Spain put up an excellent performance in coming in a good second to Holland in the Clare Benedict tournament ; this result was due to two players— Medina, 5 out of 5 on board 4 and Diez del Corral, 4 out of 5 on board 2. Del Corral is a formidable and

adventurous attacking player—even in good form such a player always stands to fail sometimes ; here is the 'one that got away' in the Clare Benedict.
