Phalanx XXIII

After long fourteen years and nine months, a new version of Phalanx is available from
https://sourceforge.net/projects/phalan ... n%20XXIII/
Changes are:
- Xboard protocol version 2 compatibility, including the periodic updates feature
- New -n commandline option to limit nodes per second
- New -z commandline option to randomize root moves within a given centipawns margin, e.g. phalanx -z 40 adds pseudorandom values between -20 and 20.
- Easy levels now don't play instantly, but use time
- Bugfixes
This version retains the style, strengths and weaknesses of the original XXII released 2000-01-16, it should be a bit stronger with the bugfixes, but there are no modern search techniques introduced, yet. This was like working on a vintage car, you never start with adding a turbo, first of all it needs to be fixed and polished
Enjoy

Thx a lot Dusan.

Why use command-line options for features for which XBoard protocol has standard commands (
nps and
random)? That doesn't seem very user-friendly.

EngMan.exe? What's that?
I guess it must be not as WinBoard-compatible as you think. You should not have such problems if you use WinBoard to install the engine...

Hello Mike,
Please browse to the engine to install it.
Engine > Load First Engine
EngMan is no longer required.
Later.

Well, so claiming that it has "XBoard protocol v2 compatibility" seems an over-statement. It seems most of XBoard protocol would not work, (i.e. is ignored), and you have to use command-line options in stead.
