Kibitzer's Corner
< Earlier Kibitzing  · PAGE 3 OF 3 ·  Later Kibitzing>
Nov-03-11  jackalope: Else <31. h5 ... 32. hxBg6>. Either way, White ends up with at least Black's bishop and an advanced pawn. Time to check...
Nov-03-11  jackalope: Typo - wrote White has "2 passed pawns"?? - need more coffee...
Nov-03-11  CHESSTTCAMPS: In this endgame position, white has a centralized knight plus pawn (with superior pawn structure) for a pinned, ineffective bishop. The trapped position of the white rook looks like a technical problem, but white is in position to force a quick victory.

The forcing 31.h5! at first glance appears to fall into a trap, but actually wins decisive material.

A) 31... Kg7 32.Rxg6+! fxg6 33.Ne6+ wins.

B) 31... Rxd4 32.cxd4 Kb5/b7 33.Rxg6+ fxg6 34.hxg6 Kxg6 35.Kf3 Kg5 36.d5 is a simple K&P ending.

C) 31... Kg5 32.Rxg6+! fxg6 33.Ne6+ Kxg4 34.Nxd8 and black's K-side pawns are easily stopped, e.g.

C.1) 34... gxh5 35.Nxb7 h4 36.Nc5 h3 37.Nd3 h2 (f3 38.Ne5+ followed by Nxf3) 38.Kg2 wins.

C.2) 34... Kxh5 35.Nxb7 g5 36.Kf3 g4+ 37.Kxf4 Kh4 38.Nd6 g3 39.Nf5+

Time for game review...

Nov-03-11  jackalope: Playing through this, I see <10... NxBb3+ 11. axb3 Qa5> instead of <10... Nfxe4>... Any merit to this?
Nov-03-11  Patriot: 31.h5 comes to mind instantly but you have to consider the potentially trapped rook after 31...Kg7 or 31...Kg5. 32.Rxg6+ fxg6 33.Ne6+ wins. So then I considered taking the knight:

31.h5 Rxd4 32.cxd4 Kg7 33.hxg6 Kxh6 34.gxf7 Kg7 35.Kf4 or 35.d5 or 35.g5 should win easily.

I don't see any other moves that might refute 31.h5 so it should be winning.

Nov-03-11  Patriot: Sorry, I meant 35.Kf3 (not 35.Kf4) in the 31...Rxd4 line.

I also wanted to mention even though a "win is a win", after 31.h5 Rxd4 32.cxd4 Kg5 33.Rh8 is possible although I prefer to get the pieces off the board with 33.hxg6 Kxh6 34.gxf7 etc. That's why I preferred 32...Kg7 because it seemed stronger. But interestingly, it may be best for black to play 32...Kg5 and allow white to go "wrong" and save the rook which gives black "something" to work with.

  kevin86: In one way,this is easier than a Monday puzzle...h5 is the solution.

Now if black tries to trap the rook via 31...♔g7 or g5,then 32 ♖xg6+ fxg6 33 ♘e6+ wins the rook and gains a piece.

  kevin86: How about this idea? 31...Rxd4 32 cxd4 Kg5 33 d5!! and the pawn will queen!}
Nov-03-11  Max of Tat: <kevin86: How about this idea? 31...Rxd4 32 cxd4 Kg5 33 d5!! and the pawn will queen!>

33. hxg6 Rxh6 34. gxf7 Kg7 35. Kf3 seems just as decisive.

Nov-03-11  SuperPatzer77: <Max of Tat> Yes, you're absolutely right about that. Simplification by White helps turn this game into the easy pawn endgame for White.

<Max of Tat> You've made a typo - 33. hxg6 Rxh6 (typo - it should be 33...Kxh6), 34. gxf7 Kg7, 35. Kf3

its not that easy, h5 pinning the B doesn't look so good after Kg7. it only starts to look good upon second look when you realize you can sac the rook and set up Ne6+ forking the rook at d8

I for one really appreciate the work chessgames is doing on the daily puzzles and suggest instead of complaining about the puzzles you should find another website you like more.

Nov-03-11  Marmot PFL: Nice tactical shot, somewhat diminished as a puzzle since 31 g5+ and 32 h5 also wins easily, if not as fast.

Psychologically Anand never seems to recover from the awful 19...Rd5?

Nov-03-11  benjaminpugh: That was too easy for a Thursday.
Nov-03-11  mrcountman: Even I came up with h5, so I seriously doubt this is "Thursday worthy"
Nov-03-11  Patriot: <<mrcountman>: Even I came up with h5, so I seriously doubt this is "Thursday worthy"> 31.h5 is very easy to see but is not sufficient as a solution unless you can handle black's challenge (31...Kg7/Kg5 or 31...Rxd4). In my opinion the 31...Rxd4 line helps bring it closer to Thursday.
Nov-03-11  DoctorDre: Not too hard for a thursday
Nov-03-11  rapidcitychess: A little too easy to be honest. I could accept this as a Tuesday puzzle.
Nov-03-11  TheBish: Judit Polgar vs Anand, 1991

White to play (31.?) "Medium"

White is up a pawn, but it's a doubled b-pawn. Black's f4 pawn is weak. The pin by White's rook on Bg6 looks strong, but 31. h5 looks to be easily met by 31...Kg5 (Kg7). Or is it? One needs to look deep into the position to find the truth!

31. h5 Kg7

It doesn't matter if Black tries 31...Kg5; the result is the same.

32. Rxg6+!

For some reason, this took me a while to see. I was analyzing 32. hxg6 Kxh6 33. gxf7 Rf8 (or 33...Kg7?? 34. Ne6+ wins, as does 33...Kg6?? 34. Ne6) and trying to push a square peg into a round hole!

32...fxg6 33. Ne6+ and wins after 34. Nxd8.

The only other try for Black (after 31. h5) is 31...Rxd4 32. cxd4 Kg7 (Kg5) 33. hxg6 Kxh6 34. gxf7 Kg7 35. Kf3 Kxf7 36. Kxf4 with two passed pawns and an easy win.

Nov-03-11  Everett: First move looks like a red herring, but the sting comes if you see the knight fork on e6. What makes this more special is the correct assessment of the endgame line arising after 31..Rxd4 32.cxd4 Kg7
Nov-03-11  stst: Taking advantage of the pin of the B, the quiet but effective move would be 31.h5 Kg7
32.g5 Rd5
33.hxg6 fxg6
34.Ne6+ Kf7
35.Nxf4 Rd2
36.Kg3 and Bk has no good move to survive W's potential pass pawn and the extra N.

  kevin86: <newton>I wasn't complaining,what I was saying is that the key move APPEARED to be very obvious discovered,while in fact it was more complex that that.
Nov-14-11  njchess: At 19. f4, the position slightly favors White but only in the short term. White has more space with her knight threatening Nf5+, or even f5 putting more pressure on the e6 pawn.

Black has the half open c-file staring down at White's king and the bishop which could be more useful in the endgame than the knight. Black's pawn structure is marginally better with the kingside majority to White's doubled queenside pawns. Black has some long term strength's but nothing compelling, and he needs to deal with an attack from f5 whether its the pawn or the knight.

I'm sure Anand was thinking about doubling the rooks up when he played 19. ... Rd5?? but it loses material and the position instantly. Oddly enough, the odd looking Kf6 is probably Black's best move at this point, with a drawn position likely.

Jul-11-17  LA MAN: On move 12 white. I favor bxc3. then after black qxb. White NF5. this is just a quick thought but who knows if it is good.
Jul-11-17  DWINS: <LA MAN>, After 13.Nf5, Black simply takes the knight and White is completely lost.
