Chexa played the [[CCC 2008]] and [[CCC 2009]] Italian Chess Computer Cups, the [[IOCSC 2010]] and [[IOCSC 2012]] Italian Open Chess Software Cups, the [[CCT15]], and won the [[IGT 2013]] of original engines.

Mauro Riccardi is in the process to find the right balance of [[Passed Pawn|passed pawn]] and [[Candidate Passed Pawn|candidate]] values, since too often Chexa has overestimated their good locations, and is about to introduce a table to evaluate [[Pawn Islands|pawn islands]] <ref>[http://www.g-sei.org/chexa/ Chexa « G 6]</ref>.
