Other Most Aggressive Engine. #6

I think from testing, though I haven't tested with yours, Little Goliath NN 3.15-3.17 is the most aggressive engine by far ( and has an aggressive boosting option that drops about 4-500 elo) but it's around 3300 and is crazy sacrificial

There doesn't seem to be any Little Goliath executables for Linux that I can find, I would appreciate if you could help me find one because I would love to test it (3.15 especially is about the same strength as Patricia 2, so I could run the exact same test conditions as I did with Patricia and compare the results in a meaningful way).

Yes, Little Goliath NN plays quite aggressively, also possible Kayra Attack 1.5, Fire 9 NN. You can also remember the old engines Ruffian and Junior. If this is a human engine, it is desirable to support "go depth" commands. It really doesn’t matter 3000 or 3200, 3400 elo. 3000 This is stronger than Nakamura and Carlsen. And if it is an aggressive engine, then it is much more difficult for a person to play. The position cannot be closed.

Support for go depth and go nodes (?) is planned as of now though I'm not sure I'll remember!

But Princhess 0.16 64-bit is much calmer.

CDrill is a funny second place - looking it up it's about 1800 strength and has only played a few hundred games. Other than that it is nice to see Patricia lapping the field.

Yes of course the results are not very accurate, too few games. Well, the engines don't play until the checkmate. Now other results CDrill 1800 build 4 - 764 games. But the engine does play aggressively. The author Ferdinand Mosca tried to make it interesting for games against a person. His other engine Deuterium is much stronger.
