I've just released a new version of my engine.

The changes:
Support for chess960
More aggressive LMP
Evaluate Queen pins
Evaluate Castle rights
Improved quiets move ordering
More SEE pruning
Singular extension
Improved parallel search

It should be about 50 elo stronger than 1.7
I have to thank Marco Belli for the perft unit test that I have used to check the engine.

It should be about 50 elo stronger than 1.7. How do I know? Via one of my secret weapons: reading carefully.

Fabio said in his post that it is about 50 elo stronger than version 1.7
So just add 50 to the values for 1.7 shown here at CCRL

Hi,

Thanks for the new version however the armv7 version does not run on the Raspberry Pi:

As you can see Pedone_armv7 exists and has been made executable

Al@RPi3b+:~/Pedone_1.8 $ ls
logo.bmp Pedone_linux Pedone_linux_nopopcnt Pedone_win.exe
Pedone_armv7 Pedone_linux32 Pedone_win32.exe Pedone_win_nopopcnt.exe
Pedone_armv8 Pedone_linux_bmi2 Pedone_win_bmi2.exe ReadMe.txt

Al@RPi3b+:~/Pedone_1.8 $ ./Pedone_armv8
-bash: ./Pedone_armv8: cannot execute binary file: Exec format error
Al@RPi3b+:~/Pedone_1.8 $ ./Pedone_armv7
-bash: ./Pedone_armv7: No such file or directory

As expected the armv8 cannot be executed as it's the wrong format ....
but the armv7 is not recognised although it’s there?

Thanks,

Al.

Nice progress. Every chess engine must have to do an android binary because there are many android users and they want it.thanks for the android binary.

The armv7 and armv8 executables are for android.
