Alan Lasser's Game of the Week

   The scariest chess monster this Halloween was this pawn blob seen at the European Team Championships;  the winner sacrificed the exchange just to unleash the loathsome beast.  The mighty pawn blob soon dominated the position, tying up the Black rooks and blockading the Black king.
