Season 1 Round 4 Heat 1

This was supposed to be a double-round but I had to restart it because I selected the wrong version of Ethereal. And on the restart, forgot to make it a double round. Curiously, when I stopped it, Stockfish had a less-than-perfect score. So on the one hand, it had some losses or draws, and on the other hand, at least the engines are not simply playing the same game over and over. I will check the end boards when all is done and look for duplicates. So far there have not been any.

Anyway, here’s the results.

Engine               Win     Draw    Lose
Ethereal 20191110    1 [1/0] 3 [1/2] 2 [1/1]
stockfish 111119 64  6 [3/3] 0 [0/0] 0 [0/0]
Defenchess_2.2       0 [0/0] 2 [2/0] 4 [1/3]
xiphos-0.6-linux-sse 1 [1/0] 3 [1/2] 2 [1/1]
