  SwitchingQuylthulg: It appears that 28...Ng6 (as pointed out by engines - not that it's a move no human would ever see) would have been an instant win because of the threat ...Rh8. Even after that missed opportunity, Black seems to hold a nice edge. For the last ten moves or so, both sides were practically reduced to the 10-sec movely increment, which explains the rather weird play in the ending.

  Troller: Didn't Rublevsky actually lose on time? Not that it matters of course.
Jun-14-07  Raginmund: two Scotch in 3 games... why??? Rublevsky needs opening repertoire, how can someone be world champion with Scotch???

a very well deserved loss

congrats Grischuk

Jun-14-07  Tomlinsky: <how can someone be world champion with Scotch???>

Simply beatiful

Jun-15-07  notyetagm: <syracrophy: The final position after 39...Nxc3+!! 40.bxc3 Qb1# is incredible>

Yes, I added this splendid example to my <PINS> game collection.

39 ... ♘d5xc3+! is a beautiful example of a <PIN AGAINST A SQUARE>. The White b2-pawn is needed to <BLOCK> the b-file, else Black delivers the snap mate ... ♕b5-b1#.

But as I like to say, <BLOCKING A LINE IS A FULL-TIME JOB>. Since the White b2-pawn must <BLOCK> the line b5-b1, it cannot also <DEFEND> the c3-forking square of the Black d5-knight.

Jun-15-07  notyetagm: <Raginmund: two Scotch in 3 games... why??? Rublevsky needs opening repertoire, how can someone be world champion with Scotch???>

Got to give credit to Rublevsky's amazing skill. How he is able to have such a high rating (2660+) with such a predictable opening repertoire is beyond me.

He plays only the Scotch Game verus 1 ... e5, plays 3 ♗b5/♗b5+ versus Sicilian, plays 3 c3 versus e6-Sicilian, plays Queen's Gambit Accepted versus 1 d4, etc.

Rublevsky may have the most predictable opening repertoire in the world: that is not a good thing.

Jun-15-07  Open Defence: < Tomlinsky: <how can someone be world champion with Scotch???> Beats me...

http://www.chessgames.com/perl/ches...; with a fair amount of wins too hehehehe.....

Jun-16-07  notyetagm: 26 ... ♘d5-e7! is a lovely tactical shot by Grischuk.

This knight move indirectly protects the Black e5-pawn. How? If White grabs the Black e-pawn with 27 ♕f5xe5??, then he loses a piece(!) to 27 ... ♖d6-e6!.

(VAR) Position after 27 ♕f5xe5?? ♖d6-e6!

The White e5-queen is attacked by the Black e6-rook but if she runs away the White e4-knight hangs. The only squares to which the White queen can move and still <DEFEND> the White knight (d4, d5, f5, f4) are -all- covered by Black's pieces and pawns.

A nasty little tactical trap by Grischuk and played in a rapid game no less. This is a great example of the incredible tactical ability of the 2700s.

Feb-23-10  AccDrag: <notyetagm> Rublevsky may have the most predictable opening repertoire in the world: that is not a good thing.

Fischer did OK with quite a limited repertoire, especially by today's standards. Tiviakov also avoids main lines often, and he isn't too shabby.

  Once: How about 39. Qc2? To be sure, black can still cause mischief with 39...Bb6 threatening Ne3+ but it has to be better than "resigns".
Feb-23-10  Dupin: As has been mentioned, 28...Ng6 would pose a great problem for white. I think the best answer white has to this move is 29.Qh2 Rh8 30. Qg1, which would let the queen escape and defend the rook. However, black will then have the possibility of playing Bxf2, deflecting the queen on g1, and the queen has to take, allowing black to take the rook on h1 (30... Bxf2 31. Qxf2 Rxh1). The result of the clash would be an exchange and a pawn up for black, the equivalent of a piece.
Feb-23-10  wind mind: Dupin, in your line, after 30...Bxf2, you didn't consider 31. Rxh8.

Didn't analyse further, but in that case I guess white would keep the material, at the cost of position and initiative

Feb-23-10  Andrijadj: If this is Potter Variation,where is Voldemort's?:)
Feb-23-10  goodevans: <Dupin>, <wind mind>,

The Ne4 protects f2 so I think it's necessary to give the N a kick with 28 ... Ng6 29 Qh2 <f5> first.

  playground player: <Raginmund> So what's wrong with the Scotch Game, that high-level players shouldn't use it?

I'm waiting to see someone use the Polish Opening in championship play. Maybe that won't happen until Yuri Lapshun is a GM.

  kevin86: Black will either win the queen by fork or the king by mate.
Feb-23-10  David2009: <Once: How about 39. Qc2? To be sure, black can still cause mischief with 39...Bb6 threatening Ne3+ but it has to be better than "resigns".>

Qe2? was a blunder losing immediately to Nc3+ <Troller: Didn't Rublevsky actually lose on time? Not that it matters of course> but even after the better 39.Qc2 White is struggling after 39...Qc4.

His King is vulnerable whilst Black's is secure, his R cannot effectively defend, and his Pawns cannot be pushed. Meanwhile Black is threatening Qxa2. One possibility is 40.Qb1 Bg5 41.g3 Ne3+ 42.Ke1 Qd5 43.Ke2 Nf5 and Black is threatening Qd2+ Kf1 Ne3#. Other defences seem to lose even faster.

On-line Crafty link to the position at move 39 for enthusiasts interested in practising unequal struggles: http://www.chessvideos.tv/endgame-t... You are white, drag and drop the move you want to make.

Feb-23-10  psmith: <RandomVisitor>
"36. Kc1="
why "="?

How about 36. Kc1 Qe7?

Feb-23-10  RandomVisitor: <psmith>After 36.Kc1 Qe7 37.Kb1 Qe1+ 38.Qc1 Qe2 39.a3 Qxg2 we have 2 pieces versus Rook and pawn (and queens). Turning to my Basic Chess Endings, p.449, we have:

"In the ending, two pieces are approximately equivalent to a rook plus one pawn. However, the nature of the pawn configuration may force a change in this estimate. When the pawns are scattered or offer convenient targets, the pieces are superior; when the pawns are solid, a rook will usually be able to hold its own. A great deal depends on who has the initiative; this consideration is much more prominent here than any other ending."

So my thinking is that if queens are exchanged and white can keep his pawns on the opposite color of the bishop, he might hold. Just my two cents.

Feb-23-10  WhiteRook48: harry??
Mar-15-10  gilbav: I submitted this pun for the Pun Contest long ago. Just mentioning it for posterity, it's not that I think it's an exceptionally wonderful pun or anything.
