|Sep-23-17|| ||al wazir: I went with <34. Rxd6 cxd6 35. Qd5+ Kf8> 36. Qxd6+ Re7 (36...Kg8 37. Bxh6) 37. Rxg7+ Kxg7 38. Qxd7+ Kg8 39. Bxh6 Qd7 40. Qxf6.|
But this is the second time around for me.
|Sep-23-17|| ||wtpy: Altairvega, That is the line I chose.Re7 looks like only good defense. 37 Qd6 and black can't take bishop with 37 gh6 because 38 Qf6 Rf7 39 Qd8 Qe8 40Rg8 winning the queen.|
|Sep-23-17|| ||AlicesKnight: Not today for me, I'm afraid. Compare J Mason vs Winawer, 1882 for two-rook breakthrough including line and square clearance.|
|Sep-23-17|| ||nalinw: Fantastic set of sacrifices - if Kxh6 White seems to be left with almost nothing - but it is enough to mate ....|
|Sep-23-17|| ||drollere: 34. Rxd6 followed by Qd5+ was obvious. The second R sacrifice was the surprise; I would have played Bxh6 to open the file for the rook.|
|Sep-23-17|| ||jith1207: The interesting thing about the puzzle position is that black had all 8 pawns after 33 moves!|
|Sep-23-17|| ||goodevans: I've scrolled through nearly three pages of posts (not so easy on a mobile) and I can't find a definitive answer to <38...Rg8>. Did I miss something?|
|Sep-23-17|| ||Clement Fraud: I must be improving - if only a little: I quickly saw the the idea of vacating the d5 square for the Queen via the sacrifice Rd6, but I failed to see the forcing sequence. I was looking at 34.Bh6 gh6 & 35.Rd6 (white having opened the file for his Rook on the g-file, and the a2-g8 diagonal for his Queen).|

How about: 39. Qxf6+ Kh7 40. Qf7+ Kh8 41. Qf6+ Kh7 42. Qh4....
|Sep-23-17|| ||malt: Come up with 34.R:d6 cd6 35.Qd5+ Kf8 36.B:h6 Re7
(37.Qa8+ Qe8 spoils it)
Back to the board
|Sep-23-17|| ||malt: Second stab;
34.R:d6 cd6 35.Qd5+ Kf8 36.B:h6 Re7 37.Rg6
|Sep-23-17|| ||claudi: 36.Bf4 would be a fine move.|
|Sep-23-17|| ||malt: <claudi: 36.Bf4 would be a fine move.>
36...Re5 (36...Qd7 37.B:d6+ Re7 38.B:e7+ and 39.Q:c4)
37.Q:d6+ Re7 38.R:g7 K:g7 39.Q:e7 Kg8
|Sep-23-17|| ||Whitehat1963: Amazing king hunt!!|
|Sep-23-17|| ||Once: Way beyond my pay grade today.
Three piece sacrifices in a row? In my dreams, in my dreams.
|Sep-23-17|| ||steinitzfan: This game reminds me of yesterday's. Black just can't send any relief to the kingside and it's hard to see why except through brute calculation.|
|Sep-23-17|| ||newzild: I went for 34. Rxd6 cxd6 35. Qd5+ Kf8 36. Bf4 (instead of 36. Rxg7, which has too many variations to consider).|
Now 36...Rd8 runs in to 37. Bxh6!
|Sep-23-17|| ||Otoy: Eight moves in total to complete the combination. Patzers won't see that long. Sigh.|
|Sep-23-17|| ||BxChess: <Goodevans>:
39. Qxf6+ Kh7
40. Qf7+ Kh8
41. f6 Qd7 (what else?)
42. Bg7+ Rxg7 (42..Kh7 43. Q h5#)
43. fxg7+ Kh7
44. g8=Q+ and mate to follow.
|Sep-23-17|| ||patzer2: I was stumped and went for the flawed "win of a piece" in attempting to solve today's Saturday (34. ?) puzzle with 34. Rxe4? |
After 34. Rxe4? Rcxe4 35.Bxe4 Rxe4 36.Rxc5 bxc5 37.Qd5+ Kf8 38.Qxe4 Qxe2+ 39.Kg1 Qxa2 ⩱ (-0.56 @ 34 depth, Stockfish 8,) White emerges a Bishop up. Unfortunately, this "win of a piece" comes at too high a price, as Black gets four pawns for White's extra piece (i.e. the Bishop.)
So the best way for White to proceed is not to attempt to win material, but instead to win the under protected Black King with a surprise mating attack with 32. Rxd6!!
After 34. Rxd6!!, Black's strongest defense is apparently 34...Re5 +- (+5.19 @ 35 depth, Stockfish 8) when play might continue 35.Rd8 h5 36.Bxc5 Qxc5 37.Rd7+ Re7 38.Rxe7+ Qxe7 39.Qd5+ Kf8 40.Qxc4 hxg4 41.hxg4 Qd7 42.Qb4+ Qd6 43.Qxe4 Qd8 44.Qc4 Qd7 45.Bf3 Qe7 46.Qa4 Kf7 47.Qa8 Qe8 48.Bd5+ Kf8 49.Qxa3+ Qe7 50.Qa8+ Qe8 51.Qa6 Qd7 52.Bb3 Ke7 53.Qc4 c5 54.Qe4+ Kd6 55.Ba4 b5 56.Qd3+ Kc7 57.Bxb5 Qxd3 58.exd3 Kb7 59.a4 Kb6 +- (mate-in-17)
In the game continuation, after 34. Rxd6!! cxd6 35. Qd5+ Kf8, instead of the surprising double piece sham sacrifice 36. Rxg7! Kxg7 37. Bxh6+ +- (+6.45 @ 32 depth, Stockfish 8,) White has a stronger and slightly simpler continuation with 36. Bf4! Rd8 37.Bxh6 Qd7 38.Bxg7+ Qxg7 39.Rxg7 Kxg7 40.Qxc4 +- (+11.41 @ 30 depth.)
P.S.: For an early improvement for Black in the opening, instead of 4...Bb4, I prefer the currently much more popular move 4...d5 as in Black's recent win in the Super GM game Gelfand vs Wang Hao, 2017.
Later in the game, instead of the retreat 19...Ned7 allowing 20. b4 ⩲ (+0.31 @ 32 depth, Stockfish 8), the computer recommendation 19..exf3 20.exf3 axb3 21.axb3 Bb7 22.Nf5 Ra1 23.Nd4 Qd7 24. Bf4 Rxd1 25. Qxd1 Ng6 = to ⩱ (-0.12 @ 28 depth, Stockfish 8) looks more solid.
|Sep-23-17|| ||goodevans: <Boerboel Guy> 42...e3 and I'm not sure whether white has a win.|
<BxChess> "41...Qd7 (what else?" - How about YouRang's 41...Na4?
|Sep-23-17|| ||WorstPlayerEver: 34. Rd6 cd6 35. Qd5 Kf8 36. Bf4
2 minutes, not bad for a Saturday puzzle :)
|Sep-23-17|| ||WorstPlayerEver: <patzer2: I was stumped and went for the flawed "win of a piece" in attempting to solve today's Saturday (34. ?) puzzle with 34. Rxe4?>|
Yeah, first I had the same feeling eying at c5, but then I noticed White was a piece up ALREADY. Black seems to have sacked one. Thereafter the solution came almost instantly to me.
For the first rule is: look at all the pieces!
|Sep-23-17|| ||patzer2: <WorstPlayerEver> Thanks! Since White starts a piece up, I guess my flawed "win of a piece line" was actually a flawed simplification to keep the "extra piece" at too high a price (i.e. the four pawns Black gets for the Bishop after 34. Rxe4?)|
|Sep-24-17|| ||WorstPlayerEver: <patzer2>
To my surprize Stockfish plays the same line. I looked at Bh6 or Rg7 -as sole moves- for a split second, but didn't see the combination.
However, I spend only 1 a 2 minutes on a puzzle. Depends on the day. Since we are speaking of game continuations, I try to simulate time pressure that way.
I can recommend this method; I rarely run into long -wrong- analysis these days :)
After all, like Kramnik has stated before; it's all about building confidence. Lack of confidence is the greatest enemy of every chess player, I assume.
