|Apr-07-11|| ||OhioChessFan: I didn't realize what a minority it is to enjoy end games. That's where the logic of chess seems so overwhelming. Openings? Zzzzzzzzzzzzzzz. Middle games? Too many possibilities and I get lost in the variations. End games? That's where I love chess. As for the puzzle, very simple and I took about 3 seconds to come up with 42. Be8+ Kxe8 43. Kxe6 Be7 44. Bg5.|
|Apr-07-11|| ||morfishine: 42.Be8+ Kxe8 43.Kxe6 Be7 and white should win this with little difficulty as black is defending on the back ranks and will have to surrender the opposition and/or move the bishop allowing the white king-in|
|Apr-07-11|| ||zb2cr: 42. Be8+ is easy to see. The real key to the puzzle is what you saw on White's 44th. After 43. ... Be7, both 44 Bg5 and 44. c4 are powerful moves--but the game move seems a little stronger somehow.|
|Apr-07-11|| ||gmalino: Contrary to <OhioChessFan> I see more and more how much I like complicated positions in middle games and how weak I am in this logically structured endgames.
So it's exactly this field I have to explore deeply to improve my capacities.|
Any suggestions for literature? Or even better:websites?
PS: I didn't see anything today, not even Bxe8+.
|Apr-07-11|| ||chessaddict25: got it at first glance.Usual endgame motif.|
|Apr-07-11|| ||Patriot: I spent 3 minutes on this, seeing that 42.Be8+ Kxe8 (42...Ke7 43.Bxg6 ) 43.Kxe6 Bd8 (43...Bg7 44.Bf4 ) 44.Bg5 Bxg5 45.hxg5 and there's no stopping 46.Kf6 and 47.Kxg6.|
After looking at the problem, I thought "44.c4?" It looks a little strange especially since the direct 44.Bg5 is winning. But white's position is just that good.
<gmalino> Personally I like Silman's endgame book that came out 2 (?) year's ago. Everyone that I've talked to thinks this book is excellent (including myself). He breaks the book down into USCF ratings and what you should know at that level. If only I had studied the technique of winning K&P vs. K&Q where the pawn is a protected rook-pawn, one step away from promotion. With 15 seconds remaining I drew against a 1950 when it was winning. This would have been an extra 50 bucks in my pocket! :-)
<PS: I didn't see anything today, not even Bxe8+.> According to my instructor, this is one of the first candidates you should see! At first I didn't see this check and looked at Bxb6, Kc6, and the "quiet" Bc4. After seeing the check I quickly started calculating that.

If you scroll down, he has them grouped by subject area.
|Apr-07-11|| ||LIFE Master AJ: Got it ... 42.Be8+. Places Black in virtual zugzwang ... in just a few moves, its not surprising that Black did not care to continue. |

I would start with "Pandolfini's Endgame Course." Then get a good (small) book on R+P endgames. [Practical Rook Endings," by Mednis, Minev has a similar title.] "200 Brilliant Endgames," by Chernev is a good read ... and you can get it (used) on the Intrenet ... usually for only a dollar or two. (Check EBay.)
I have many resources on the Internet. This page, http://www.ajschess.com/lifemastera..., has several pages attached to it. ("Endgames, Lessons and Challenges." Page #1 and #2.) I have my own endgame school, (http://www.angelfire.com/games4/lif...); and many of my sites have deeply annotated games on them. (See the intro to my forum for more details.)
Sorry to barge in like that ...
Also, coming here is a great idea ... look for a game collection (here) that empasizes the endings ...
|Apr-07-11|| ||LIFE Master AJ: ANY book by Chernev usually has games that have endings - and they are usually explained in a nice, non-technical manner. |
Chernev is one of my favorite writers, I probably learned more from him than anyone else.
|Apr-07-11|| ||paulalbert: AJ I agree with your comments on Chernev. I am rereading the Capablanca endgame book right now. Although the focus is on the endgames, I like that he includes the entire game with comments rather than just starting from s critical position in the endgame phase. This book certainly highlights Capablanca's genius. I wish that I had had knowledge of Chernev's books when I was a boy. I would have become a far stronger and more successful player.|
|Apr-07-11|| ||David2009: Julio Bolbochan vs J Martinez, 1946 White 42?|
White has three tempting alternatives: 42.Kc6, 42.Bd7 and 42. Bxb6!?
Analyse 42.Bd7 first:
(A) 42...Nb7 43 Bf4 seeing 43...c5 44 Kc6 Bd1 45 Bc7 etc; if 43...other 44 Bxc7;
(B) 42...Nf8 43 Kc6 Be5 44 Bf4 Bxf4 45 gxf4 and if c5 White can choose between 46 Kd6 followed by Bb5 etc
(which should win but is slow) and the more forceful 46 Kxb6!? Nxe7+ 47 Kxa5 Ke6 48 Kb5 Kd5 49 b4 cxb4 50 cxb4 with an interesting ending.
Line (B) is not completely clear-cut so examine 42.Kc6. The threat is 43 Bc4, 44 Bxe6 and 45 Kxc7. Possible defences:
(A) 42...Bd4 43 f4 Bf6 (if Bd6 44 Bxb6) 44 Bc4 Ke7 (if Bd8 45 Kd7! wins the Ne6) 45 Bxe6 Kxe6 46 Kxc7 etc;
(B) 42...Bd8 43 Bc4 Ke7 44 Bxe6 Kxe6 45 Bf4 wins the Pc7 and then the Pb6 etc;
(C) 42...Ke7 43 Bc4 and wins the Pc7. These lines seems more clearcut than 42.Bd7, so I'll choose 42 Kc6 etc.
There is one more try: 42 Bxb6 cxb6 43 Kc6 and if 43...Bd8? 44 Kd7 and the threat Bc4 regains the piece. Instead Black can try 43..Nc5:
44 Kxb6 Ne4 45 Kxa5 Nxf2 46 Kb6 Ne4 47 a5 Nxc3 with good drawing chances. This is less clear-cut IMO that 42.Kc6
Time to check:
Black chose a fourth try: 42 Be8+. I had seen it but saw only 42...Ke7 not spotting 43.Bxg6 winning the King side. Chess blindness!

Here's a Crafty End Game Trainer Internet link http://www.chessvideos.tv/endgame-t...
to the puzzle position as above. You are White: drag and drop the move you want to make.
Well, the EGT comprehensivvely refutes two of my three tries. No real surprise that 42.Bxb6 fails to work (42 Bxb6 cxb6 43 Kc6 Bd7!! with a winning counter-attack on White's King side Pawns which fall like ripe fruit), but against my first choice 42.Kc6? Crafty plays the energetic (and thematic) 42...f4!! which turns the tables. Much better is 42.Bd7 forestalling ...f4! and which wins after 42.Bd7 Nc5 43.Bxc5 bxc5 44.f4 Be7 45.Kc6 Bd6 46.Kb5 c4 47 Kxc4! (but not 47.Kxa5 when Black's B re-enters the game with significant drawing chances). Best of all is the game line Be8+! winning quickly.
|Apr-07-11|| ||LIFE Master AJ: <paulalbert> I assume you are referring to "Capablanca's Best Chess Endings" by Irving Chernev. (I have a copy of the original hard-back book - signed by the writer himself ... it was a gift from someone who like my websites. I also have several paperback copies - that I used to study these games with my students.) |
John Laning (one of my chess students here in Pensacola) and I studied one game very Saturday. It took us a year or two ... but we eventually worked our way all the way through this book.
I LOVE that book! Of course, Capa was a genius, you should never tire of seeing his games. (I certainly don't.) And of course, Chernev was a great annotator, he did it for "the common man" not necessarily to impress other chess masters.
Thanks for the post - I apolgize if I rambled on too much.
|Apr-07-11|| ||LIFE Master AJ: <David2009> I had no trouble winning the endgame. |
This may not seem worthy of a post, but sometimes it is hard (impossible!?) to overcome the computer's defense.
|Apr-07-11|| ||kevin86: Quite easy-white's move was pretty obvious so that he can enter deeply into the opponent's position and bully the king.|
|Apr-07-11|| ||Marmot PFL: <AJ I agree with your comments on Chernev. I am rereading the Capablanca endgame book right now.

One of my favorite's too. As Chernev pointed out, many books focus on the opening and midgame then break off and say the "rest is technique" or some such remark. This book is detailed enough to understand the endings without swamping the reader with variations.
|Apr-07-11|| ||MaxxLange: Add me to the 44 Bg5 group.... I guess 44 c4 is a nice Zugzwang forcing move, but I did not find it. |
If the Knight on e6 had been a Rook, everyone would have seen the first move at once, because it would win material. Instead, it forces a trade into a winning ending.
|Apr-07-11|| ||cyclon: 42.Be8+ Kxe8 43.Kxe6 and now f.e. -Bd8 44.Bg5, or 43.-Bg7 44.Bd4 win is in horizon.|
|Apr-07-11|| ||cyclon: After 43.-Be7 also 44.Bf4 seems plausible.|
|Apr-07-11|| ||morfishine: <OhioChessFan> Good to hear from you and glad you got it. Sure wish you were on team white: we need the music! Good luck :) Morf|
|Apr-07-11|| ||OhioChessFan: Now I am inspired to write a parody about The Evil Minions of Team White.|
|Apr-07-11|| ||YouRang: Not too hard: In the endgame a lot depends on who has the most mobility and better king position.|
White achieves a much stronger position in this regard with the deflection 42.Be8+!, forcing <42...Kxe8 43.Kxe6> (worse is 42...Ke7 43.Bxg6).
But now the black king is pushed to the wall and his bishop needs to be retracted.
Meanwhile, the white king enjoys having edible black pawns on both sides, so if black retracts one way, white can attack the other way.
43...Be7 44.Bg5 leads to a winning B exchange, or the bishop moves again allowing 44.Kf6 to eat kingside pawns.
43...Bg7 44.Bf4 attacking the queenside pawns, with either 44...Kf8 45.Kf7 , or 44...c6 45.Bc7 .
|Apr-07-11|| ||WhiteRook48: i got it, saying 42 Be8+ Kxe8 43 Kxe6 and white can storm the endgame as he pleases|
|Apr-07-11|| ||thegoodanarchist: I thought Bolbochan was much younger. I have much to learn about chess history.|
|Apr-07-11|| ||CHESSTTCAMPS: I'm sure that earlier kibitzers have noted that white has at least two distinctive advantages in this ending, the bishop pair and the more advanced king position. Add to this the fact that the hole on c6 provides easy access to the queenside pawns for the WK and it adds up to a won position, even though a conventional material count might evaluate the position as "about even." However, jumping in with 42.Kc6? immediately would be ill-advised in view of 42... f4! (consider active defenses first!) 43.Bxf4 (gxf4 Bxh4) Nxf4 44.gxf4 Bxh4 and black has the initiative in a likely drawn position. This suggests that the active knight should be eliminated to facilitate the entry of the WK on either side:|
42.Be8+! is thematic (pulling the defending king to the edge) and forcing. Even though there are many white pawns on dark squares, the black bishop has no access to create counterplay:
A) 42... Kxe8 43.Kxe6 Be7 44.Bf4 Bc5 (Kd8 45.Bxc7+ Kxc7 46.Kxe7 wins) 45.f3 Kd8 46.Kf6 wins.
A.1) 43... Bg7/h8 44.Bf4 Kd8 (c6 45.Kd6) 45.Kf7 wins.
A.2) 43... Bd8 44.Bg5! forces a won K&P ending (g6 falls).
A.3) 44... c6 45.Bc7 b5 46.ab cb 47.Bxa5 is comfortably won.
B) 42... Ke7 43.Bxg6 f4 44.gf (Bxf4? Nxf4 with opposite-colored bishops) Bxh4 45.Bxh5 and the f-pawns supported by the bishop pair should win handily.
Time for review...
|Apr-07-11|| ||DarthStapler: I got the first two moves|
|Apr-07-11|| ||stst: Be8+ is the direct line, if KxB, WKxN and WK intrudes the camp;
if Bk Ke7, Be8xP and Bk also collapsing.
Other Bk K moves losses material.
A less direct and quiet line would be Bd7, targeting the N. If N moves, then c4; if not BxN gains material.
