Man and machine finished in a dead heat as former world champ Garry Kasparov and the Israeli computer program Deep Junior finished their New York City match last week in a 3-3 tie.
Kasparov won Game 1 and took the play to the computer for much of the contest, but labored under the heavy burden of unpleasant memories from his 1997 loss to IBM's Deep Blue. He lost Game 3 from a superior position and declined to take risks in promising positions in games 5 and 6 against his unpredictable silicon adversary.
Programmers Amir Ban and Shay Bushinsky are to be commended for crafting a fighting, risk-taking style of play for Deep Junior, which continually surprised Kasparov and the assembled grandmasters with its anti-materialistic, unconventional decisions. Kasparov has taken some heat for failing to press on in the later games, and admitted his first priority was not to lose the match.
Considering all the grief (justified and unjustified) he took following the Deep Blue tilt, one is hesitant to blame him.
The match came down to one final contest between human intuition and mechanical calculation in Game 6, which we pick up from the diagram after Deep Junior as White has just played 23. Nd2-b3. Black's Hedgehog formation has been poised to strike for several moves and now Black plays a promising exchange sacrifice, undermining the White center: 23…Rxc3!? 24. bxc3 Bxe4.
Kasparov admitted later he missed Deep Junior's next move, a clever repositioning that holds White's game together 25. Bc1! Bxg2 26. Kxg2 Rxc3 27. Ba3 Ne8 28. f4.
Watching this game on ESPN2 with the sound off at a hockey rink in Laurel (it's a long story), I thought Kasparov actually resigned here when he and Ban shook hands and stopped the clocks. Actually, Black is probably better here, with a simple plan of walking his king to the center to support an advance of the central pawns.
On the other hand, these positions are like catnip for computers, who know how to play with a material edge, are tenacious defenders and can pounce on even the tiniest tactical oversight. My sense is that Deep Junior wasn't going to lose, and Kasparov only increased his chances of blowing the game and the match with every move he played. Kasparov made the right choice.

On the youth front, we have news of America's youngest grandmaster and the world's youngest grandmaster.
As we noted here last week, 15-year-old New York IM Hikaru Nakamura has eclipsed Bobby Fischer's record as the youngest U.S. player to achieve the grandmaster title, earning his third and final norm at the recent Category 10 Bermuda Chess Festival Grandmaster-B event. Nakamura finished second to Latvian GM Daniel Fridman with a 7-3 score.
Not only does he score well, young Nakamura plays a very attractive attacking brand of chess. His tough, last-round win over American master Michael Mulyar included a positional exchange sacrifice as in Deep Junior-Kasparov, but this time Black sees things through to victory.
Even with a grandmaster norm on the line, Nakamura doesn't shy from playing a sharp Sicilian line featuring castling on opposite wings. Black invites 15. Qxg7!? Rg8 16. Qh6 b4 17. axb4 Nxd3+ 18. cxd3 Rxg2, with the more dangerous attack.
When Mulyar declines, Black opts for a speculative exchange sacrifice, firmly seizing the initiative: 17. Bg5 Rxc3!? 18. bxc3 Nb6 19. Bc1 Na4 20. Ne2 Qc7, and White's busted queenside and the half-open c-file give Black at least dynamic equality.
With 25. e5 Be7, Mulyar decides to return the exchange in order to preserve his a-pawn: 26. Bc1 (Rh3? Bxa3 27. Ka2 Bb2 28. Rb1 Qa5! 29. Rxb2 Nxc3+ 30. Kb3 Qa4 mate) d4! 27. cxd4 Bxh1 28. Rxh1, but Black renews the attack with 28…b4! 29. Qe4 g6.
Mulyar actually does a good job of staying in the game until finally the Black pressure causes him to slip: 32. c4 Ndc5!? (not decisive, but hard to meet over the board) 33. dxc5 Nxc5 34. Qf3? (here 34. Qe3!, guarding the e-pawn, appears to hold; e.g. 34…Rb3 35. fxg6 hxg6 36. Rd1 Qb7 37. Rd2 Nxd3 38. Rxd3 Rb2+ 39. Ka1! Rb1+ 40. Ka2 Rb2+, with a perpetual) Qxe5.
Black's seizure of the long diagonal proves decisive: 35. Bxa3 Nxd3 36. Qxd3 Bxa3 (winning back the piece as 37. Qxa3 Qxe2+ 38. Ka1 Qxc4 wins, while 37. Kxa3?? Qa5 is mate) 37. Nc3 Qa5 38. Qc2 (Nb1 Bc1+ 39. Na3 Qe5!, with a killing check to come on b2) Rb2+ 39. Qxb2 Bxb2+ 40. Kxb2 Qb4+. Facing lines like 41. Kc2 exf5 42. gxf5 Qxc4, with a decisive material edge for Black, Mulyar resigned.
Across the ocean, 13-year-old Ukrainian Sergey Karjakin, recently crowned the youngest grandmaster in history, defeated 18-year-old Russian WGM Alexandra Kosteniuk 4-2 in a match sponsored by the Swiss tobacco firm Dannemann.
On Game 4 of the match, young Karjakin showed some nice tactical chops while outplaying Kosteniuk in a Sicilian Labourdonnais.
Black's queenside is already under some pressure when Kosteniuk unwisely steps into a minefield with 29. Qb6 Bxd5? (underestimating her back-rank weaknesses; 29…Qe7 30. Rxc8+ Rxc8 31. b5 axb5 32. Qxb5 Ra8 is still a fight) 30. Qxa6! Rxc1+ (not Rxa6?? 31. Rxc8+ Qf8 32. Bxd5+ and wins, but 30…Rcb8 31. Qd3 Bxb3 32. Rxb3 puts up a tougher defense) 31. Rxc1 Rxa6 32. Rc8+ Qe8 33. Rxe8+ Kf7.
Even with the queens off, Karjakin has one more trump to play: 34. Ra8!, attacking the hapless rook and forcing instant resignation. If 34…Rxa8, 35. Bxd5+ Ke7 36. Bxa8 wins the house, while 34…Rxa5 35. bxa5 Bxb3 36. a6 Bd5 37. Rb8 Ke7 38. a7 is equally hopeless. Kosteniuk gave up.
