|May-12-12|| ||Gurn: In the course of the game, at move 32 would not Kf7 instead of Kd5 be a better move for black?|
|May-12-12|| ||srag: A superb performance of The Great Lasker!|
|May-12-12|| ||David2009: Lasker vs Tarrasch, 1914 White 40?|
Black is threatening to queen by force in six moves using Pawns alone. White needs to stop this. This suggests 40.h4 gaining a tempo to bring
the WK into the 'queening square'. The game could continue 40.h4 Kg4 forced. Now 41.Kf6 c4 42.bxc4 bxc4 43.Ke5 c3 44.bxc3 a4 wins for Black so White gains a second tempo with 41. Kg6! forcing 41...Kxh4. Now 42.Kf5 forces at least a draw for White. One variation: 42.Kf5 c4 43.bxc4 bxc4 44.Ke4 c3 45.bxc3 a4 46.Kd3 and White wins. Time to

I got most of it, but did not analyse Tarrasch's save Kg3 etc. Worthwhile problem.
Here's the problem set up on Crafty End Game Trainer:
http://www.chessvideos.tv/endgame-t... The robot finds an interesting drawing line for Black: 41.Kg6 Kxh4 42.Kf5 c4 43.bxc4 bxc4 44.Ke4 c3 45.bxc3 (so far as per my analysis) and now not 45...a4? Kd3 1-0 but 45...Kg4! (...Kg5 also works) draw - both Pawns come off. Here's a second link to confirm the win after 45...a4? in this variation: http://www.chessvideos.tv/endgame-t...
It is worth visiting the Free Chess Server (http://www.freechess.org) and typing the command 'tell endgamebot play KPkp' or 'tell endgamebot play KPPkpp' to generate some excellent and trappy K&P endings. <endgamebot> uses a tablebase to play six-man endings: type 'tell endgamebot help' for instructions - thanks <Ludens>!
|May-12-12|| ||mistreaver: Ahh saturday, the end of the week is coming, chess tournament today, Anand and Gelfand
are playing. Wonderful :)
So let's try to be quick with this one and then go enjoy (it can't end up good).
This is Lasker vs Tarrasch, and i think this one is from San Sebastian tournament 1911.
I have definetly seen this in Kasparov's book, and i remember that white gains a draw here.
So let's see
40 h4 Kg4 (forced)
Now white has to decide whether to advance or to maintain status quo.
I like dragging the black king away:
41 h5 Kxh5
42 Kf6 and now if :
a)46... Kg4 47 Ke5 Kf3 48 Kd5 Ke3 49 Kxc5 Kd3 50 Kxb5 Kc2 51 Kxa5 Kxb3 is a draw
b)46... a4 47 bxa4 bxa4 48 Ke5 c4 49 Kd4 and black is even in danger of losing.
It has to go something like that, time to check.
Argh, i missed the key move, and i know Kasparov gave it 2 exclamation marks. Serves my right for being overconfident. Zero for today.
|May-12-12|| ||Marmot PFL: To solve this for white is fairly easy, he is playing almost forced moves and hoping to draw. 40 h4 is the only active move, and since h5 is threatened black has only Kg4, then 41 Kg6 renews the h5 threat, so Kxh5, 42 Kf5 Kg3 and the ending is drawn. Since this clearly draws there is no need to delve into 41 Kf6 c4 42 bc bc 43 Ke5 c3 44 bc a4 45 Kd4 a3 when the pawn on c3 blocks its own king.|
|May-12-12|| ||LoveThatJoker: Excellent! A Lasker puzzle!
<40. h4 Kg4>
(40...a4 41. bxa4 and now White is doing fine with with either a or h pawn)
<41. Kg6 Kxh4>
(White threatened 42. h5 with the promotion of the h-pawn in hand)
<42. Kf5> and now, at the very least, White cannot lose. For example,
42...a4 43. bxa4 bxa4 44. Ke4 c4 45. Kd4 and White at least draws.
42...c4 43. bxc4 b4 (43...bxc4 44. Ke4 c3 45. bxc3 a4 46. Kd3 and now, if there are any, White has all the winning chances) 44. Ke4 a4 45. Kd3 and again White at least holds.
|May-12-12|| ||LoveThatJoker: Yes! Full point for today! And I've guaranteed my pass for the week with a 5.60 out of 6 thus far!|
|May-12-12|| ||kevin86: Outside passed pawn! Black must take the h-pawn before it becomes a threat. Then white gobbles up the black pawns,but not before black can eat white's as well.|
|May-12-12|| ||dumbgai: This endgame is very instructive. Pawn endgames can be very tricky even when they look simple.|
|May-12-12|| ||mikmik777: White to play: 40. ?
Lasker vs Tarrasch
Equal material but, Black has superior pawn formation and a more centralized king.
In this position, White can play for a draw by giving away his h-pawn. Black can't take the c-pawn otherwise it will be stalemate.
52.Ka8 Qxc7 stalemate
At first I tried to look for a win for White but found these variations, all in Black's favor.
(41.Ke7 c3 42.bxc3 a4 43.bxa4 bxa4 44.c4 a3 45.c5 a2 46.c6 a1[Q] 47.c7 Qe5+ )
(41.bxc4 bxc4 42.h4 c3 43.bxc3 a4 44.c4 a3 45.c5 a2 46.c6 a1[Q] 47.c7 Qa8 )
Let's see happened.
|May-12-12|| ||RookFile: If you showed this to somebody today and told him Kramnik had played black, he might believe you. It looks like him.|

|May-12-12|| ||playground player: White's position was not as bad as it looked. "Draw" immediately occurs to the observer.|
|May-12-12|| ||mikmik777: Totally missed the line.. Very nice input <FSR>..:)|
|May-12-12|| ||patzer2: I would have played 40. h4! in blitz, but perhaps that's because I've played quite a few pawn endings out against the computer and in endgame book problems and this one just seemed instinctive.|
Decoy the White King and using the tempo gained to chase down the Black pawns seemed to me to be the strategy for securing the draw. End games are often like that. You've got to give up something to gain something. In this case, a pawn for a critical tempo.
P.S.: Quickest I've ever found a Saturday solution.
|May-12-12|| ||James D Flynn: 40.h4 Kg4 41.Kg6 (The critical move, see below for Kf6) Kxh4 42.Kf5 c4 43.bxc4 bxc4 44.Ke4 c3 45.bxc3 a4 46.Kd3 a3 47.Kc2 Kg4 48.Kb2 Kf4 49.Ka3 Ke4 50.Kxa4 Kd3 51.Kb4 and the White K will escort the c pawn to queen.
41.Kf6 would be a mistake because c4 42.bxc4 bxc4 43.Ke5 c3 44.bxc3 a4 and the Black K does not arrive time o stop the White a pawn from queening. All attempts y black to advance th h pawn will be met by Kxh4 if Kg6 or Kxh5 is h5 and the Black h pawn will queen.
Tarrasch may have been playing for the position because the fact that his pawn formation on the Q side enables him to create a passed pawn where the White K is far away Looks like a win. The resource Kg6 is difficult to see in advance,|
|May-12-12|| ||BOSTER: <Jim> <White's king has to stay on the b1-g7 diagonal>.|
Does this diagonal exist?
|May-12-12|| ||Abdel Irada: White superficially appears to be in a bad way: His passed h-pawn can't get through; his queenside pawns are crippled and outnumbered, and his king is out of play. But the possession of pawns on both wings is a weapon that, if wielded featly, can wrest victory as follows: 40. h4, ♔g4 (40. ...c4?; 41. h5, and white's h-pawn is unstoppable); 41. ♔g6!, ♔xh4 (compulsory because white has renewed the threat of 42. h5, but now white has the opposition and will get his king to the queenside first); 42. ♔f5, c4 (I see nothing stronger for black); 43. ♔e4!, cxb3; 44. ♔d4, a4; 45. ♔c3. White wins because his king is now close enough to halt and pick off the black pawns while his own pawn on b2 makes its way to the eighth rank.|
An interesting sidelight: This is one of those cases where after ...c4 (or ...a4), white need not capture, since black's capture on b3 does not gain him any time. More important is to bring the king to the critical c3 square with all possible dispatch.
|May-12-12|| ||Abdel Irada: Ah, the penalty for hubris: I completely overlooked Tarrasch's 42. ...♔g3, after which black's king gets back in time to save the day. Oh, well. I guess if Lasker had to settle for a half-point, I'll have to settle for half credit.|
|May-12-12|| ||Jimfromprovidence: <BOSTER> <Jim> <White's king has to stay on the b1-g7 diagonal Does this diagonal exist?> |
Yes it does, in another dimension on a subatomic level. Of course I meant b1-h7.
Thanks for pointing out my error.

The above position is a forced win for black, with black to move. Can you find the correct continuation?
See link to solution below. (In Dutch).
|May-12-12|| ||Richard Taylor: This position is in quite a few end games books so I knew the solution as soon as I saw it! Pays to do the study!|
There are lot of these types of position when the geometrical motifs make the "obvious" moves deceptive.
It is instructive as they say.
|May-12-12|| ||Patriot: Material is even. Black has a 3:2 majority on the queenside and white has a passer on h2. Black threatens 40...a4 41.bxa4 bxa4 and 42...c4, 43...c3, 44...a3 etc. Black can continue with this plan after 40.Kf7, so I think 40.h4 is the only try.|
40.h4 Kg4 41.Kf6 Kxh4 42.Ke5 should draw.
|May-12-12|| ||Patriot: Ah, I see! Nice problem! 41.Kg6 is the only way to draw.|
|May-12-12|| ||Infohunter: <Jimfromprovidence> Nice exercise, thanks. Just out of curiosity, how did you find that site?|
|May-13-12|| ||Jimfromprovidence: <Infohunter> <Nice exercise, thanks. Just out of curiosity, how did you find that site?>|
The position is in Nunn's Chess Endings Volume 1. I could not find the game in CG's database, so I simply Googled it, looking for a link with some analysis. That site came up.
