Can you do this test ?

[tibono]

Hi all,
I am reading without understanding much from this thread, I am puzzled... Can somebody kindly tell me what the objective of these tests is?
Eventually, is there a useful conclusion as an outcome?
Thanks!

In training mode, the engine has to try even the bad moves in order to learn :

In tourney mode, the engine respects its EXP file as much as possible :

Why did the game end so quickly? Because in chessbase when I accidentally turn the mouse wheel the engines stop playing so I decided to predict the victory myself (you can see from the engines' evaluation that the victory goes to white's advantage)

Hi, thanks for the feedback. I did see this post but it didn't look that conclusive to my understanding: different settings provide different behaviors, yes I can see that. So what? It was to be expected.

Oh, I think I see your point now: test1a settings shouldn't be used for serious games, correct?

What are your results for test 1 ?

I didn't run the test, I didn't want to install a new engine just for that. Nonetheless interested, for my understanding... thanks again.

Exactly !

No problem, other members were kind enough to do the tests to better enlighten the chess community.
There was no need to install anything, just run the downloaded engine...
