| Mar-03-09 | | MaxxLange: the other essential thing to check for here: can the Bishop's diagonal b3 to g8 be blocked after the rook lift? no, not effectively: ...Re6 or ....Qf7 and the Bishop just takes |
 |
| Mar-03-09 | | andrewleef1: Found it easily. |
|
| Mar-03-09 | | Samagonka: How about white Queen captures black knight to pave way for white rook to mate black king in the h-file? I hope I haven't embarrassed myself by thinking too loud. Let me check. |
|
| Mar-03-09 | | rgr459: I thought it was customary to play to mate back in those days. Very easy puzzle, even for me. |
|
| Mar-03-09 | | Frankly: This was definitely much easier than yesterday. But who would, in an important game, not have spent at least 10 minutes just making sure there was no escape from Rf3 before throwing away the Queen? |
|
| Mar-03-09 | | JonathanJ: my first thought was: let's look if there's a queen sac, so it didn't take me long |

| Mar-03-09 | | Jim Bartle: A pretty good player once got caught in a similar trap: Karpov vs Taimanov, 1977. |
|
| Mar-03-09 | | CHESSTTCAMPS: After 26. xg6! hxg6 27. f3 black, with the king entombed by his own pawns and the monster bishop at b3, can delay but not stop mate after 28 h3. This attacking theme pops up every so often, sometimes in endgames.Time to see if black resigned. In the era when Kolisch played, it was more sporting to play until checkmate. |

| Mar-03-09 | | zanshin: <Jim Bartle: A pretty good player once got caught in a similar trap: Karpov vs Taimanov, 1977.> Interesting game <Jim>. You don't often see Karpov make two blunders in a row. The game was essentially even before White's move 37. |
|
| Mar-03-09 | | CHESSTTCAMPS: So Loyd did resign. For those who may not know, Sam Loyd was a very famous chess composer and puzzle author. Check out the Wikipedia entry. |

 | | johnlspouge: Tuesday (Easy):
Kolisch vs Loyd, 1867 (26.?) White to play and win.
Material: B for N. The Black Kh8 is stalemated. White is looking for a check, probably along the h-file to produce a Greco’s mate (http://www.markalowery.net/Chess/Ch...). Candidates (26.): Qxg6
26.Qxg6 hxg6 [else, drop a N]
27.Rf3
Black has no defense against Rf3-h3#. |
|
| Mar-03-09 | | geeker: Yes, Q sac followed by Rook lift. Very clear illustration of the theme! |
|
| Mar-03-09 | | YetAnotherAmateur: <nanok> Welcome, and don't worry about your playing level. Just keep trying the puzzles and learning from the really brilliant players that hang out here (i.e. not me). And for today's puzzle the queen sac was about the move white really had. I looked at e6 as well, but there just wasn't any good followup to that. |

 | | Patriot: As <johnlspouge> pointed out, the black king is stalemated. That suggests 26.Qxg6, opening the h-file for a rook. 26...hxg6 (or lose a piece). It so happens a rook can get there in two moves (Rf3-Rh3#). The next step is to look for any possible counterplay black may have or any way of stopping the mate threat--black has nothing. I couldn't think of the mate pattern, but thanks to John for pointing out that it's a "Greco's mate". But at least I recognized the pattern... |
|
| Mar-03-09 | | ZUGZWANG67: Material is even and the BK is boxed in.
26.Qxg6 wins a piece, as 26. ...hxg6 27.Rf3 sees Black without defensive ressource against mate. I was about to post a sophisticated and philosophic essay on such a combination, but I decided it would be a little too 'overwrited' :0)
Peace!

| Mar-03-09 | | zenpharaohs: This took me a long time. Last night, Qxg6 was obvious, and I never really thought about any other move. I figured Qxg6, hxg6, Rf3, etc. So Black will not play ... hxg6. So I looked for ways to force the mate. But there really is nothing other than Qxg6. I would have played Qxg6 OTB, but it was getting annoyed at not "seeing how it works". This morning when I got up I looked again, and still, Qxg6 was screaming at me. Then I realized, "if Black doesn't play hxg6, White gets Knight and pawn for free...." |

| Mar-03-09 | | ZUGZWANG67: Hi <nanok>
Welcome to CG.
When rated 1000, I think that one should concentrate on studying tactic and playing often. It doesn' t make sense to learn opening variations by heart, nor to go deep in endgame study. For opening theory, just try to follow what chess players call 'the 3 golden rules', i.e. control the center; develop your pieces; hide the K. For endgame, get familiar at mating with K+Q vs K, K+R vs K, Q(R)+R vs K, and maybe K+B+B vs K. Get acquainted to what is insufficient to mate and some K+P vs K endgame. Learn to recognize tactic patterns like:
THE BASIC MATES;
DOUBLE ATTACKS;
PINS; THE ABSOLUTE & RELATIVE ONES
SKEWERS;
DISCOVERED CHECKS/ATTACKS;
INTERFERENCE;
CLEARING THE PATH (for someone' s piece)
Practice at solving puzzles, say, 1/2 to an hour a day. There are plenty of excellent training books available. Here' s one concentrating on mate patterns: CHESS, by Laszlo Polgar. There' s 5334 problems in that book ! Peace! |

 | | cu8sfan: Day two of my <quest to finally solve seven in a row>. Today it took me a little longer to realize that I would have enough time to bring the rook into play. 26...hxg7 27.f3 and mate follows. Two down, five to go! |
|
| Mar-03-09 | | fyad reject: i dont know how the solution to this puzzle would ever have occurred to me the rook just seems impossibly far away |
|
| Mar-03-09 | | zb2cr: Quite easy to see, if you are familiar with the Rook lift to the third rank. In fact the only reason why this took me longer than 2 seconds was that I considered whether I needed to lift the Rook to the third rank with 26. Rf3 first. I quickly concluded I didn't. As <dzechiel> points out, Black loses a piece. If he plays 27. ... hxg6?, then 28. Rf3 puts his in a position where his only tries to block the a2-g8 diagonal are useless. <RandomVisitor> points out that this is the case due to the Black Rook being on e8. |

| | Patriot: <fyad reject: i dont know how the solution to this puzzle would ever have occurred to me the rook just seems impossibly far away> There were several things that lead me to the solution quickly: 1) The "Greco's mate" pattern is something I "know"; 2) I tend to look at forcing moves (i.e. checks, captures, and threats); 3)The black king cannot move. There are no "checks", so I entertained the idea of "capturing" the knight on g6 with the queen. After hxg6, Rf3 becomes a serious "threat". In this case I used #2 above to calculate to see what happens. The only thing to make sure of is that Rh3# cannot be refuted since white has already invested a queen for knight. |
|
Mar-03-09
 | | YouRang: As soon as I saw that my bishop sealed off g8 for black's king, I considered 26.Qxg6 with black unable to recapture due to 27.Rf3 & 28.Rh3#. I think black must play 26...h6, and he's down a knight with white retaining the initiative. |
