Fritz 21

[Werewolf]

So an engine that's 30-40 Elo stronger. Are there any new GUI features?

[Paloma]

I really don't like the 'ChessBase Product Installer'. I sent them an email to send me the offline installers (download links) so I can copy them to USB etc. We'll see how that goes.

You can select to keep the installation files after the download during installation.

I found an alternate way of getting those files.

Hi Jason, you have a PM

So an engine that's 30-40 Elo stronger. Are there any new GUI features?

The style- opponents are animated now

And advertising says style of simulated masters is even more authentic than it was, tried only very little of that kind till now (not even 500 games to let Frank this time know in the first place, it's one more time nothing, at least for him and me ). All I can say so far: it's fun to see Tal in video laugh and cry about the moves on the board, regards

[Frank Quisinsky]

Hi there,

I wrote to the style in a message before:
"Maybe a bit to many to fast draw games"

Seems to be nonsense.
Draw stats are really strong after now around 750 games.

Furthermore, no double-pawn problems I saw now in games after.
For better stats I have indeed not enough games with 1.300 only.

The quick win stat. seems to be light better.
Move average is only 1 move higher as from Fritz 20 251024 (Gingko).

In my testing around +15 Elo to Fritz 20 251024 (Gingko).

So I am thinking could be a really a nice update.
More aggression once again, that's good!!

4 games lost after 750 games.
One game vs. Smarthink?? Must be looking later in detail!

Best
Frank

[Frank Quisinsky]

What is here the problem?
Lost vs. SmarThink is for a TOP-20 engines not really to explain!

What is here the problem?

43...Bxd4? indeed seems a little spooky.
Not only doesn't F21 ponder about this one move started with empty hash as long as I was watching it's output single thread, nor doesn't any other engine I tried so far from old to new ones, only exeption I saw so far was ProDeo 3.0, but also only for a few seconds, regards

[Tibono]

Move average is only 1 move higher as from Fritz 20 251024 (Gingko).
In my testing around +15 Elo to Fritz 20 251024 (Gingko).

Hi Frank,
Ginkgo, please, if I may point this out

Hi Eric,

thats really bad, not good ... so many parts of site I have to change.
The database also ...

This need some years ...
I will start soon!

MIST

Please, give the information to no others here.
To embarrassing for me.
