It scored 45.6% with 470 wins, 646 losses and 884 draws against the top 20 strongest chess engines in the 100 rounds gauntlet tournament. Ivanhoe 1945a beat 7 strong engines including Rybka 4.1, Robbolito 0.21Q and Bouquet, but lost to the 13 stronger chess engines. It also beat Ivanhoe 46h by insignificant margin but was not able to displace because of higher overall ELO rating.
Ivanhoe 1945a was derived from Ivanhoe 999946h, the last active version circulating in the Internet which was released last December 11, 2011. There were half-hearted releases in between but never became popular probably because there was no executable that came with it. The author/s assumed that somebody will compile it for them. Ivanhoes stagnated and was the weakest in the Ippolit family being overshadowed by Fire, Robbolito and even Igorrit. It is a crippled open source chess engine that will never compile unless some missing codes were inserted.
Ivanhoe 1945a is a corrected version of Ivanhoe 999946h where some missing source codes were added that makes compilation easier. Any interested person that wants to study Ivanhoe is wise to start with Ivanhoe 1945a.
