|Feb-14-19|| ||Penguincw: Happy Valentine's Day.|
|Feb-14-19|| ||1stboard: I knew this game and the solution when I saw it. This game is in Chernev's 62 most instructive games of chess|
|Feb-14-19|| ||1stboard: White's 43 Nd7+ followed by 44 Nb8 nicely shuts on the rook and the pawn becomes a queen on move 45. Important that white takes the rook on a8 and not g8 on move 42|
|Feb-14-19|| ||whiteshark: A compulsory winding-up|
|Feb-14-19|| ||Cheapo by the Dozen: I reversed the order of Nd7+ and Rxa8, for the plan with Nb6 rather than Nb8. That wins resoundingly too.|
|Feb-14-19|| ||malt: Have 38.R:a6 R:a6 39.Rb7 Rg7 40.Nd7+
looked at 38.Rb7 Rg7
(38...B:b7 39.cb7 Rab8 40.Nd7+ )
|Feb-14-19|| ||malt: In my 38.Rb7 Rg7 39.R:g7
39.Nd7+ Ke7 40.Nc5+ B:b7 41.cb7 Rb8
|Feb-14-19|| ||ChessHigherCat: At first I was hoping to take advantage of the mating net with the knight, but after seeing Rxa6 Rxa6 c7 Ra8 I decided to settle for the exchange, like this:|
38. Rxa6 Rxa6 39. c7 Raa8 40. Rb8 Raxb8 41. cxb8=Q Rxb8 42. Nd7+ Ke7 43. Nxb8
which eventually wins but it's veeeeeerrryyy sloooooooooow:
Kd6 44. Kf2 Kc7 45. Na6+ Kb6 46. Nb4 Kb5 47. a3 Ka4 48. Nc2 Kb3 49. Ke3 h5 50. h4 Kc4 51. Nd4 Kc3 52. Nxe6 Kb3 53. Nd4+ Kxa3 54. Nxf5 Kb4 55. Kd4
|Feb-14-19|| ||patzer2: Found myself enjoying the wisdom in <Random Visitor>'s 2009 post:|
<Once: <SufferingBruin> Enjoyed your post, as always. Very well written and funny.
If you stick with it, a funny thing will happen. You will get better. Problems that currently elude you will become ridiculousy easy. You will spot the key move much more quickly. Tactics and themes will suggest themselves. Some grandmasters talk about the move that the position demands - an instinctive pull to the right solution, or at least a very tempting one.>
My youngest Grandson was born in February 2009, and will be 10 years old this month. I taught him to play when he was four years old, and have helped coach him since then.
Much of what <RV> wrote about persistence and determination applies to my grandson's progress. He was a USA top 100 player as an 8-year-old, and this past year he improved over 200 rating points and is now a solid class C player.
In November, 2018, he beat a class A player and a class B player in a local city swiss tournament to score 4 out of 5 and tie for second place.
In January of this year, he took first place in the high school section of a tournament in Fort Worth, Texas with a perfect 5-0 score. Last week, he and his brother (age 13) and a friend (age 14) won the first place high school division team trophy in the Region 2 (28 county region including Fort Worth and Waco) Texas scholastic championship. In the regional championship, he scored 4.5 out of 6 (only one loss to a 1600 player) to take fifth place overall -- not bad for a 9-year-old competing against 15 to 17 year-old players.
P.S.: Perhaps the part about determination and persistence applies more to my 13-year-old grandson, who has more of a talent for writing and language than Chess. For him, as compared to his younger brother, the Chess learning curve has been more of a challenge. Even so, he has stuck with a regular program of daily chess study, and as a result he scored three out of six in the regional high school championship last week and has seen his rating improve over 300 points in the past year.

|Feb-14-19|| ||TheaN: Thursday 14 February 2019
For Thursday Valentine's Day 2019 we have a repeat of a <Saturday> puzzle from 2009... I commented on this game then (which I rarely did in the weekends), and I do think all that analysis holds up, so I won't bother myself with more of myself. Although, I did want to play slightly different moves than my own self:
1) I did intend the entire game line instead of 42.Nd7+?! in 2009: 42....Ke7 43.Rxa8 Kxd7 44.Rxg8 Kxc7 +-. It's not changing anything, the game line's just faster because White will promote instead of being a rook up.
2) However, after the 37....Rf8 defense I somehow settled on 38.Nd7+ Ke7 39.Nc5+?!, winning only the bishop, instead of 39.Nxf8+! in 2009 which forcefully wins the rook after 39....Kxf8 (otherwise the Knight's just there) 40.c7 Rc6 41.Rb8+ with c8=Q.
Human mind and its 'progress'. Weird.
How to look at this puzzle for chess progress in general though?
A Saturday ten years ago becoming a Thursday now, is this a trend where the current chess world simply calculates more, has more sources at their disposal to become better and be more adapt at tactical calculations?
The puzzle may be between regular Thursday to Friday level... Saturday seems too excessive for what's basically an endgame combination. Took me long enough ten years ago though, little bit less now :>.
|Feb-14-19|| ||King Harvest: <goldfarbdj:... the main thing I want to point out is that comment from chrisowen, from nine years back. I knew he was getting worse over time, but....!!!!>|
Wow. That blows up my theory that <chrisowen> is a chessgames cipher/super-puzzle.
|Feb-14-19|| ||eyalbd: I calculated this:
<38. ♖xa6 ♖xa6 39. ♖b7 ♖g7 40. c7 ♖a8 41. ♖b8 ♖g8 42. ♖xa8 ♖xa8 43. ♘d7+ ♔e7 44. ♘b6> which wins a piece and the game but missed the much stronger <44.♘b8!>
|Feb-14-19|| ||RandomVisitor: <patzer2>Thanks for the compliment, but that quote was from <Once>, once upon a time.|
Funny that many moves win here:

As you note, the wise words expressed here about the value of persistence and determination in Chess should be attributed to <Once>.

|Feb-21-19|| ||goodevans: My, oh my! Was it only a week ago we had this puzzle? How time flies.|
At least I was clued up enough to remember the 'solution'. Last week I went with one of the other winning moves.
|Feb-21-19|| ||HeMateMe: tricky. You know that RxB is the first move, but it's more natural to then think of putting the white Rook on the 8th rank, after c7, but that's too slow. The sneaky threatened mate on f7 gains white a tempo and the win.|
|Feb-21-19|| ||devere: It's deja vu all over again.|
|Feb-21-19|| ||Jimfromprovidence: Try this puzzle as an alternative to today's repeated one. It's from Linares 2010. White to play and win. Move 57.|
