Sep-22-05  paul dorion: <ckr>
25 Qb2 Nc3
26 Qxc3 Qe7
27 Rb8 looks crushing for white
Sep-22-05  zb2cr: Got it, although I initially thought that 25. Qb3 was the move. Then I saw that 25. Qb2 was more forcing.
Sep-22-05  dhotts: It appears to me that Black lost a chance to win the initiative with 14...ed! 15.Nxd4 then either Ng4 or Ne5, both strong moves. What's your opinion?

  benveniste: <paul dorion>, after 26 ♘c3, I see white's best line as:

26. ... ♘c3
27. {Q]xc3 ♕e7
28. ♕d2 c5 (Good as any for black).
29. ♖e7.

Black can squirm a bit, but loss of one of black's minor pieces is inevitable.

Sep-22-05  ckr: <Paul dorion>
27.Rb8, it does look bad and so does 27.Qf3. Black is lost but perhaps, it is that the played line was so clear I didn't think black would walk into it, so I assumed that he would play something else. The position contains more ways to slit your throut than I had seen.

  YouRang: Got it. Since the black queen is guarding the black knight on e8 -- and more importantly, against back-rank mate, the 25. Qb2 deflection of the queen and double attack on the bishop was easy to find.

From there it was just a matter of figuring black's best defense (I considered either 25...Qe7 or 25...f6) which both lead to winning attack by white.

Sep-22-05  EmperorAtahualpa: A nice puzzle! I didn't see it...I was thinking of Bxe7 or Qb3.

By the way, I believe Black should have moved 21...c5 instead of 21...Rxe5.

Sep-22-05  klausewitz: Missed it. Thinking in Bxf7 and Rxe8... Well done...
Premium Chessgames Member
  YouRang: I'm surprised that black took 25...Qxd8, since it loses so fast. How about 25...Qf8. It's bad, but not AS bad.

The follow-up might be: 26. Qxc6 (threatening Rxe8 and Qxe4) 26...Nf6 (holding things together).

Of course, white can now take Black's a6 pawn and start advancing his 'a' pawn, but black could perhaps put up some fight.

Premium Chessgames Member
  YouRang: Forget my last post. I just noticed the flaw in 25...Qf8. Then 26. Qxf7+ Qxf7 27. Rxe8# (black queen is pinned).

  kevin86: I saw ♕b2 but missed the followup-instead I went for the pedestrian ♗xf7+ followed by ♖d7+ winning a pawn. In other words,I went for the walk,rather than the home run.
Sep-22-05  JoeWms: <SamuelS> <Sometimes I miss the most obvious moves. I'll have to do more board visualization exercises.> Are these formal exercises? Or your own thing?
Sep-22-05  paul dorion: <dhotts>
15 Nxd4 Ne5
16 Nf5 looks a lot like the game but with a dangerous R vs Q line-up on the d file

The same thing happens after
16 h3 followed by Nf5

Sep-22-05  ckr: The author of <Chess visualization> also has a web site with training exercises.

Sep-22-05  aginis: <JoeWms> i thought these were visual exercises. I don't mean to be snide but doing these puzzles by moving pieces around is kinda pointless. How are you gonna spot it OTB if you can't do it without pressure and no time control in situation where you are told there is a combo? Not to mention that most puzzles on chessgames aren't exactly grandmaster level. Occasionally a puzzle at the end of the week needs some in depth analysis, but more often than not the difficulty of a sunday puzzle lies in catching the correct theme and order of play - not lengthy or exact calculation.
Sep-22-05  artemis: <aginis> These excercises are to be solved however one can do them. This one was easy for me to see over the board, but I have done thousands of puzzles, ranging from two movers to ten movers and beyond. Every player needs to be able to evaluate their own ability and judge from their if they should be able to touch the pieces. I used to need a board to do ones like this, but I have practiced so much that I have no need of the board for ones under 7 moves. After that, I can follow the game, but I cannot guarantee much accuracy.

One way to work on your visualization skills is to try to play a game against yourself, without a board, and just writing down the notation. After you finish the game, or get lost or confused, go and play it over on a board and look at how you do. It will take a while, but you will find improvement both in this excercise, and in your ability to find the correct moves in games based on deep calculation.

Sep-22-05  JoeWms: <ckr> <aginis> <artemis> Thanks, guys, for responding to my visualization query. I've bookmarked the janmatthies site.

BTW <> Do you prefer kibitzes of broad interest, that only peripherally relate to the game site that prompted the inquiry, be posted on the Cafe site instead?

Sep-22-05  wals: (artemis) thank you for the visualization training exercise

  patzer2: Today's puzzle solution 25. Qb2!! initiates a winning double attack, threatening to capture the Queen and Bishop or mate. Black's 25...Qe7, to protect both threatened pieces and guard against the mate is futile, since White's 26. Qxb7! establishes a second double attack (decisive loss of material or mate) with a clearly won game.
Premium Chessgames Member
  patzer2: <artemis> Good tips on visuzlization training! For those new to the study of practical Chess tactics and combinations, it is important to start off small. Clearly visualize the board position after each half move before proceeding ot the next half move. Practice with two and three movers before jumping to longer and more difficult combinations. Also, in order to avoid nasty surprises, make it a practice to clearly visualize the position of each piece left on the board at the end of a combination.

With practice on simple combinations, visualizing longer sequences will gradually become easier. You may have to look at the answer occasionally to a difficult problem, but with practice you won't need a board to mentally see and understand most solutions.

  Benzol: Got any suggestions for improving strategical ability?
Sep-22-05  alexandrovm: wow, beautiful!
Sep-22-05  Achilles: how to play this game?!?? hehehe../gg
Sep-22-05  avidfan: It is ironic that Black allows 27.Qxf7+ and 28.Qg8# when the very same Knight that protected the King from back rank mate stopped the defence by the Black Queen.

To <Benzol>:
A good intermediate book to study is A. Kotov's "Think like a GM". He discusses topics such as assessing a position, calculating candidate moves, how the middle game is characterised by the opening used, whether to open a position or keep it closed in going to the endgame.

Endgame study is most important.
A good site is - lots of tips! - one of which is to pin the King's Knight - a painful event which left a lasting impression on me.
