Lost in translation

I stumbled upon a slightly interesting endgame position analyzing one of my games from the USATS. The position in question never even came close to appearing in the game, and the position I'm presenting below has been modified further for clarity's sake. (I'll be using the Nunn Convention for my analytical symbols.)

Analysis position

White to move & draw

The important line runs 1 Ke4! Obviously White's king has to get within the square of the g-pawn. Kf7 The clearest line. 2 Kd3! White remains within the square of the g-pawn. g3 3 Ke2! e4 Or 3...g2 4 Kf2! e4 5 Kxg2 Kf6!= 4 Kf1! 4 Ke1? throws the game away. Kf6 5 Kg2! Kxf5 6 Kxg3!=.

What makes this slightly interesting (but just slightly) is that, as in so many cases, a slight shift changes the assessment completely. If all the pieces were moved down one rank, Black wins easily.*

Analysis position

White to move now loses

Here 1 Ke3 Kf6 2 Kd2 takes the White king out of g-pawns square.

Endgame books are littered with an uncounted number of examples where a shift by a file or rank makes all the difference in the world. And these things really do come up in our own games fairly frequently.** Being able to spot such differences several moves ahead in your analysis, and assess them correctly, will earn useful half-points over time. 

* In the original analysis position, moving everything one rank up would have given White good winning chances in a Q+pawn endgame.

** Except for rook & pawn versus rook endgames. For all the emphasis placed upon them, those pretty much never come up, at least in my experience!

Good morning chess friends! Let's solve a simple position ! White to play and win! 

 

Just giving the first move is not enough! No, I did not figure this one out myself. Ain't chess grand?

USATS: My journey

I'll need to talk to the rest of the team as a whole before I can give more than the thumbnail description that I gave in the earlier post. One additional point I can make is that every single half-point we scored mattered. Without any of them we wouldn't have won.

As for me, this tournament was a mixed bag, results-wise, but quite promising in terms of how I played. In the first round, I played up over 400 points. A loss was the expected result, and I did lose. Fast. I believe my game finished some 30 or 40 minutes before the next game finished. I played the losing move after my opponent's eleventh move, though I played on until move 23. (I had black.)

Chess on YouTube

YouTube.com has a lot of chess videos these days. For example, GM Simon Williams even has his own channel. Here's his latest video, on his game against GM Nigel Short at the Bunratty Chess Festival from last weekend.

BRRRRR!

THE HUMAN HORIZON EFFECT

OR

WHY YOU SHOULD NEVER ACCEPT YOUR OPPONENT'S VERSION OF REALITY

Going over games with a computer after a tournament is always enlightening, but not always fun. In this game, I had a very nice attack, but the move that I thought was awesome, 25. ...Rxh3 (and which my friend Garry Day also found when seeing it later) does not actually work!  At the time, the move seemed like a game-ender, and Sam believed the same illusion that I did-but neither one of us looked far enough.

The moral? Even when you see the coming Apocalypse, look for the post-apocalyptic silver lining!

 I also found the game that was my inspiration for the plan, and I included it in the notes. Here it goes:

United States Amateur Team South, 2016 edition

The 2016 edition of the USATS was held in Tampa, Florida from February 12-14. I'll post more on the tournament later (perhaps even a comment or two about the hotel we stayed in, but probably not), but for now I just want to record that the Clermont Chess Club sent three teams to the tournament, and that we did well.

Our highest rated team was Clermont Chess Club Great Britain Chapter (1785.3 avg.). The team consisted of Tim Bowler and Connor Eickelman from the club itself, and club friends Wayne Strickland and Theo Slade. (Theo and Tim are from Great Britain originally, hence the name.) They had tough pairings, playing two of the top teams, but were still in contention for the Under 1800 prize in the last round. [ADDED: I should note too that Theo played a very tough schedule, against three masters and two experts. Included among the masters were John Nardandrea, who once again led the winning team, and FM Mark Ritter, who won the prize for Best Score on Board One. That was a murderer's row with an average rating of 2163 on the wall chart. That may be the toughest schedule anyone faced in the tournament. I know he was disappointed he only scored 2.5, but overall that was a good total.]

Our second highest rated team was the Clermont Chess Club Pine Hills Original Gangstas Chapter (1777.0 avg.). (Don't ask about the name, or we might tell you.) That team consisted of club regulars Jim McTigue, Paul Leggett, Garry Day, and myself. Somehow we managed to win the Under 1800 prize, no thanks to a late Round 5 meltdown from yours truly. (More on the games in later posts.) The incredible thing to me was that we were actually the leading team for the prize after the fourth round. Still not sure how that happened, but someone's got to win!

And in the Under 1500 division, the Clermont Chess Club Grand Fenwick Chapter (1227.8 avg.) won the Under 1300 prize convincingly with 3.5 match points. The final standings haven't been posted yet, but they had to have been close to finishing third overall. [CORRECTION: The team had three match points and finished in a tie for 5-7 overall. 3.5 mathc points would have tied them for first!] This team consisted of David _H_ Raymond (OUR Dave Raymond, the good one!), Norm Meintel, John Wolfe, and Thomas Lee Johnson. Again a team of all regulars, and I'm particularly pleased with this team's accomplishments. Thomas is fairly new to competitive chess and only had 11 rated games prior to the tournament. John is coming back from a decades long lay-off from the game, though he had two other tournaments under his belt from recent months. It had been two & a half years since Dave played in a tournament prior to his return two weeks ago, and Norm hadn't played a rated game in over three & a half years. Norm played especially well, scoring 3.5 points out of five, and he had one really nice endgame grind that I hope to post later. Nice work from a newbie and a bunch of drop-outs!*

So we scored two team trophies, which was all we could realistically hope for. (Great Britain and Pine Hills were competing for the same trophy.) Paul quipped, "Once again the Clermont Chess Club has demonstrated its dominance of the lower echelons of the USATS!" 

True, but not entirely fair! Unless we were to get the best the club has had through the years (e.g., Mark Ritter Ryan**, Theo Slade, Ray Robson(!)), and maybe recruit a couple of other strong players, we simply don't have the firepower to compete for the top prizes. (Alternately, Connor needs to jump to a much higher plateau.) But this is why they've got sections, and we put up a fight in our class! We do what we can, and that also means putting Garry Day on the team, since Garry's teams always come away with trophies for first place in these events. I doubt anyone has a better lifetime record, percentage-wise. I believe this is now five wins in five tries for Garry.

Good work, gentlemen, and perhaps we can do this again some time!

* I should add that I was returning from almost seven years away from rated chess. I know what it's like, fellas....

** Thanks to Paul for the correction. Sorry to all the Marks involved!

Karpov on Rook Ending "Exploitation Technique"

Karpov on Rook Ending "Exploitation Technique"

While preparing for the USATS (that's "US Amateur Team Championship, South" for our esteemed International readers!) I came across this game in the notes to another game in "Beating the Grunfeld" by GM Anatoly Karpov. While his emphasis was on the opening, it is the rook ending that really stands out to me. This ending is well worth studying (in my opinion) for three reasons:

1) Superior rook activity;
2) Patience in the suppression of counterplay; and
3) Superior and effective kingside pawn play.

For those looking for easy-to-follow themes, I recommend paying attention to Karpov's active king- and if you really want to keep it simple, just follow his g-pawn from start to finish!

Karpov has light notes in the game, but at move 27 he writes "...for twenty moves we have been very close to a draw, but White has nonetheless extracted everything possible from the position; exchanging most of the pieces, he has obtained a superior rook ending. The remainder of the game provides a good illustration of 'exploitation technique' ".

When I originally decided to post this game, I had decided that I was going to add an exclamation marks to 29. g4! and 33. g5!, as I thought it was a very critical idea to the whole ending. Once I found the game in chessbase, I was happy to see that GM Ftacnik had annotated the game, and at moves 29 and 33 he had already added the "!" for me!
