JAMAICA enjoyed their best day at the 40th World Chess Olympiad yesterday in Istanbul, Turkey, as both the men and women team won easily in the 10th round.

For the second day in a row, the Jamaican girls registered a 4-0 victory after blanking Angola.

WFM Deborah Richard-Porter (4.5/9) easily out manoevred Sonia Rosalina for her third win in nine games, national champion Krishna Gray (2.5/8) broke her four-game losing streak with a well-worked win over Irineia Gabriel, Melisha Smith (3/5) dismantled Fina Carlos' Horwitz Defence in 34 moves, and Ariel Barrett (3/7) expertly used the Lipnitzky Variation of the Sicilian Defence to overcome Caxito Esperanca.

In the Open section, Jamaica beat Liechtenstein 3-1. FM Warren Elliott (4/9) made short work of Fabian Ferster by refuting his Marshall Gambit in only 23 moves; IM Jomo Pitterson (4/8) won for the third time in eight games as he patiently outplayed Mario Kobler; co-national champion Andrew Mellace (3/6) stayed on course for his Candidate Master title when he stun Kur Muendle with a relentless King-side attack; and co-national champion Damion Davy (4/9) lost his second game in a row as his King fell captive to the two marauding Knights of Marcel Mannhart.
