Many thanks for the post and the pgn, in a few hours I´ll start some test with Cool Iris and new TACTICAL.

Best regards Eduard.

I'm a bit surprised about these default settings:

Random Op. Plies 16
Random Op. MultiPV 5
Random Op. Score 20

This is certainly very powerful for analysis! The fact that an engine like Eman can be defeated in Blitz games is extraordinary! I really didn't change any settings. Cool Iris played with these settings. Impressive!

In my position test, this setting is better:
Random Op. Plies 16
Random Op. MultiPV 3
Random Op. Score 20

But, what can I say if Eman is defeated with MultiPV 5?

There is othing to say, just have a great time!

Unfortunately I haven't had the time I would like, to test it against other engines, plus the change of the new PC generated me even more waste of time, you know, updating and too many etc, etc etc, by the way fritz 18 GUI is already installed.

In a few hours I will start on cutechess-cli a small tournament of four modified engines (I want to give to TACTICAL engine a different touch) plus Eman 9.80 and the latest SF development.

Let´s see how it runs.

I prefer cutechess-cli because of the concurrency.

My congratulations to you again, Anton!

The SF developers tuned the parameters on Sunday. Together with the CorChess code and the new features from Marco, the engine seems to be a bomb. Extremely good in analysis mode, and then even Eman 9.80 is defeated in the blitz, four wins in just 20 games, that's great. How are you supposed to improve an engine like this? I'm going to do some testing with the large 3072 network.

It's a bomb without a doubt!!!

On larger networks I wanted to tell you that yes, sure, it is a very good idea, it is very clear that not all users are looking for engine vs engine, go ahead and thank you so much, otherwise I will only keep up with the updates from SF.

Thanks again.
