L'Ami's Lasso at the Unive Open 2012

The final round of the open tournament was extremely exciting. Frizo Nijboer was on 7.0/8, a full point ahead of four Dutch GMs: Erwin L'Ami, Sipke Ernst, Robin van Kampen and Jan Timman, with 6.0/8 points each. Three of them drew their games after long fights. The fourth pursuer, Erwin L'Ami, produced an epic battle in which he finally ground down Nijboer with the black pieces.

... Erwin wins it and joins Frizo in first place

Brynell's Burners

When the bishop does not control the corner square of a rook's pawn often difficult problems arise:

Timman's Timing

Pure bishop endings have a large drawish tendency:
