Three summers ago, I was invited to the Swedish city of Eskilstuna, for a brief but exciting match against their top player, the affable Nils Grandelius. Earlier this month, Grandelius visited London, this time to play a match against my England team-mate David Howell. The England-Sweden Challenge match was staged as part of the 30th anniversary celebrations of the founding of the London Chess Centre and the relaunch of Chess magazine.
