  ENIGMAX: In this game, Black have build up for self a isolated pawn, removing the knight on f3 because that piece could be block your advance and that be the reason of can´t done 15. ... Nxd3 added up to fact of removal white´s castling protector. Colle´s system show demonstration by one of yours main player from the early half of twenty century.
Aug-04-05  mravikiran: after 21 moves, its typical chess player's puzzle "white to play and win". Considering the time at which it was played, its a novelty.

  DarthStapler: Very nice game by Koltanowksi
Sep-02-09  dumbgai: Gotta love double-bishop sacs on h7 and g7.
Sep-02-09  goldenbear: Does 26.Qc4 not help?
Sep-02-09  YoungEd: If 26. ...Qc4, then 27. Rxc4 followed by 28. Re4 leaves Black in much the same trouble, I think.
Sep-02-09  chesssantosh: why not 20 Bxh7+ sacrifice?wht did he make one move later?
Sep-02-09  MaxxLange: ^ 20 Rad1 prepared the crushing move 26 Rd4
Sep-02-09  Dimitrije Mandic: I just knew in advance that he would make a double Bishop sac!!
Sep-02-09  chillowack: I saw it coming too, Dimitrije--but the question is, can we make this sac happen in our own games?

I believe the mastery of this particularly sacrifice--i.e. being able to create it in our own games--will represent a step up in chess ability for any player.

The Bh7 sacrifice we've all done; but learning to sac on g7...that's another level of skill altogether.

Sep-02-09  birthtimes: Perfect co-ordination of pieces, as Capablanca would say, against a defenseless king's field...
Sep-02-09  birthtimes: Also a perfect example of overprotection, as Nimzowitsch would say, on the e4 square.

Truly, as Nimzowitsch stated, if pieces are are so engaged in overprotecting strategically important points, "they get their reward in the fact that they will then find themselves well-posted in every respect" to then branch out into "the form of a large radius of activity" (such as a form of a successful king-side attack).

Sep-02-09  buhomorado: Hey Birthtimes.. U are the famous astrologer... almost scape alive!

I borned January 23th , 1985 at 10:30 PM, i want to know where was my moon???

Please answer me...

Sep-02-09  birthtimes: buhomorado, email me at birthtimes@yahoo.com. You may get your information there, but not here on this site.
Sep-02-09  CakeMan: this was a boring and uninteresting game. Could have been played by A players. Everyone knows the double bishop sacrifice.

  Chessmensch: Does someone know how Colle is pronounced? Is is like doll or a Collie dog, or what. I've wondered for some time. Thanks.
Sep-02-09  Samagonka: What an attack! Black's helplessness in the end reminds me of Fritz whenever he gets cornered.

  Once: <Chessmensch: Does someone know how Colle is pronounced?>

I have always thought Collie, but have no proof.

Sep-02-09  PivotalAnorak: Chessmensch: like "Coll".
Sep-02-09  Gouvaneur: Well played attack by White, guess it was totally unexpected. Typical double bishop sacrifice, loving it.
Sep-02-09  310metaltrader: um, i do not see the resignation imperative. the king can escape still at the end. please show me a forced mate at the end?
Sep-02-09  310metaltrader: never mine, i see that black will have to shed another rook to avoid the next mating web
Sep-02-09  WhiteRook48: nice attack
Sep-02-09  SirChrislov: "Not all artists are chessplayers but all chessplayers are artists."

This is an excellent example on how to attack a castled position without a defensive knight on f6. thanks that the rooks were superbly placed on open central files (26.Rd4 was killer!!) and were able to cooperate in the attack. if not, the double bishop sac would've been useless and I'm sure Kolty would've passed on it.

"I never really deeply studied "My System", but I do recommend the section on Overprotection, it's very instructive. and I recommend Koltanowski's books, they're very good!" --Koltanowski
