White to play,...

At first glance, it looks farely simple and drawish.
But the way white turns around the situation using king versus king opposition is amazing!

Right now,I am not financially strong enough to buy Rybka.
Please check this position with best version of Rybka.
What does Rybka has to say on this?

For solution and complete game,check the link...It is from Montreal International Tournament 2007.

Athlon 3500+ 2.21 GHz:
Rybka 2.3.2a.x64 in less than a minute comes up with

(+2.83, d29) 1.Rxe6 fxe6 2.g4 hxg4 3.Kg3 Kf7 4.Kxg4 Kxf6 5.a4 Kf7 6.Kg5 Kg7 7.a5 Kf7 {(0:00.47)}

and then the score increases till +3.8

Rybka 1.2i(not the strongest Rybka generally) finds this in 4 seconds and sees that it is good for white after 3 minutes.....
If i left Rybka a ply more i think a score of +3 or more would come.....

Really thanks George and Zruty for your so tiny[/i] explanation about what engines say.

It must be really amazing to work with an engine on situations.

"Yace 0.99.87" seems to work like rybka winfinder.

By the way, if anybody has Rybka Winfinder, will he tell how quickly that operates to reach the solution.?

By the way This game was played by a most promising GM from India. Lets just look out for this lad..."Pentala Harikrishna"

You might be knowing only Vishy Anand and Sasikiran as some who bears enough potential
to make his place in International Chess.

He has shown his metal against our favorite players for example,...

1. Alexander Morozevich

  please look keenly for the move 28)...c2!!!

  http://www.chessgames.com/perl/chessgame?gid=1442764

  see the knights dance in the end!

9. Luke McShane : - Enjoy Pawn storms in the end!

  ...Just for further curiosity check the number games played by Harikrishna and our
Love Carlsen till now,

  1. Harikrishna: -  428 odd games in a span of 10.5 years(1996 to 2007)...

Check - http://www.chessgames.com/perl/chessplayer?pid=49246

  2. Magnus Carlsen : - 615 games in a span of 6.5 years!(2000 to 2007)

check - http://www.chessgames.com/perl/chessplayer?pid=52948

.... Only reason is Lack of sponsorship and nothing else.


And a very sad line I saw on Wikipedia,

I Just read "Lack of sponsors may force Harikrishna to quit chess"

Check: - http://en.wikipedia.org/wiki/Pentala_Harikrishna
          see this in External Links Tab
Also check : - http://www.hinduonnet.com/2004/11/08/stories/2004110808732000.htm

If he quits chess just because of sponsorship it will be really shame to Chess & Chess Lovers.

So many flower don't flower just because they got them-selves in desert Land! We should arrange
some water them which their birth-right.
Huh!

We will not forget it because of the huge amount of blunders occurred to it? :)

>8. Giovanni Vescovi : -You won't forget this game either!

Same here.
These are really good attacking and complicated games, but full of mistakes...... :(

>7. Lenier Dominguez-Perez : - see his combinations...
>http://www.chessgames.com/perl/chessgame?gid=1330530 


Many tactical mistakes/blunders here too mainly from his opponent.....

>If he quits chess just because of sponsorship it will be really shame to Chess & Chess Lovers.


Yes it would be a shame....
Parent - By Priyanvada (***) Date 2007-07-24 15:46
  May be my selection be poor...but which human plays perfect Chess?
  also  what about other games...!

  ...You can  quickly do a blunder check using Rybka or Yace,...but you need have something in you to prove on Board!

     Still quality of the game is not the point to be made here,.. someone of some caliber quitting chess because
of lack of resource is really the Sad Part.

warm regards
