Chess: How does White win?

FIRST contested in 1884, the Scottish Chess Championship ranks as one of the world's longest-running national tournaments. The 118th Scottish Championship gets under way tomorrow at the LifeCare Center in Stockbridge, Edinburgh.

Save for the Scottish Centenary Championship of 1984, it has only recently changed format from a closed event to an international open. The foreigners play hors concours – the highest-placed Scot taking the national title and going on a roll of honour that started with John Crum 126 years ago.

Local grandmaster Keti Arakhamia-Grant is this year's top seed. In 2003, Keti came equal first alongside seven-time champion Paul Motwani, to become the first woman to win the title. This year, Keti is the odds-on favourite to win her first outright title. But she won't have it all her own way, because the veteran two-time champion, IM Craig Pritchett is her main rival – and he's the in-form player, after recently picking up a gold medal for his incredible top board performance of 7/9 at the European Senior Team Championship.

The Championship will run through to Sunday 17 July, 1pm-7pm each day. Spectators are welcome, and it's still not too late to enter some of the many side tournaments running alongside the main event.
