Chess engine: Eubos 2.9


Eubos
- a
 basic Java chess engine, written for kicks. Uses jcpi for the UCI protocol parts. Kind of weak, doesn't evaluate for king safety, for example. Now uses transpostion hashing, but because it runs in the Java VM on a bog standard PC, doesn't search very deeply (around 100K Nodes/s, though this is actually quite hard to evaluate due to the hashing).

v.2.9

This is the first Eubos release which incorporates a selective search. All previous releases have been Shannon type-A searches, only utilising Beta pruning

There are the usual exemptions
Tuning / Optimisation / Tweaks

Fixes
Bug fixed where, if the game length exceeded 150 moves, the DrawChecker would cause a crash
