For eval testing : using mirrored fen's are useful. Also , in case you want to find out uninitialised arrays/variables , etc : test bettwen debug and release versions - the node count , pv , stats (like cutoff rates , etc) should be identical. Also , if you support multiple platform , test between platforms and ensure that the output remains the same for same search parameters. Using a boundschecker helps to indentify obvious bounds bugs. If your program is parallel - becomes more complicated ... Hope this helps, Mridul
