Kibitzer's Corner
< Earlier Kibitzing  · PAGE 1 OF 2 ·  Later Kibitzing>
Oct-20-03  AdrianP: The result serves White right for his earlier pawn structure...(c. move 20 onwards)!... although he only lost through an unfortunate tactical oversight.
Feb-09-04  Hinchliffe: AdrainP that was a fairly basic tactical oversight though. Rather pleasing, in a sadistic kind of way, to observe that even top notch players are capable of making errors in calculation in comparatively straightforward situations.
Feb-10-04  AdrianP: <Hinchcliffe> I agree ;-). In fact, it seems to me that most top players make more "simple" tactical oversights than "complicated" tactical oversights.
Aug-04-04  poktirity: Easier than yesterday...

  cu8sfan: It's Wednesday and I'm still in! Then again, I was looking for a ♕-sac and ♘-fork so that was easy to spot.
Aug-04-04  cjhasbrouck: Got it easily. :) I love Chess
Aug-04-04  HailM0rphy: The last 3 prob should classified as 'mondays' but then again I dunno if q sacs and forks can be much harder to find..makes me ankshus (I'm in 3rd grade spelling) for Sunday ;)

  Sneaky: Whenever chessgames posts a bunch of problems all of the same tactical motif, it's always easier than normal. I bet if this problem showed up on Wednesday of last week a lot more people would be scratching their heads.

But hey, there is value in this. We look at this and say "Oh, easy, another fork combination." So when we're in the big tournament we'll look at the board and say, "Oh, easy, another fork combination."

Aug-04-04  HailM0rphy: <Sneaky> Whenever I look at the board in a big tournament I'm usually thinking "I'm screwed"

  Gypsy: <¬†Hinchliffe: AdrainP that was a fairly basic tactical oversight though.> Perhaps a basic oversight, but White definitely had some problems on his hands:

I. White bishop can not leave the f1-a6 diagonal. Behold 37.Bxa4? Qd3+ 38.Kf2 Qe2+ 39.Kg3 Qg2+ 40.Kh4 Qh3+ 41.Kg5 Qh5# (or 41...f6#) for instace.

II. If White just moves his bishop between the "safe" squares a6,b5,c4 and if his queen either stays put or makes inocuous moves as well, then the Black king will march to g3, say, after which the life of the White king would be cut short by the combined force of black Q+N+K.

III. Therefore the relatively best may be the immediate 37.Qc4!? Black then should continue his attack. The following variation shows how much poison is still left in the attack 37...Qd1+ 38.Kf2 Qd2+ 39.Kf1 Qxb2 40.Bxa3 Qg2+ 41.Ke1 Qxf3 42.Be8? Nd3+! 43.Kd2 Qf2+ and, suddenly, white looses his queen either after 44.Kxd3 Qf1+ or after 44.Kd1 Nb2+. (The position after 43...Qf2+ is rather pretty!)

IV. But black should not exchange the queens 37.Qc4!? Qxc4 38.Bxc4 a3!? The reason is that while after 39.b3? Black should to win, he would be on the verge of a loss after 39.bxa3! The key difference is that afer 39.b3?, white King has no path to attack the b-pawn, but after 39.bxa3! bxa3 the King can- and should pick up the a-pawn.

Aug-04-04  rclb: The problem with these themes is that instead of being a genuine puzzle where one has to think for at least a few seconds and often a few minutes, I got this one in 0.1 seconds and it really spoils the fun. Themes are nice, but please not such an obvious theme!!!
Aug-04-04  PinkPanther: Dear god that was an easy one.
Aug-04-04  Larsker: Elegant
Aug-04-04  ArturoRivera: Its easy but it exersice our mind, took me around 3 seconds beacause i had the words of sneaky in my head <all the week will be fork's!>
Aug-04-04  Saruman: I solved this problem faster than Sauron converted me!
Aug-04-04  killaa: I'm with you, <Sneaky>, I guess the idea isn't that we are all GM's if we can get the solutions so much as to aid us to think along the right lines and try to end up at the situations they show us - and then be able to finish it off!
Aug-04-04  blore: Actually this fixed theme is a great thing to improve all our chess! It is true that random puzzles are more interesting but the same thing dinned into one's head the whole week will ensure that such situations arising in tournament games can be exploited after this intensive training!
Aug-04-04  white pawn: I like the fixed themes, too. Like you said <blore>, it enforces the idea, so that in a live game, the idea will come into our heads more quickly, even if a queen sac/knight fork isn't possible, trying to think of one couldn't hurt, right?
Aug-04-04  rclb: <saruman> so in less than 2000 years or so then?

  kevin86: This one was easy;I looked for the fork and found it.If a player subconsciously looks for a tactic,he may find the winning move-it is called habit.
Aug-04-04  blore: Yes <White Pawn> I agree with you
Aug-04-04  notyetagm: Nice, 37 ... Qg1+!! Kxg1 Nxe2+ Kf2 Nxc1 winning a piece. This is how you use your knights. A beautiful <knight fork combination>.
Aug-04-04  Whitehat1963: Surprisingly I got this one immediately. Is today Monday? Yesterday I thought it was Thursday. I wasn't even close.
