The final attack in the game between gm Denes Boros (rated 2439) and fm Chris Yoo (rated 2402) played yesterday in the 2018 Fall Chess Classic in St.Louis was exceptional. Violent. Gory. And just what the spectators love to see…

An excellently conducted attack by White, and one can not find any fault with Black’s play either: he simply found himself lost and could not save the game once White got h6 in.
That is the ‘thing’ about the Scilian Defence that many Black players often forget: the opening is risky and one small imprecision can be fatal.
