  kevin86: The final fin sets up a fork-and wins queen for rook. White would be up a bishop and pawn.
Nov-19-08  peristilo: This one was easier than yesterday´s! And yet very instructive! I had seen one very similar to this some months ago.

  YouRang: Ack! I gave 29.Qxh8+ line a long look, and I got the whole line except my board vision failed me.

I just didn't see through the clutter that 31.Ra7! was a queen pinning, knight-fork setter upper. :-(

Nov-19-08  zb2cr: Hi <ChessApplet>,

Thanks for your opinion. I enjoy the back-and-forth exchange of opinions and in some cases this contributes to my education.

Nov-19-08  Riverbeast: The Bronx Bomber strikes again!
Nov-19-08  ChessApplet: Hello < zb2cr >!

Anyway, I am also in the process of improving my game. Are you in a chess school or any formal study of chess?

Nov-19-08  skemup: I missed it. I thought about 31. Rea1 or 31. Nxb5
Ra7 was not obvious for me,as for black..

  playground player: That wasn't so blinkin' easy! Finally found it, but never would have found it with a clock ticking away beside me.
Nov-19-08  akapovsky: I was just thinking if we had to rate the daily puzzles by giving it an average elo level how would mondays, tuesdays ect be rated not including the "median easy" type rating but for example an 1400 elo.I thought this would be similar to that of the glicko system of rating.
Nov-19-08  TheaN: Although I'm not very aware of how the glicko system works (very coincidentally, I read something about it on FICS for the first time just now), I think it's not a correct way of judging puzzles. It's the same as how it works on that tactical puzzle site, Chess Tactics Server (www.chess.emrald.net), where I do not believe everything either: some <1300 puzzles leave me literally puzzled for longer than I have, whilst I have some 1600-1700 puzzles in two seconds. On the other hand, that is the same with Easy - Insane ratings... although less specific and thus less biased. I prefer the current setup, as it is usually correct.

  Once: I learned a valuable lesson tonight.

It's been a long day - 13 hours from leaving home to returning back. Sitting with a welcome glass of whisky and the CG daily puzzle as the 10:00 news plays on the television.

The first two moves are obvious in puzzle-land. 29. Qxa8+ Bxa8 30. Rxa8+ Ke7. Now we have control of the back rank and an advanced knight (Kasparov called such a knight "an octopus").

But now what? The a7 square is tempting for a rook, so I toy with 31. Rea1 threatening R1a7. Or 30.e5 to open up the bishop's diagonal. I even spend a tired moment getting way too excited about 30. Re8+ before spotting the doh 30. Nxe8.

And that is when I very nearly called it a day and peeked at the solution. I'm pretty sure that I've got the first two moves, because they are so forcing. The next move must be something like Rea1, right?

Nope, that would be too lazy. So I take another gulp of whisky and look again. Now let's look for a knight check at move 31. I look at 31. Nf5+ but can't get it to work. 31. Nc8+ doesn't work either. The black king just dodges to one side.

Hang on a minute - Nc8+ hits both the black king on e7 and the a7 square that I wanted to plonk a rook on. Can I combine the two ideas?

Then 31. Ra7 Qxa7 32. Nc8+ pops into my befuddled brain. A quick count of material and it looks like we are a piece up.

The moral is twofold. Firstly, don't give up and take the lazy way out - the line that you don't analyse could the the killer refutation that bites you on the bum, or the killer tactic that wins the game outright for you.

Secondly, it often pays to collect scraps of ideas from one line to re-use in another. I only spotted the knight check on c8 because I had already noticed the strength of putting a rook on a7.

Time for another whisky.

Nov-19-08  zb2cr: Hi <ChessApplet>,

In answer to your question:

No, just reading and etc. Too many work and family responsibilities to make a formal commitment such as working with a coach. Plus, money's a bit tight; I have a daughter in college.

My activities on trying to increase my admittedly average strength: Do the puzzles here under simulated game conditions--that is, analyze without moving the pieces, and spend no more than 15 minutes examining the puzzle. I also spend some time every week solving the live blitz-speed puzzles at http://chess.emrald.net. This is part of committing a large number of tactical patterns to mind as recommended by Dennis de la Maza in the book Rapid Chess Improvement. I'm working through a number of endgame studies in a book by Troiztsky; many of those are truly mind-blowing.

Nov-19-08  FizzyY: oooh black was my former chess teacher
Nov-19-08  PinnedPiece: Goal for Wdnesday puzzles: solve in 5 minutes. What I came up with in five minutes was a queen psuedo-sac, because after a series of forced moves (if Q-sac accepted) my Ra1 ends up taking the black queen (from f7). If this doesn't work out, then I lose since my five minutes examination time is now up.

Nov-19-08  garrido: IS EASY THE SOLUTION
BENJAMIN GARRIDO since chile for world
Nov-19-08  PinnedPiece: Ha ha ok my visualizastion sucked.

Maybe if I had played the moves I would have seen Ra7, with follow-up knight fork.

Nov-19-08  Woody Wood Pusher: I saw 29.Qxa8+,Bxa8 30.Rxa8+,Ke7 31.Ra7!,Qxa7 32.Nc8+,Ke8 33.Nxa7

Tougher than a normal Wed. IMO

Nov-19-08  Woody Wood Pusher: < TheaN: 100% (3/3)

Looks like I went a bit too far.... >_> does anyone care about what I have posted beyond the BB variation? Prolly not :P.>>

I liked it. I looked a bit further as well just like you, it is a nice position.

Nov-19-08  apple pi: <oooh black was my former chess teacher> what an interesting surprise! I guess you know how to beat him now:-)
Nov-19-08  yoozum: < Once: I learned a valuable lesson tonight. >

I learned that I might have to sit down to look at these with a glass of whisky more often.

Nov-19-08  stacase: Yoosum,

Last time I checked, alcohol and Chess don't mix.

Nov-19-08  Dr. J: <TheaN> Regarding your BBDBB variation: 33 c6+ and White either queens the pawn or forks the Black rook.
Nov-20-08  yoozum: <stacase: Yoosum,

Last time I checked, alcohol and Chess don't mix.>

They actually mix pretty well for me...up to about 2 drinks ;-)

  Viewer Deluxe: My thanks go to GM Cheparinov who played very similar “unprotected” rook move just three days ago at the Chess Olympiad. Take a look at 30. Rh8+ in this game I Cheparinov vs Pavasovic, 2008

  FSR: Black must have intended 20...Bxc5, then noticed to his horror that 21.e5! wins.
