Abstract/Summary

This is a report of the 'TCEC Cup 3' computational experiment, the 3rd TCEC knockout event and the second major part of TCEC’s 15th season. It featured the best 32 engines of the ‘TCEC 15’ league event and the games were held at Blitz tempo. The different format called for different optimal settings in the engines, thereby enabling a comparison with performance at slower tempi. LEELA CHESS ZERO retained the TCEC Cup, defeating STOCKFISH this time. All decisive games in the supplementary data have been played out by FRITZ17 at search depth 24 to enable and benchmark endgame practice.
