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).  Author: Chris Bolt  Rating CEDR=2478 v.2.26 This release works around an issue whereby the move returned in the UCI best move command could be different than the computed principal variation. That is always bad, sometimes awfully bad. The defect seems to be most prevalent at longer time controls, it is possible its impact is fairly neglible in bullet and faster blitz time controls. To install Eubos as an engine in Arena: 1. Select Engines > Install New Engine 2. In the file browser dialog that appears, change the drop down to *.bat 3. Navigate to the Eubos binary location, select the Eubos.bat 4. Select UCI p...
