34...exf5 [ 34...e5!? "has some apparent merit" (Fritz). This is very unclear - some lines appear to lead to a draw. Rublevsky needed a win to stay in the competition. 35.Qf1 Rad8 36.h4!?

  acirce: Very interesting. In the 33..e5 .. 37.b7 line I had overlooked 37..Qa5, only looked at 37..Qb4 which looks like a draw after 38.Qa7 Qd6 39.Qxb8 Qd4+ etc

37..Qa5 is indeed winning.

In the final position of the line efter <44.Qxe5> Black must be clearly winning with only a tiny little chance of White saving the draw.

Jun-27-04  Checkmate4327: I find Fritz's annotations very funny. Not the variations, just the random comments - an example is "cxd5 makes it even easier for Black" (like it was easy already!).
Jun-27-04  MoonlitKnight: I guess it's easy if you have no feelings and the true capability to calculate 15 moves deep at each move. :)
Jun-27-04  J.A. Topfke: I would add in my notes the alternative 14.h3? Nf6 (14Bxh3 15.Nxe4 [15.gxh3? Qxh3 16.f4 Qg3+ 17.Kh1 g5 ] 15Bf5 [15Bxg2 16.Kxg2 Qh2+ 17.Kf3 is only a draw] 16.Nd6+ Bxd6 17.cxd6 0-0 =) 15.Nc4 Bxh3! 16.gxh3 Qxh3 17.Nd6+ Bxd6 18.cxd6 h5 with the idea of 19Ng4 .
Jun-28-04  mynameisrandy: Philidor would love this game.
Jun-28-04  iron maiden: Definitely one for my Power to the Pawns collection.

  kevin86: A really nice example of the power of the pawns.

Just once, I would like to be able to think fifteen moves in advance! It' hard enough to follow a score past 7 moves or so.

Kozy comfy?

Jun-28-04  AdrianP: <Topfke> Thanks for pointing out the lines following 14. h3? - which illustrate the precariousness of White's position coming out of the opening.

<Acirce> The position at the end of your line is very striking, and it looks like Black has to take a perpetual - however, with the help of Fritz, I found the following pretty incredible line 42...Bxf5!? 43. Rc8 Qb2+ 44. Kg1 Qb6+ 45. Kg2 Qxc6+! 46. Rxc6 Rxb8 47. Bd3! Be6 when there is still play left for both sides.

I'll incorporate both the above into the web replay page at some point.

Jun-28-04  jaime gallegos: thanks AdrianP for your notes! I`m realized that I dont get autism to read all the telephone guide !
Jun-30-04  MoonlitKnight: Today's quote:

It is well known that two pawns on the sixth rank are stronger than a rook.

--- Du Mont

Sep-03-04  JustAFish: This game kind of depresses me. An alarmingly high percentage of my games go like this (that is, I lose like white lost). In the annotations there are large number of places where small improvements could have been made, any of which would have held for black, or even won. (Acire's line, for instance). Sigh.
Dec-05-04  tex: Wow, highly amusing game well worth playing through. If it was played by two world top 5 players people would be calling it game of the century.
Dec-21-06  puninski: What a killer match !!!!
Great stuff from Zdenko !!!!
Nov-05-07  Elxiddicus: I'm probably just not seeing something here, but doesn't 20. Bf1 win black's queen?

  Pi Guy: <Elxiddicus: I'm probably just not seeing something here, but doesn't 20. Bf1 win black's queen?>

If 20. Bf1, black plays 20...Nxf2, threatening the white queen. If white captures the knight, black has won the exchange and the queen escapes along the newly opened diagonal. If white captures black's queen, white captures black's queen, once again with the net result of losing the exchange.

Jul-09-12  vinidivici: why not 19.fxe4 ?
Jul-12-12  vinidivici: whats wrong w/ 19.fxe4 ?
Jul-12-12  dougiejfresh: 19. fxe4 weakens the kingside and invites 19...h4. White can try a few responses, but defense will be difficult:

a. 20. Rf2 hxg3 21. Rg2 Nxe4. White is in a serious bind, and will lose at least the exchange.

b. 20. Qe1 Nxe4 21. gxh4 Bxh4. Again, white is in trouble. Any move other than 21. gxh4 allows 21...hxg3 and a devastating attack.

c. 20. gxh4 Rxh4 21. Rf2 Nxe4 followed by Qxe3.

d. 20. g4 Qxe3+ followed by 21. Nxe4

In any event, it seems White will lose at least a few pawns and the exchange.

Jul-13-12  vinidivici: thanks. thats deep
