The 0.42 version also supports UCI. Leila is Windows successor of a DOS program PC-Chess, which already participated in the "Historic" First Italian Computer Chess Tournamenst held privately in 1999 by Gianluigi Masciulli.

=Tournament Play= As mentioned, Leila won the CIPS 2001, was runner-up behind Delfi at CIPS 2002 and CIPS 2003 and played in total five CIPS and three Chess Computer Cups. She further participated at the CCT4 with a 50% score.
