chess tournament: Pentala Harikrishna beats Nihal Sarin , emerges joint leader

Malmo (Sweden): Grandmaster Pentala Harikrishna gave an endgame lesson to young Grandmaster GM Nihal Sarin to stay in joint lead after the completion of the fourth round of the TePe Sigeman & Co. chess tournament here. Harikrishna had the white pieces and in an Anti-Sveshnikov variation, Nihal equalised from the opening. However, Harikrishna always had a nagging edge, mainly stemming from his bishop pair. Nihal defended carefully and precisely and held the balance for most of the game, but this came at the cost of time. The critical moment came two moves before the time control when Nihal made an error and lost through a picturesque finale.  The ensuing bishop endgame are easily solved by a powerful computer, but a very hard nut to crack for an unaided human.
