  Mateo: A masterly example of a dark square strategy combined with a kingside attack. Harikrishna played consistently to open the long diagonal to his Bishop in brilliant style.

Jun-27-06  notyetagm: From chesscenter.com:

<A murderous attack of a different kind was conducted by the Indian GM Pentyla Harekrishna in the sixth round of the Foros tournament where the Russian champion Sergei Rublevsky assumed the lead by defeating Viktor Bologan with black.

Jun-27-06  notyetagm: I had a major argument some months back with <LMAJ> over a simple <LINE-OPENING SACRIFICE> that he wanted to give !! to. Since it was a check against a stalemated king I disagreed.

Here 25 ♘h6+!! fully deserves !!. It is in no way as obvious as a check against a stalemated king.

In an opposite-colored bishop middlegame, you -must- attack on the color complex that you control, even if it means a sacrifice of material. That is -exactly- what Harikrishna does here.

Best opposite-colored bishop attack I have seen all year. Magnus played a good one against Naiditsch at Corus this year too but that one was a desperation attack in a lost position that succeeded only after Naiditsch blundered terribly with a natural move.

  Ron: Not only is 25 Nh6 a great move but I think the previous move 24 f5 is pretty good. If, after 24. f5, black plays Bxf5 then play could go: Rxg7+ Rxg7 Nf6+ Kf7 Nxd7 Nxd7 Bxg7 Kxg7
Jun-28-06  notyetagm: <Ron> Yes, this is one of the best kingside attacks I have seen all year.
Jul-15-06  samsal27: Fantastic game by Harikrishna to show that he is one of India's brightest stars after Vishy Anand ...
Aug-29-06  Manic: How come this game has not been added to Harikrishna's notable games selection? It's a stunning attack. Perhaps Chessgames has not seen it yet, but there is no doubt that this deserves to be added to the notable games of Harikrishna.

22. Rg5!
24. f5!
25. Nh6+!!
28. Rxf5+!
32. Re7!

May-24-11  sevenseaman: Brilliant and gutsy play by Pentala; makes Mamedyarov's FIDE rating look inflated.
Feb-05-15  sinusitis: Harikrishna analyzes this game here:

http://new.livestream.com/gibchess/...

Feb-05-15  shivasuri4: <sevenseaman>, Mamedyarov was rated 19 points above Harikrishna at the time the game was played, and the latter played White here. Nothing inflated about the rating.
