Kibitzer's Corner
Aug-15-07  Guguni: Anyone sees a continuation of the attack with the queen and the rook? As I see it after the exchange of the queen and the rook three extra black pawns beat the extra bishop of the white. It looks like the bishop will be able to stop the a4 pawn but the king pawns will march and queen.
Aug-15-07  paulgrow: Looks like a certain endgame win after rook and queen trades. White can do nothing but wait, the black king will go to e3 and trade the h pawn for the f3 pawn, after which the f pawn will queen (unless the bishop tries to stop it, then the a-pawn will.)
Aug-15-07  MostlyAverageJoe: Very educational ending.

Incidentally, position after 39. Rxe4 would be a good (and not too difficult) puzzle. It seems that black has a much better move than what was played in the game: 39 ... Qh4! looks like a major threat. What can white do here? Perhaps some ineffective check with a rook, and the black brings Rg5, and white is in deep trouble:

Hiarcs evaluates the above at (-7.45), an easy win. Then again, Rg5+ is not shabby, either (-3.85). Both 16-ply.

Aug-15-07  spidi: 44.Ke2 Rxe2+ 45.Bxe2 Qxf1 46.Bxf1 a3 47.Bc4 h5 .. and easy win.

MAJ, what does Hiarcs says to the possibly best reply 40.♕f2? I do not see an easy ......

Oh wait, no, now I do. I thought <40....♖g5+> wasn't winning because of 41.♔f1. Think that I was wrong, as 41....♕h1+ 42.♔e2 ♖g2 wins badly. I guess Black didn't see that either.

Aug-15-07  Zzyw: I find it interesting that my Fritz 9 rates the final position as -0.25 at 14 ply depth. But after exchanging heavy pieces and sliding forward it is an easy win for black.

Could anyone with a strong engine tell me how they rate the final position?

  Marmot PFL: Dzindzi finds a cute endgame win. 40...Qf8 was quicker but probably time was a factor at that point.
Aug-15-07  RandomVisitor: <Zzyw>In the final position, after the exchanges, Rybka scores the final position at -5.00 or so. The Black queen rook pawn ties down the white bishop and Black can get a pair of passers on the Kingside. White has no effective hope for counterplay.

  kevin86: I looked at the ending and the result seemed iffy-except that black has TWO passed rook pawns-while the bishop is occupied against the a-pawn,the king can usher home at least one pawn in a 3-1 advantage.

White seemed to hold the game as long as his pawn chain held;when it collapsed,his game went with it.

Aug-15-07  unixfanatic: Amusing pun on "Roman nose"
Aug-15-07  vajeer: black queen moves on 41st move, its so effective from d8!

  fm avari viraf: It is just an elememtary win for Black after the exchange of Queens & Rooks inspite of having an extra Bishop. The strategy would be Black King will march into the enemy camp & pushing the a & h pawns at an appropriate time where White is defenseless. Rodriguez, sensing his dark future resigned.
Aug-15-07  Fezzik: Curiously, Chessbase has one extra move each, 44.Ke1 Rxe2+ before White resigns. This of course is the simple win that FM Viraf mentions.
Aug-15-07  ALEXIN: I don't understand what happened.

If black didn't see that he was winning after exchanging heavy pieces, why not to reach the draw with 43.Qh4+ ?

About the endgame:

In my opinion, this is not an "elementary" win. Habitually, in such position who has an extra piece wins. This is an exception.
