After five rounds of the Owens Corning International in Wrexham, the surprising leader is the Swedish International Master Christa Hartman, who is one of the lowest-ranked contestants. He has 31/2 points, half a point ahead of James Howell and the veteran Hungarian grandmaster Isztvan Csom.

Most recently, it has been the super-veteran David Bronstein who has been having most fun. After a slow start of two draws and a loss, he was jolted back to life when the German master Alex Jeffe played an archaic line of the King's Gambit against him in round four.

One of the great King's Gambiteers himself, Bronstein entered into the spirit of it, producing a game with a true flavour of the last century. Even the end of the game contributed to its general air of ramshackle originality. When Bronstein allowed his opponent to repeat moves and force a draw, he could have won with 29...Ke8. White has no good check with his rook, and 30.Nf4 is adequately met by 30...Nd6.
