Chess: How does Black win?

ANOTHER round, and yet another former Scottish champion bites the dust at the 118th Scottish Championship at the LifeCare Centre in Stockbridge, Edinburgh – one from the same household, top seed and local favourite, GM Ketevan Arakhamia-Grant!

Keti, the only grandmaster in the field, lost a highly entertaining struggle to Clement Sreeves, one of Scotland's leading junior players.

Sreeves, 20, managed to safely navigate his way through the complications to reach the key position near the end of the game in today's diagram, where he found the correct winning plan with 56 ..c4! 57 e6 Rg2+ 58 Kd1 fxe6 59 f7 Rf2 60 g5 d3 61 cxd3 b3! 62 Ke1 Rxf7! 0-1

Up against such a highly rated grandmaster, Sreeves' win – which has to be the biggest scalp of his career – proved not only to be a popular one, but also one that was well deserved. Sreeves and Paul Robertson are the only two players now on a perfect score of 3/3, to meet in a round four showdown.

The shock win by Sreeves over the top seed sensationally throws the Scottish championship wide-open in the chase for the historic title first claimed in 1884 by John Crum (1842-1922). There are another six rounds to go though, and with Arakhamia-Grant and IM Craig Pritchett now chasing the leaders, we're set for an exciting finish.

Standings: 1-2. C Sreeves and P Roberts, 3/3; 3-7. IM C Pritchett, C James, H Olsen, A Dempsey and A Green, 2.5.
