Helen Gipson (Sco) regained the lead by beating Harshan Lamabadusuriya (Eng) 490-364, while Nigel Richards (MYS) lost 365-437 to David Webb (Eng), scoring his lowest game in this tournament so far. Helen is now 11-2 +733, Nigel is 10-3 +2166; behind them are Vincent Boyle (Sco) and Joanne Craig (AUS) at 9-4.

While analysing last round's annotated game, I noticed that Nigel had an interesting opening rack: BEQRTVY. I hand-edited the posted analysis for this turn, as I wanted to run a longer simulation. After 10,000 4-ply iterations, Quackle says that playing BEVY is about 1% better than trading BQVY in winning percentage, but more than 15 points worse in equity. Which would you play, and how long would you spend thinking about it?

TD Amy Byrne has lowered the boom on players, starting latecomers' clocks. People seem to be returning more quickly to their games now.

In the B division, Jayne MacKenzie (Eng) and Charles Micallef (MLT) win again. That's Joyce's tenth consecutive win and Charles' sixth. Joyce beat Paul Mifsud (MLT) 397-379; Charles beat Paula Docherty (Eng) 506-282.

Jayne remains one game ahead of Charles at 12 and 11 wins. Annemarie Holland (MLT) beat Catalin Caba (ROM) to remain two games back at 9 wins.
