Aug-15-03  ughaibu: It's a great attack but the opening doesn't seem very relevent. Isn't it a QGD exchange rather than a Nimzoindian?
Aug-15-03  Benjamin Lau: Well, all the d4 openings are related in subtle ways, so I guess you could think of it that way too. Since you reach the position from a Nimzo though, I just think of it as a Nimzo, lol. ;-)
Jun-11-05  vonKrolock: Lipnitsky appears here as master of the à-la-outré stormy assault<27...♘e5>! Stormy clouds gathers around white’s castle

<28.♖ae1> Or.f4 ♘d3 29.♕d3 d4!?

<30...♘f3>! A nice blow, with surprise effect..

<31.♖e2> After 31.♔f3 ♘e4 32.♔e2 ♘c3 33.♔d2 etc – black recovers the ♙ in ‘h3’ and exerts some pressure from the bases ‘d4’ and ‘c3’

<31...♘g4> Or 31...♘d5 32.♗c4! best – otherwise ♘c3 would be quite unpleasant

<33...♕c8> Threatening already a mate in three (♘e3 etc)

<34...♘gh2>! A most extraordinary situation - the dark cavalry stormtroopers deep at heart... ...

<36.♘h2>?! ♙ossibly 36...♘h4 was the best move here, conducting to a draw in the main lines

<37...♖f3>!!? White’s ♔ nightmare now is full of dark ♖♖s...

<38.♘f6>?? Sudden, expected but also undeserved denouement – ♔otov had the winning 38.♘g5 at hand}

Jun-11-05  fgh: Beutiful centralization game and knight invasion.
Jun-12-05  DP12: fabulous 38.Ng5! looks decisive
Jun-13-05  vonKrolock: Yes, white is threatening mate and at same time defending 'h3' - evidently Kotov was in deep clock-trouble...

  FSR: 39...Qh3+! and 40...Qh1#. First!

  Phony Benoni: The queen must visit odd corners of the board to pull this one off.
Jul-01-14  TheBish: Kotov vs Lipnitsky, 1951

Black to play (39...?) "Easy"

It's mate in 2.

39...Qh3+! 40. Kxf3

Or the more mundane 40. Kg1 Qh1#.

40...Qh1#. Second!

Jul-01-14  Chess Dad: 39... Qh3+

40. Kxf3 Qh1#

40. Kf1 Qh1#

40. Kg1 Qh1#

The key for me was when I noticed the d4 pawn controlled e3 and therefore it didn't matter if I allowed Kxf3.

(It also helped that white is threatening about 3 different mates unless I do something forcing.)

Jul-01-14  MountainMatt: I kept looking for a way to make an "active" sac work (a la Rxf2 or Rxg3), but it turns out a "passive" sac is the winner - 39. Qh3+ Kxf3 (in fact, any king move) 40. Qh1#.
Jul-01-14  M.Hassan: "Easy"
Black to play 39...?
Black has a Rook for a Bishop+Knight.
If black slips and takes the Kight:

39............gxf6??
40.Re8+ Kg7
41.Re7+ Kh8
42.Rh7#
Right move is:
39...........Qh3+
<if 40.Kg1 Qh1#>
40.Kxf3 Qh1#
Mate in 2 in both lines

Jul-01-14  M.Hassan: <Chess Dad>
39....Qh3+

40.Kf1 NO

Jul-01-14  Cheapo by the Dozen: Various cliches apply, such as "Always check; it may be mate!" or my teacher Arthur Spiller's favorite "Queens move backwards!"

But why didn't White play Ra1 a move earlier?

Jul-01-14  dfcx: 39...Qh3+ and mate next with Qh1 no matter what white plays (Kxf3 or Kg1).
Jul-01-14  Chess Dad: <M.Hassan>

<40.Kf1 NO>

Whoops. Yep, Kf1 is not legal. My mistake.

Jul-01-14  jffun1958: Black K is mate on f3 with a diagonal check from h1:

39 ... Qh3+ Kxf3/Kf1/Kg2 40 Qh1#

Jul-01-14  agb2002: Black has a rook for a bishop and a knight.

White threatens 40.Qg8#, 40.Re8# and 40.Nxg4.

Black can deliver mate in two with 39... Qh6+ 40.Kxf3 (40.Kg1 Qh1#) 40... Qh1#.

Jul-01-14  Stormbringer: Interesting how white lost dominated the white diagonals but still lost on the white squares.
Jul-01-14  RookFile: Evidently Kotov blundered, and missed the win earlier. Lipnitsky didn't miss his chance.
Jul-01-14  whiteshark: <39... Qh3+ 40.Kxf3 Qh1#>, and that's it.

  Sally Simpson: Smashing game with a lot of cute ideas and towards the end a nice position to mess about with. The winning combo is good, Black sacs one Rook (refused) so he sacs the other Rook. Game Over.

Back here.

Instead of the attractive looking 38.Nf6 the move 38.Ng5 is the winner.

White has mating threats, hits the f3 Rook and stops the Rxh4+ and Rh3 mate idea.

Often missed Legacy tucked away in there, some players stop looking because the h7 pawn has moved but...

38...Rf8 to save the Rook and stop the back rank mates.

39. Nf7+ Kg8 40. Nxh6+ Kh8 41. Qg8+

41...Rxg8 42. Nf7 mate.

Speaking of the Philidors Legacy stumbled upon this yesterday on RHP.

Black to play. He saw and played the legacy

And speaking of two Queens. Do you want to see a total heart breaker?

Actual game, your opponent has two Queens, you have none. You can under promote not to a Rook, but to a Bishop and checkmate. The lad chose the mundane way.

Jul-01-14  morfishine: 39...Qh3+ 40.Kxf3 Qh1#

The pawn on d4, sealing of e3, makes this possible

*****

Jul-01-14  Nick46: It fell into place after I set up the ole fashioned board and pieces.
Jul-01-14  stacase: Took me way too long worrying about White's mating attack and failing to see that Black had a Pawn on the job blocking the White King's escape route.
