Mar-03-09   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...

  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!

  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...."

  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.Rf3 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.

Mar-03-09   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.

  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.

  kevin86: I saw the key move in a part of a second. The queen sac is so lethal that the mate can actually come a move later than expected. With the rook at f3-you have a Monday puzzle.

After 27 Qxg6!! hxg6 28 Rf3 and the mate is inescapable. The queen or rook can kamikaze itself to delay the mate,but cannot stop it.

  ZUGZWANG67: Hi <fyad reject>

Just keep trying!

QUIET MOVES (as one calls 27.Rf3 here) are among the most difficult to find. That is because such a move does not attack anything immediatly but instead introduces a delayed threat, here 28.Rh3. The main difficulty related with a QUIET MOVE is that although it seems to be a kind of 'hoping-the-opponent-don' t-see-the-trick' move, it is in fact flawless, as Black does not have any way of defending against the delayed threat, nor has he any sort of counter-attack to disturb.

By the way, here is an interesting link for practicing. You will find there hundreds of easy-to-solve puzzles, classified from 1 to 4 move solution.

This also apply to <nanok> as well.

Peace!

  gawain: Yes, Q sac and rook lift. There is nothing Black can do about it. His heavy pieces are helpless. Very pleasing.
Mar-03-09   TheChessGuy: Black is so tied up that White can sac the queen and play Rf3, and the mate is still forced.
Mar-03-09   Operation Mindcrime: Easy and nice theme here. Qxg6!! opens the h-file, after which the quiet Rf3! leaves Black helpless against Rh3#. All he can do to postpone mate is a few spite moves...
Mar-03-09   laskereshevsky: A classical tema.... very easy if you already know this schematic mate,..

but enough easy to catch even if you dont know it....

Mar-03-09   Riverbeast: Qxg6 MUNCH!!
Mar-03-09   YoungEd: The YoungEd juggernaut cannot be stopped! Got this one in a flash! :)
Mar-03-09   SamAtoms1980: Monday/Tuesday Modus Operandi.

1) First choice, look at the most violent (usually Queen) sac available on the board.

2) Dismiss the enemy position as hopeless if the sacrifice is rejected, if it can be.

3) After sacrifice is accepted, continue with obvious follow-up.

4) Check to verify that the enemy cannot stop the mate threat, or only by giving up their own Queen and more.

5) Score one point.

Mar-03-09   WhiteRook48: I usually look at the sac of the most valuable piece currently on the board

  Raf: Bishop controlling g8 is what helped me to solve this puzzle. What left to find was a simple check.

<26.?>

Material: /+\ B/N

Candidates: <[Qxg6]>

-ML-
The 'puzzle' is relatively easy because the position presented only has one 'puzzle move'. However, finding such a move in a game is something completely different, as compared to the Monday puzzle.

<26.Qxg6!!> is a relatively passive Queen sacrifice that leads to a completely won game for White. Accepting, although the continuation is a passive move from White, leads to mate.

/A\
<26....hxg6 27.Rf3> and Black has no defense to mate along the h-file.

<27....Re6 28.Bxe6 Qf7 <(28....Qe7 29.Rh3† Qh4 30.Rxh4‡ 1-0)> 29.Bxf7 Rg8 30.Rh3‡ 1-0>

/B\
However, Black doesn't have that many good moves to counter. Black has lost a piece and the threat is still there. After Qe7 or h6:

<26....Qe7 27.Qxf5 > and Black is lost.
