That sounds promising - where is the new venue for the Metropolitan congress? I looked in vain for it (and even my own events) on the new ECF calendarIn terms of good London tournaments, I'd add both Metropolitan and Ilford to the list. Thew new venue for the Metropolitan places it in a fantastic location right on the River Thames, and the playing hall is excellent. The only downside is the rather cold and bleak analysis room/cafe, but the compensation of being able to pop over to Tate Modern for an hour is great.
PS looking wider afield, there are loads of great tournaments; Kidlington is my favourite, with St Albans, Noteboom (Leiden NL), Brentwood and Kilkenny (IRL) close behind. I recommend players based in London look at tournaments in Belgium and Paris and even The Netherlands as they are very easy to get to by Eurostar, and you would not be amazed to hear that there is an interesting comparison to be made with English events (not yet played in a Scottish or Welsh Congress). Not necessarily better.
