| May-25-09 | | Nikita Smirnov: the famous triangle manouvre! |
 |
| May-25-09 | | geeker: Seems fair for a Monday, even on the hard side in some technical sense because there are a number of candidate moves. But any player who's ever studied the concept of "opposition" in pawn endings should instantly find ...Kf8 (it was the first and only candidate I "analyzed"). |

 | | johnlspouge: Monday (Very Easy):
Tartakower vs Reti, 1925 (75…?) Black to play and draw.
Material: K vs. K+P. Opposition is often a winning advantage in K+P endgames, so Black should deny opposition to the White K. Candidates (75…): Kf8
I defer to <dzechiel>'s explanation, rather than add to the "fundamental Chess-101 stuff" already posted :) |

 | | randomsac: The classic K and P vs K endgame. This is one of the few endgames I am actually comfortable with. Black must retain the opposition so the white king cannot advance. Solution:
75 ...Kf8
76 Ke6...Ke8
77 f7 ...Kf8
and black draws by stalemate or winning the pawn |
|
May-25-09
 | | SuperPatzer77: Black's only move for a draw is 75...Kf8! =.
75...Ke8??? or 75....Kg8??? 76. Ke6 
SuperPatzer77 |
|
| May-25-09 | | WhiteRook48: 75...Kf8. Obvious |
|
May-25-09
| | SuperPatzer77: After 68. Kg5, Tartakower hopes for 68...Ke3?, 69. Kg4! Instead of 68...Ke3?, Reti's only move for a draw is 68...Ke5!, 69. Kg4 Ke6! (not 68...Kf6?, 69. Kxf4 ), 70. Kxf4 Kf6. = SuperPatzer77 |

 | | Peligroso Patzer: < *** this really was too easy even for a Monday.> Maybe so, but I did once swindle half a point in an acute time pressure scramble from a comparable position (I don't believe it was identical; I cannot now remember exactly which file the lone pawn was on, but it does not really matter as long as it was not the a- or h-file, which it wasn't.) when an opponent rated around 1600 played the equivalent of 75. ... Ke8? in the given puzzle position. Many moderately strong tournament players do not adequately study such simple endgames to the point where it becomes automatic to play the king straight back (75. ... Kf8), so a little review of these positions can never hurt. |

| | zenpharaohs: waustad: "If nothing else, the opening is strange. What's the point doing 1.) c3 as white? It makes a little more sense than Andersen's or something like the Grob, but not much. Why take a drawish line like the Caro-Kann and give the opponent an extra move?" According to chessgames.com, this was the 35th meeting between Reti and Tartakower. Although closely matched overall, the story with Tartakower as white is interesting. Here are the scores: 1-0
1-0
1-0
1-0
1-0
1-0
1-0
1/2-1/2
1-0
OK at this point if you are Tartakower, you are liking these results. But then: 0-1
0-1
1/2-1/2
1/2-1/2
1/2-1/2
0-1
0-1
1-0
Yikes! Reti has turned the tables!
And this is where the current game occurs in the Tartakower-Reti sequence. I don't find any mystery in Tartakower taking a cautious opening out of the bag at this point. The rest of the sequence?
1/2-1/2
1-0
1/2-1/2
1-0
Can't argue with that from Tartakower's point of view. |

| | awfulhangover: Chessgames.com cannot be a site for experienced players only, it must be for everybody that has learned the basic chess rules. I think it's very fine if they reminds us about essential knowledge now and then. It's easy to forget such little tricky things in time trouble. |

 | | Phony Benoni: Hey, everybody, don't be so smug about this one. There was a time in your chess life when you would have mangled it. Indeed, I once saw an experienced Class B player lose it in a tournament game. And I do mean experienced--the fellow was old enough that he could have learned it personally from Capablanca's father. Another time, I watched two Class E juniors reach a similar position. The guy with the pawn <really> wanted to win. The other fellow knew the drawing technique, but wasn't familiar with esoteric rules like triple repetition or 50 moves. So, they played over 100 moves from this point--keeping reasonably accurate scores along the way, I must add. The position was on its 13th repetition when the tournament director finally decided enough was enogh and declared the game drawn. |

| | eternaloptimist: 75...Kf8 to get the opposition. It's very easy to solve this if u understand how to get the opposition. |
|
| May-25-09 | | dumbgai: 75...Kf8 of course. However, I have seen many beginners who have never studied endgames play any of the other king moves and lose. |

 | | Calli: Tartakower said 53.gxf4 was an error and he had good chances with 53.Be7!

| May-25-09 | | CHESSTTCAMPS: Those who are bored by a basic endgame position might want to try out a more complex "distant opposition" (or "corresponding squares") puzzle such as the following study by Lasker/Reichelm:

 | | YouRang: Anyone who knows king-and-pawn basics will know about 'opposition' and how black can get it only with 75...Kf8 (so that 76.Ke6 can be met with 76...Ke8 -- grabbing the opposition). But it's a good instructive puzzle for those who aren't familiar with these basics. |

| | YouRang: I wouldn't be surprised if cg.com treats us to a series of puzzles this week featuring king & pawn endgame principles -- of course with ever-increasing levels of complexity. :-) |

 | | playground player: All that work just to get a stalemate! Tsk, tsk... |
|
| May-25-09 | | dumbgai: Good rule of thumb for the defending player in KP vs. K is to move the king straight back when forced to retreat (not diagonally back). |

 | | Sneaky: The people who actually learned the lesson here are probably a little too intimidated to jump into the conversation and be one of the kibitzers, but they are out there for sure. |

 | | benjinathan: I am not too intimidated. This is timely. I know the idea but I blew it in the identical position last night. I was in a bit of time trouble, got flustered about whether there was a different rule when the pawn was on the side file and was trhying to remember whether the rule was stay an odd number of squares away or even. As son as I moved, my kids went " Oh Dad!", head slap, resign. |
|
| May-25-09 | | remolino: In pawn endings, taking the opposition is not always the right answer. So watch out. If you do not know the answer by memory, you better calculate. |
|
| May-25-09 | | pferd: You cannot gain the opposition against the White King because the pawn prevents you from going to e7, hence you go to f8 and now the pawn prevents <White> from gaining the opposition, and when White plays Ke6 then you gain the opposition with Ke8. The key move was 69...Ke6 (not 69...Kf6?? 70.Kxf4 wins) so that after 70.Kxf4 <then> 70...Kf6 gaining the opposition. Basic chess, of course, but a great way to demonstrate to a novice chess player that there must be a LOT to the game, if there is even a right way to play such a simple position. By the way 68...Ke5 is also instructive. A beginner Black might try to exploit the fact that his pawn is more advanced, and play 68...Ke3 after which 69.Kg4 and Black and White are in mutual zugzwang (You can give Kasparov choice of sides, AND let him go first, and win every time!) |

| May-25-09 | | pferd: <remolino: In pawn endings, taking the opposition is not always the right answer. So watch out. If you do not know the answer by memory, you better calculate.> In chess one inviolable rule is that every rule has an exception. They usually end up making beautiful problems or studies. So educate us: give us an example. |
