The **CSVN 45th Programmers Tournament**, superseding the Dutch Open Computer Chess Championship and the International CSVN Tournament, took place at November 30 and December 01, 2013, [|Denksportcentrum] [|Leiden].

Twelve programs participated, operated by their respective authors, including the brand new Deep Fritz by Gyula Horváth, and Shredder by Stefan Meyer-Kahlen. Jonny by Johannes Zwanzger, which played the WCCC 2013 on 2400 cores of the btrzx3 cluster of the [|University of Bayreuth], used "only" 216 cores but nevertheless won the tournament a half point ahead of its commercial rivals.
