Qxe6+ Kxf8
47. Qxd5 and white have winning position.
And this is another good lesson for players who likes <Material even routine> ,which show that in chess most important not material ,but position and right to move.
Dec-04-09  zanshin: <Sneaky: I don't think so much that it's an easy week, it's just that CG is following this obvious promoted-pawn theme, now so any pawn push that might turn into a queen (or something else!) we immediately jump upon.>

I agree with <Sneaky>, but I also like this puzzle-theme idea. It must take more work from <CG> but I find the concept more fun and educational.

Dec-04-09  werty: Hey! Hey!(DOM)will you and (ONCE) cut out those snide remarks about Betty remember here in England she is a "sacred cow" Also don,t count out Charlie.But Ido like our new term
Dec-04-09  GreenFacedPatzer: Hmmm...

I considered 44 f8=N+, but thought it was busted after

44 ... Qxf8
45 Qxf8 Rf1+
46 Ke3 Rxf8
47 Kxd3 ...

leaving black with a R vs B endgame. In the end, I didn't see anything better for white than 44 Qe7 (with multiple threats.)

Can someone point out to me how white _should_ respond if black defends 44 f8=N+ with 44 ... Qxf8? It seems that I'm missing how white's attack continues after that.

Dec-04-09  Patriot: <<GreenFacedPatzer>: Can someone point out to me how white _should_ respond if black defends 44 f8=N+ with 44 ... Qxf8? It seems that I'm missing how white's attack continues after that.>

Try 45.Qxf8 and if in your line, 45...Rf1+??, then 46.Bxf1

Dec-04-09  lost in space: Today with nearly no time: The first move 4. f8=N+ is very obvious. All the rest was not tranparent for me
Premium Chessgames Member
  beenthere240: The x-ray attack beginning ...Rf1+ only works if whites bishop on h3 moves (for example if white plays 44. Bxc8?) This is why 47. Qsd5 is essential to avoid 47. ...Rf1+ 48. Ke3 Re1+, winning the Queen). Keres had to see the whole combination when he played 40. Rc8 which gives up a rook.
Dec-04-09  MaczynskiPratten: Frustrating! I saw 44 f8=N+ but like <GreenFacedPatzer> missed that after 44..Qxf8 45 Qxf8, Rf1+ is not a threat. Why? Maybe because I'd been looking at lines with Bxc8 and saw that Rf1+ then won.

I plumped for 44 Qe7 which at least deserves consideration. There is now a devastating threat of 45 f8=Q+. So 44..Qc2+ 45 Kf3! (not Ke3 Qe2+) Be4+ 46 Kf4 Qf2+ (or Qd2+) 47 Ke5! hiding behind Black's pawns and bishop! I suspect Black's best is 45...Qd1+ 46 Kf4 Qd2+ 47 Ke5 Qe3+ 48 Kd6 Rb6+! 49 Kd7 Rb7+. Maybe it's the need to rule out alternative lines like this which lead to the "difficult" rating for tonight's puzzle, because 44 f8=N+ is easy to see, though I didn't choose it!

Dec-04-09  PinnedPiece: Maybe I missed some complication, but this seemed like the easiest Friday puzzle I've tried in two years.
Dec-04-09  GreenFacedPatzer: <Patriot> Thanks for pointing out the obvious response to 45...Rf1+ after 44 ... Qxf8. I have the oddest blindness sometimes. Somehow Rf1+ got lodged in my head as black's most pressing threat in several lines, and I simply didn't recognize that it didn't apply in this case.
Dec-04-09  Patriot: <GreenFacedPatzer> No problem. The reason could be as <MaczynskiPratten> pointed out. I've done it myself before.
Dec-04-09  WhiteRook48: I had 44 f8=N+ it was so obvious!
Premium Chessgames Member
  beenthere240: <MaczynskiPratten> I've found that solutions beginning with quiet, non-forcing moves like 44 Qe7 are rarely correct, especially if they allow a forcing (checking) responses -- not only 44...Qc2+ but also 44...Rb2+ when the king can easily wander into disaster. Actually in this puzzle, for me, the realization that the bishop HAS to stay on h3 to prevent Rf1+ was the key to the solution.
Dec-04-09  BOSTER: <patzer2> <For novices several lesson can be learned from this one puzzle>. <patriot> <Excellent advice>. But I doubt that he read this, if he did he would ask you <6.When faced with ...44.Nf8=Q+! > -what does it mean? Sometimes novices are very curious creatures.
Dec-04-09  Patriot: <BOSTER> You doubt I read <patzer2>'s comments? I saw the Nf8=Q+ but knew what he meant. I'm not sure what your point is.
Dec-04-09  SufferingBruin: 1000 rating, trying to get better.

I got it. I don't mean just a little. I mean, I nailed this one. Either I'm getting better or the puzzles this week are easier than usual. I'm going with the former. :)

I looked up Furman in the world according to Google. He was, as his bio states, Karpov's trainer. I was looking for information on Google and came across an article about the Karpov-Korchnoi world championship match. In the article, it makes note of Furman's death three months before the match and also lists the seconds for both players. I can't find the article, by the by--laziness after a full meal (poster looks for article, checks again, hears the dinner bell, says the heck with it...).

Anywho, one of Karpov's seconds was Tal. Yeah, that Tal. And the article noted that Tal and Korchnoi had a long-running feud.

Is this true? Tal and Korchnoi no likey each other? Just curious...

Dec-04-09  MaxxLange: <SufferingBruin> you are getting better! no doubt. it feels good, doesn't it?

even 15 minutes a day of concentrated effort, like one does in solving the daily puzzle, is so very good for improving. It's like learning a instrument: practice every day is critical. A training program of relatively short daily practice, like an hour, done without almost ever skipping a day, is better than irregular, special long study binges mixed with periods of not studying.

Dec-05-09  TheaN: Friday 4 December 2009 (on 5 december)


Target: 6:00;000
Taken: 3:01;873 (!)

Material: Black up, ♖ vs ♙(!)

Candidates: f8=Q, f8=N†, Qxg6†, Bxc8, f8=Q... <[f8=N†]>

Typical position. White is a Rook down for a pawn on f7, which can immediately promote. At first I thought 44.f8=Q could be met by 44....Qxf8 45.Qxf8 Rf1†. As such, I thought f8=N† met the same capture (Qxf8). I started to look at other bizarre moves for White. After I noticed that Black couldn't play Rf1† due to 46.Bxf1, I looked why 44.f8=Q was bad, noticing 44....Qc2† with mate. As Bxc8 as bad too, as then Rf1† is available, I ran out of moves. Only then, I noticed that the Knight promotion is the only winning move:

<44.f8=N†!> it's the only forcing move that gains material. Capturing with the Queen is not dangerous for White, he can just take back. As such:

<44....Kg8 45.Be6†!> the problem of Bxc8 was and is that that allows Rf1†, however, now the Black has to take the Bishop instead, leading to:

<45....Qxe6 46.Qxe6† Kxf8 47.Qxd5 > and White should be able to win this endgame. Time to check.

  Domdaniel: <werty> I actually consider myself a fan of Betty aka Brenda Windsor, or whatever The Queen is called in private. Such talk used to be considered treasonous here in Ireland, but we're cool with royalty now. And we'd love to see her pay a visit.

Admirable woman, really. Seen off about forty prime ministers, from Churchill to Thatcher to that dour Scottish bloke with a magnetic attraction for bad advice. Compared to her politicians, HM is the best argument going for hereditary heads of state.

America should try it, don't you think? It would create a nicely useless niche for the Bush or Kennedy clan and stop them from constantly running for office. With all the hanging pawns and hanging chads - not to mention lethal injections - that go with it.

BTW, I'm sure you know about the current TV drama with five different actresses playing Betty at different stages in her life. Some impertinent journalists had the gall to phone the palace and ask which one she liked best, but they were told to sod off.

Quite right. Not so long ago they'd have been clapped in the Tower. Bloody peons.

Dec-06-09  sethoflagos: With dangerous mating threats on both sides, the key probably lies in taking and maintaining the initiative with a forcing sequence.

44 Bxc8 Rf1+
45 Ke3 Rxf6 for a losing B vs R endgame.

44 f8=Q Qc2+
45 Ke3/f3 Qe2#

So 44 f8=N+ Kg8
45 Bxe6+ Qxe6
46 Kxf8

  perfidious: Could Keres have considered the gambit idea 6....b5 7.cxb5 cxb5 8.Nxb5 Qb6 9.Nc3 Bb4?
Premium Chessgames Member
  Penguincw: e6 breaks through the position.
Premium Chessgames Member
  plang: This line was relatively unexplored at the time; 6 Nc3 was already a new move. 11..Nfd7 was suggested as an improvement aiming for simplification. 28 Nd7..Rxd7 29 Bxd7..Qe7 would have given Black counterplay for the exchange. White had to avoid 53 Kh4?..g5+ 54 Kh5..Rh3#.
Apr-05-22  cehertan: You know your national championship is strong when the great WC Candidate Keres gets manhandled like this.
