Hi all,
LittleThought 1.05 available for download at http://www.kimiensoftware.com/littletho ... hought.php
It should be significantly stronger than 1.04:
- @ 1s + 0.1s = +170 elo
- @ 10s + 1s = +110 elo
- @ 60s + 1s = +60 elo
Major changes:
- Added Chess960 support
- Rewrote SMP so it actually works now
- Removed several eval features which were hurting it
Cheers,
- Nathan Thom

Re: LittleThought v1.05 released
Unfortunately there are some problems with the Chess960 support, the (long?) castling moves are sometimes not accepted, see example below: g1e1 is the castling move (KxR) and in the internal board it is ignored.
I used LittleThought with Polyglot under Arena.
Best wishes,
Alex

Re: LittleThought v1.05 released
Whoops, there's some nasty Chess960 bugs in there... better off leaving that feature alone for now. I will try to rush out a fix for them.
The standard variant is unaffected and should still run fine.

I believe I've fixed all the Chess960 bugs, and have uploaded v1.051 at http://www.kimiensoftware.com/littletho ... hought.php
There are no changes to the standard variant.
