|Jun-17-05|| ||AwesomeMorphy: I got this right!|
|Jun-17-05|| ||chessgames.com: Yes, this one is relatively easy for a Friday, as there are some alternate ways to play the attack.|
If you were intending 28.Nxh7+ take full credit, as that wins too. (We can let crafty show us the details.)
However, only partial credit if you were planning 29.Qg7+. While it leaves white with a fair advantage, it's vastly inferior to 29.Re1! which wins on the spot.
|Jun-17-05|| ||Akavall: Hehe, I solved the puzzle, but never seen the that white king was being checked, I guess 26. Rxd4 is too obvious.|
|Jun-17-05|| ||Greginctw: "If you were intending 28.Nxh7+ take full credit, as that wins too"|
would 28. NXh7+ be worthy of ?
as it doesnt give mate? How can anything be comprable if it doesnt lead to mate like Qxh7 does. You cant afford full credit unless it leads to mate like the main line.
|Jun-17-05|| ||jahhaj: Well I didn't see 29. ♖e1, in fact I didn't consider anything at all after Black's 28th move. I had the position in my mind and just thought obviously winning for White. Do I get full credit? I'm sure I would have played 29. ♖e1 OTB as well all the other moves.|
|Jun-17-05|| ||crafty: 28. ♘xh7+ ♔e8 29. ♘xg7+ ♔d7 30. ♕f5+ ♔c6 31. ♕xf7 (eval 2.56; depth 14 ply; 750M nodes)|
|Jun-17-05|| ||al wazir: 29...Ne5 30. fxe5 Ke8 31. e6! fxe6 (31...Rc7 32. Qg8#) 32. Rxe6+ Kf8 33. Qg7#.|
|Jun-17-05|| ||Marco65: Wow, I solved a Friday puzzle!
<al wazir> 29...Ne5 30.Qh8#
|Jun-17-05|| ||Marvol: <Marco65: Wow, I solved a Friday puzzle! >|
Hey, you stole my line :-)!
|Jun-17-05|| ||jipou: I suggest on 26 Rxd4 Kh8, isn't that better than taking the rook D4?|
|Jun-17-05|| ||DanRoss53: I was just about to say the same thing <jipou>...I think 26. ♖xd4 ♔h8 27. ♘f6 gxf6 28. ♕h6 ♖g8 29. ♖d7 ♖cf8 is still a won game for White, but at least gives Black fighting chances.|
Like <boofi>, <SnoopDogg> and <Akavall> I also didn't notice the check, but I still found the winning moves up through 28. ♕xh7. I agree with <jahhaj> that full credit should be given for that much of it.
|Jun-17-05|| ||patzer2: Here is an expanded version of today's 26. Rxd4! solution using Crafty 19.1:|
<26. Rxd4! cxd4> This is obviously forced. But seeing the next move requires a bit more skill. <27.Nf6+!!> Not 27. Nfe7+?? Kh8 28. Nxc8 Qxc8 29. Nb4 d3 30. Rd1 d2 31. Kf1 Qc3 32.
f5 Ne7 33. Na6 Nd5 34. Kg1 Ne3 with Black turning the tables and winning. <27... Kf8> Leading to a quick mate for White is 27... gxf6 28. Qh6 <28. Qxh7
gxf6 29. Re1!> A complicated (actually an unnecessarily over complicated option due
to the superior 29. Re1!) but pretty winning alternative, with a lot of instructive
pursuit combination possibilitiess, is 29. Qg7+!? Ke8 30. Re1+ Kd7 (30... Ne5! 31. Rxe5+ Kd7 (31... fxe5?? 32. Qxe5+ Kd7 (32... Kf8 33. Qh8#) 33. Qd6+ Ke8
34. Qe7#) 32. Qxf7+ Kc6 33. Ne7+ (33. Qxf6+ Kb7 34. Nd6+ Ka6 35. Nxc8 Qxc8 36.
Qe7 d3 37. Qa3+ Kb7 38. Re7+ Rd7 39. Qd6 Qc1+ 40. Kf2 Rxe7 41. Qxe7+ Ka6 42.
Qe4 d2 43. Qd3+ Kb7 44. Qd7+ Ka6 45. Qa4+ Kb7 46. Qd7+ Ka6 47. Qa4+ Kb7 48.
Qd7+ = with a draw by threefold repetition of moves.) 33... Kd6 34. Nxc8+ Qxc8 35. Qxf6+ Kc7 36. Re7+ Kb8 (36... Rd7 37. Qe5+ Kb7 38. Qd5+ Kc7 39. Rxd7+ Qxd7 40. Qxd7+ )) 31. Qxf7+ Kc6 (31... Ne7 32. Rxe7+ Kc6 33. Qc4#) 32. a4 b5 33. Qxg6
(33. Qxf6+ Kc5 34. Nd6 Rxd6 35. Rc1+ Kb4 36. Qxd6+ Kxb3 37. Qe6+ Rc4 (37...
Kxa4 38. Rxc8) 38. axb5 Qc8 39. Qxc8 Rxc8 40. Rxc8 d3 41. Kf2 Ne7 42. Rc7 Nd5 43. Rxa7 d2 44. Ke2 Kc2 45. Ra2+ <29... Ne5> Only delaying White's mate for a few moves is 29... Qe4 30. Rxe4 Ne7 31. Qg7+ Ke8 32. Rxe7# <30. Qh8# 1-0>
For want of a better classification, I'm putting 26. Rxd4! under my attack on the weakened castled position collection.
Note that Black could have avoided weakening his castled position, and could actually have maintained a small advantage with the defensive move 25...Qc6! .
|Jun-17-05|| ||benveniste: <DanRoss53>, I get the following continuation of your line:
30. Nd6 Rg7; 31. Rg7 Rb8; 32. Rxf7 Rbg8; 33. f5 Ne5; 34. Qxe6 Qd5; 35. Rxa7. Black can threaten perpetual check to force an exchange of queens, but ends up down an exchange plus a pawn.|
|Jun-17-05|| ||cu8sfan: Thanks, <patzer2> for your comments.|
|Jun-17-05|| ||xxdsdxx: Got it - fianlly. My way of thinking this through. Nxd4 ultimately loses both white Knights and leaves white a Knight down. Blocking the check with Nd5-e3, leads to a trade down where Black is up a pawn. Kh1 or Kg2 loses the Knight and puts the King in check. Rdxd4 c5xd4 Ne7+ NxN NxN+ forks the rook. QxN Qxh7 Re1 and chances look even. Nd5-f6+!! g7xf6 Qh6 and mate (Qg7)can't be stopped. Ignore the Knight and move Kf1 and Qxh7 leads to Qh8# which is also unstoppable. OTB the probably would have went with the Knight fork and neglected the Knight superficial sacrifice. These puzzles will make me consider each avenue prior to jumping into the street. GG - Good Puzzle (GP).|
|Jun-17-05|| ||YouRang: Woo hoo! After missing the Tue-Thu puzzles, I got the Friday puzzle.
Okay, it was easy for a Friday (the check kind of forces things, and it was clear that we had to take with the rook to keep up the attack with the knights). Still, I needed the morale boost.|
|Jun-17-05|| ||kevin86: Nice four move process:
1 get out of check and eliminate black's strong bishop.
2 check with a knight-though in harm's way its capture would lead to inescapable mate.
3 threaten mate by queen and pre-spoken knight.
4 use rook to seal the e file from escape.
|Jun-17-05|| ||DanRoss53: <benveniste> Indeed. It appears the best line is 26... ♔h8 27. ♘f6 gxf6 28. ♕h6 ♖g8 29. ♖d7 ♖cf8 30. ♘d6 ♖g7 31. ♖b7 ♖b8 32. ♖xf7 ♖bg8 33. f5 ♘e5 34. ♕xf6 ♕d5 35. ♖e7 ♕d4+ 36. ♔g2 ♕d2+ 37. ♔h3 ♕xh2+ 38. ♔xh2 ♘g4+ 39. ♔h3 ♘xf6 40. ♘f7+ ♖xf7 41. ♖xf7, but at least 26... ♔h8! gives Black some chance of survival (in hopes that White will play imperfectly).|
|Jun-17-05|| ||patzer2: <DanRoss53> <benveniste> Good observation on 26...Kh8!? as a good defensive try in a bad position.|
However, after <26... Kh8!? 27. Nf6 gxf6 28. Qh6 Rg8 29. Rd7 Rcf8 30. Nd6 Rg7 31. Rb7 Rb8 32. Rxf7 Rbg8 33. f5 Ne5 34. Qxf6 Qd5>, White wins with 35. Rxa7! Qd4+ 36. Kg2 Qb2+ 37. Kh3 Qxh2+ 38. Kxh2 Ng4+ 39. Kh3 Nxf6 40. Nf7+ Rxf7 41. Rxf7 Nd5 42. Rd7 Nf6 43. Rb7
(Fritz 8 assesses +4.94 @ 15 depth).
|Jul-03-16|| ||kereru: By all accounts Dus Chotimirsky was a bit of a character.|
|Jul-03-16|| ||WannaBe: Cheech had some great lines in the movie, unfortunately I can't post any of them. =))|
|Jul-03-16|| ||morfishine: This "play on word" collapses under its own imbecilic weight|
No explanation needed

Playing over this game today made me think, hmm 26.? White to play and win would make a good Friday puzzle.
I am only 11+ years too late with the idea :)
Happy Independence Day, America!!!
|Jul-03-16|| ||cunctatorg: Not bad at all for a seventy years old International Master; not bad at all!...|
|Jul-05-16|| ||kevin86: Comical how black's heavy pieces are so staid while white's are so powerful. Mate is inevitable.|
