Jul-21-05  EmperorAtahualpa: Excellent game by Konstantinopolski!

34...Rxg2!

Oct-09-05  BaiKosta: Great game in byzantine style!
Oct-09-05  dakgootje: yes very nice game indeed
Mar-18-06  ltsiros: Also to note is the Bishop manouver Ba6-d3-e4, attacking the target at g2.
Dec-10-07  refutor: great game by konstantinopolsky

<34. ...Rxg2!>

i thought the ...Ne4 followed by ...f5, ...g5 and ...f4 was great, especially against an opponent of the strength of keres.

Jan-14-08  vintage geisha: Can anyone explain what happens if black played 15)...Nxc5?? Can't black win the pawn safely, meeting 16)Nxe5 with 16)...Qxe5? Sorry if this is really simple- I don't have a chess computer at the moment
Feb-19-09  ALwoodpusher: <vintage geisha> 15...Nxc5?! would allow white to post a bishop to d6, i.e. 15...Nxc5 16.Be3-Ne4 17.NxN dxe4 18.Bc5
Feb-19-12  The Curious Emblem: I don't like 8. c5. That move does not help White with his Queenside attack, as Black can prepre an ... e5 breakthrough in the center and nullify it. White had no concrete plan from there on in the game except to play defensively. A better move would be 8. Bg5, if White is willing to accept an Isolated Queen Pawn, which is perfectly fine here.
Feb-21-12  Dr. Siggy:

"This position which ocurred after White's 40th move is a study in the utilization of passed pawns. Black has won the Queen for Rook and Bishop, but White's QBPs are difficult to stop and it is only by using his own pawns in conjunction with mating threats that Black can win the game. The play is very delicate."

(William Winter, "Chess for Match Players", Bath 1951, page 277.)

Dec-11-16  Chizoad: I'm trying to learn to play against the Caro-Kann, and I don't understand 7.a3 in this game. 10 years later, Keres played another game that had the same position on board, but via transposition. Again, he had to play defensively and lost thanks to Tal's incessant pressure.

Keres vs Tal, 1957

It's probably not good to lose two instructive games from the same position.

It seems to me the more active plan is to limit Black's ability to attack white's d4 pawn, which cannot be defended by a pawn. For a plan along those lines, look at Botvinnik vs Konstantinopolsky, 1943 in which Botvinnik trades off the dark squared bishops, then the knights, leaving black with the bad bishop versus his good knight.

Apr-24-19  Swedish Logician: <Dr Siggy>, after 40. _ Qb1 + white has some options.

A) 41. Rc1 Qd3 42. Kf2 Qe2+ 43. Kg3 Qg2+ 44. Kf4 Qg4#

B1) 41. Bc1 Qe4+ 42. Be3 d4

B2) 41. Bc1 Qe4+ 42. Re3 Qc2 43. Bd2 f2+ 44. Ke2 f1=Q+ 45. Kxf1 Qxd2 46. c7 Qc1+ 47. Ke2 Qxc5

the same method works when the white pawn tries to run earlier

C) 41. Kf2 Qh1 - threat 42. _ Qg2+ 43. Ke1 Qe2# -

C1) 42. Bg5 Qg2+ 43. Ke3 Qxg5+

C2) 42. Bf4 Qg2+ 43. Ke3 Qe2+ 44. Kd4 Qe4#

C3) 42. Bh6 Qg2+ 43. Ke3 Qe2+ 44. Kf4 d2+ 45. Re3 f2;

C4) 42. Bd4 Qg2+ 43. Ke3 Qe2+ 44. Kf4 Qe4+ 45. Kg3 Qxd4;

C5) 42. Kg3 Qg2+ 43. Kf/h4 Qg4#
