This is a report of the 'TCEC Cup 2' computational experiment, the second TCEC knockout event and the second major part of TCEC’s 14th season. It featured the best 32 engines of the ‘TCEC 14’ 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. This event made history: the first major trophy win by a 'NN' Neural Network chess engine, LEELA CHESS ZERO, even though relatively disadvantaged by the faster tempo. All decisive games in the supplementary data have been played out by FRITZ17 at search depth 24 to benchmark endgame practice.

TCEC杯2

这是“TCEC Cup 2”计算实验的报告，第二次TCEC淘汰赛和TCEC第14个赛季的第二个主要部分。它配备了 'TCEC 14' 联赛赛事中最好的 32 个引擎，比赛以闪电战的节奏举行。不同的格式需要在引擎中进行不同的优化设置，从而可以与较慢速度下的性能进行比较。这一事件创造了历史：尽管因更快的节奏而处于相对不利的地位，但“NN”神经网络国际象棋引擎 LEELA CHESS ZERO 赢得了第一座主要奖杯。补充数据中的所有决定性比赛都由 FRITZ17 在搜索深度 24 下进行，以基准残局练习。
