Jan-18-11  gourav27: Easy puzzle!!
Jan-18-11  mastermind7994: Easy puzzle indeed although what it surprised me was the opening that White chose.
Jan-18-11  mqhelisi: I saw the more Ozone friendly 30.Rxd7 Qxd7 31.Nc5.....from there Bxd5, Nxa6 Qxf7 following depending on response
Jan-18-11  1.e4effort: Just a lot going on here! White is about to lose a Rook, but has checking options. There are several ways to go about the check with the 30th move, but the longer I look at this the more I see a battleground on f6 as white has 5 pieces directed right at it, with another pawn waiting in the wings. Most forcing is 30.Qf6+. Black should capture with his N. Now comes the tricky part - does white retake the square with p, N, or R? Too much for me to think about at work. I'll look and see.
Jan-18-11  Patriot: I've been having thoughts of giving up on this game and today's puzzle further pushes me toward that. A streak of bad games and lousy blitz play... But I guess a lot of players go through that?

Today I missed 30.Qf6+ probably because of a quiescence mistake. I looked at a number of ideas including 30.Rxd7 Qxd7 31.Nc5, but 31...Qa7 pins the knight so that 32.Nxa6 Qxa6 33.Bxd5 cxd5 34.Qxf7+ is no longer possible.

30.Nf6 was my choice. The idea is that it threatens either 31.Nxd7 or 31.Rxd7 or 31.Bxd5 seeing that the rook on a6 is undefended. So 30.Nf6 Nxf6 31.exf6+ wins. Also 30...Bxg2 31.Rxd7 Qxd7 32.Nxd7 Bd5 should give white an advantage. But after seeing the solution it seems that 30.Nf6 fails to 30...Nxe5. Now 31.Bxd5 Qxd6 or 31.Nxd5 Qxd6 and the knight conveniently protects f7.

At least I'm not alone in missing today's puzzle.

Jan-18-11  ECaruthers: I was among the spectators when Suttles played Evans, San Antonio, '72. And I have the tournament book that includes disgusted comments by Evans on some of Suttles' other games. Every year or two I play through a bunch of Suttles' games, but I still can't figure how he gets such good middlegames from his openings.

  patzer2: For today's Tuesday puzzle solution, 30. Qf6+! removes the guard or defender and wins a piece. If 30...Kf8, then it's 31. Qh8#.
Jan-18-11  CHESSTTCAMPS: In this middlegame attacking position, material is even but white has much more active pieces and a strong grip on the semi-open f-file. Black is threatening 30... Nxe5. White must utilize the e-pawn and the hole at f6 before the opportunity disappears.

30.Qf6+!

For some odd reason, I saw this right away, but miscalculated and started looking at other candidates. Only after finding nothing, I came back to it. One better appreciates the economy of the solution after seeing that the alternatives are not effective. Black must drop a piece:

A) 30... Kf8 31.Qh8#

B) 30... Kg8/h6 31.Qxe7

C) 30... Qxf6 31.exf6+ Nxf6 (Kf8 32.Rxd7 is even worse) 32.Rdf6 (or Rff6) leaves white up a piece for a pawn, with c-pawn or f-pawn doomed.

D) 30... Nxf6 31.exf6+ Kf8 (Qxf6 transposes to C) 32.fxe7+ Kxe7 33.Rdf6 wins a piece and the f-pawn after Ng5 or Nc5.

Cute Tuesday puzzle.

  kevin86: White lends his queen to set up a lethal pawn fork and a piece profit.

Jan-18-11  rilkefan: <<patriot>: A streak of bad games and lousy blitz play... But I guess a lot of players go through that?>

To some of us that sounds pretty good... All my chess playing buddies are on the wrong coast.

  Once: <Patriot: But I guess a lot of players go through that?>

Frequently. But I have a theory that chess below GM level is almost certainly doomed to disappointment.

It's the grading, you see. I do well and my grade climbs. This means that I end up playing stronger players, who beat more more often ... and so my grade falls. Then I find myself playing lower graded opponents and ... I do better for a while. So my grading increases. Repeat.

If you find yourself somewhere between the happy upwards climb of youth and the steady downwards dribble of senility and decay, then the plateau of the grading system means that you ought to be winning about as much you lose. Add in a sprinkling of draws, a smattering of disillusionment and a cluster of losses is almost inevitable.

The good news is that it doesn't last and each poor result is a chance to learn, even if it hurts like the devil to lose. Every. Darned. Night.

Stick with it - it does get better.

Jan-18-11  MaczynskiPratten: Qf6+ is not intuitively easy to see like a lot of puzzle solution moves are - it doesn't seem to follow a standard pattern. A Queen sac to regain the Queen with a pawn fork and win a Knight isn't common. Anyone know of any similar examples?
Jan-18-11  Patriot: <Once> Thanks for the encouraging words. I can really use them right now.

<rilkefan> Maybe some of your buddies could play you online? I know...it's not the same thing but at least it is still possible to play them.

Thanks for the comments. I emailed my instructor and he replied with the following words. Maybe this can help other's as well:

"Chess has to be fun - it's a hobby. If it loses its fun you have to ask why; often it is some side effect of the rating system. So ask yourself if there was no rating system, would you still be having the blues? Make sure to do things that are fun - in the long run that will help the most; forcing yourself to do things that are not fun just because you think they may help is counterproductive in the long run (although some things that are not initially fun do eventually turn out to be fun).

And of course all humans have ruts and slumps; getting thru that is a measure of perseverance (see my NN on slumps). And you had a really big run, so it may have been overdue. That's no cause for concern in itself. As Seirawan asked at the Supernationals "Has anyone here lost 10,000 games?" When one raised his hand, he said "You are on the right track!"

So the best encouragements I can give are: 1) You are doing very well in general, 2) All humans have ruts and slumps at most everything, 3) Getting thru them is a measure of perseverance, which is necessary, and 4) Always use the "fun" aspect. Sometimes just a short break is enough, sometimes just a short break from one of your chess activities.

And there is no doubt you will get better at blitz if you manage your time (keep an eye on the clock at all times). Those same tactics you do well at the Tactics server will beat most of the opponents you play :)"

Jan-18-11  wals: Blast, pulled the wrong rein that time.

Rybka 4 x 64

Black error: d 17 : 5 min :
(+1.12):28...Nd7. Best,
1. (0.68): 28...h6 29.Ne4 Nb7 30.Rd4 a4 31.g5 Rh8 32.gxh6+ Rxh6 33.Nf6 Rh8 34.b4 Nd8 35.c3 Ra7 36.Rd6 Bc4

2. (0.83): 28...a4 29.b4 Nd7 30.g5 Ra7 31.Qf6+ Qxf6 32.exf6+ Kg8 33.Bxc6 Nf8 34.Bxb5 Rxc2 35.a3 Ra2 36.Rd3 Bb3 37.Re1 Ne6 38.Rd8+

Black blunder: d 17 : 6 min :
(+3.81):29...Bd5. Best,
1. (1.19): 29...a4 30.Rf2

2. (1.19): 29...Nf8 30.Rf2 a4 31.Nc5

and Black resigned move 34.

Jan-18-11  Alekhine2000: I think that 30. Nf6 still wins for white. It attacks black's d7 knight. Black connot take on g2. 30... Bxg2 31.Rxd7 Qc5+ 32. Rf2 with may maating threats. for example: 32... Bh3 33.Rxf7+ Kh8 (Kxf7 Nd7+ wins the queen) 34. Rxh7 mate. So 30...Nf8 31. Bxd5 wins a piece cause after 31...cxd5 32.Nxd5 Qa7+ 33.Kh1 Rxd6 34. Pxd6 h6 (to avoid mate) 35. Qe5+ kh7 36. Nf6+ Kh8 37. Ne8+ f6 38. Qxf6+ wins the knight no f8
Jan-18-11  WhiteRook48: 30 Qf6+
Jan-18-11  David2009: Suttles vs P Ostojic, 1969 White 30?

Hard for a Tuesday. I spent several minutes before finally finding 30 Qf6+. Capturing the Queen loses a N, not capturing the Q (K moves) is immediately fatal e.g. 30...Kf8? 31 Qh8#. Time to check:

Yes. Crafty End Game Trainer link to the puzzle position:

http://www.chessvideos.tv/endgame-t... Youy are White in this free Internet link, drag and drop the move you want to make. Win this or not as you please: I'm off to bed, goodnight (23.35 over here).

Jan-18-11  Patriot: <Alekhine2000> You made the same mistake I did. 30.Nf6? Nxe5 is slightly winning for black as confirmed by Fritz. It says 31.Rxd5 (only move) cxd5 32.Nxd5 (-1.24).

It's amazing. All it takes is missing one key move from the beginning and you can go from winning to losing. Maybe we'll have better luck tomorrow.

  Phony Benoni: Like so many others, I started off looking at 30.Rxd7 for a good while, and also considered 30.e6. Why is 30.Qxf6+ so hard to see or accept?


click for larger view

Oddly, I think it's because the first thing you think of is that Black can trade queens, not play 30...Nxf6. In puzzle mode trading queens is very rarely right, so the move doesn't make a good first impression

Let's alter the position somewhat:


click for larger view

Now, in puzzle mode, 1.Qf6+ is obvious since there is no queen trade involved.

Which leads to another question. Since being in "puzzle mode" is an artificial way of approaching a position compared to "playing" mode, does solving puzzles really help in practical play? For myself, the answer is clearly yes, since I rely heavily on pattern recognition and intuition when playing. The more patterns I see, the more that become instinctual responses, almost reflexes.

Besides, my style requires that I rely heavily on the sort of miracles you only find in puzzles!

Jan-18-11  BOSTER: <Patriot>
<And there is no doubt you will get better at blitz if you manage your time ( keep an eye on the clock at all times)>. <keep an eye on the clock at all times>-believe me, this is absolutly wrong. Best, who plays blitz, sometimes even don't look at clock,they have feeling.
Jan-18-11  shoaibk: got this one :) Qf6+ wins a Knight. This puzzle isn't "easy" for a tuesday
Jan-18-11  Patriot: <BOSTER> It's true that some play it that way. I use blitz as a way of quickly practicing openings, learning to quickly see threats and basic tactics, and practicing time management.

I have a bad habit of getting into time trouble because I get so involved in the game I often don't realize how much time I'm using up. Believe me...this is good practice for me.

Jan-18-11  pmukerji: How about 30. Nc5. This is interesting because if 30. ...Nxc5 then 31. Bxd5 and exerts pressure on f7. In addition B can't really play cxd5 because black loses his rook. If B plays 30. ...Nxe5 instead then white still plays 31. Bxd5 and 31. ...Qxd6. Now 32. Ne6+. If 32....fxe6 then 33. Qf6+ Kg8
34. Bxe6+ Qxe6
35. Qxe6+
and at this point I think B will also lose a knight leaving black with 2 rooks and white with a queen and a rook. I did this kinda quickly and am not sure if I overlooked something...
Jan-19-11  Oliveira: <pmukerji> 30.♘c5?? ♘xc5 31.♗d5 cxd5 32.♖xa6 ♘a6
