Viswanathan Anand put behind the disappointment of the World Championship loss and started his campaign by first beating England's Luke McShane and drawing with Michael Adams, another Englishman, in the preliminaries of the London Classic.
Five-time World champion Anand, who turned 44 on Wednesday, did well to beat McShane, who is known as the world's strongest amateur. He then followed it up with an easy draw against Adams to share the lead with the latter.
With four rounds still to come in the prelims, Anand and Adams have four points each from two games under the soccer-like scoring system in place in the tournament.
McShane is not far behind on three points, while Andrei Istratescu of France is yet to open his account.
With 16 players taking part this year, the Classic is divided into four groups and the top two from each group will reach the knock-out stage after a double round-robin.
Having made a good start, Anand is almost sure to find himself in the knock-out stage, reserved for the top two finishers in each group.
Anand started the day as black against McShane and opted for the Caro Kann defense. McShane, agile and innovative as ever, came up with a fine pawn sacrifice in the early middle game, putting Anand in a spot of bother, and won a rook for a minor piece and pawn.
The English Grandmaster was in control of the board but not on the clock as the game progressed. Showing some brilliant counter-active measures, Anand converted it to a winning endgame with his passed pawns in the centre ruling the roost.
In the second game, Anand could not do much as white against Admas out of a Catalan opening. The pieces got traded at regular intervals and the peace was signed after 40 moves.
The other three groups saw the emergence of clear leaders on day one although it was a pretty tense day.
Russian Vladimir Kramnik was very lucky to score over compatriot Peter Svidler in the first round of the 'B' group and then steamrolled over wild card entrant Jonathan Rowson of England to maintain a clean slate.
Rowson is currently second on three points after he recorded a victory against Matthew Sadler of England.
Former World Championship challenger, Boris Gelfand of Israel scored a fine victory over Judit Polgar of Hungary in the first round and then crashed through the defenses of Gawain Jones of England to lead group 'C' with two wins.
Fancied American Hikaru Nakamura conceded a draw to Jones in the opener and then defeated Polgar to remain a close second.
In group 'D', Fabiano Caruana of Italy scored two victories at the expense of Emil Sutovsky of Israel and Nigel Short of England. English David Howell is in second spot on four points.
