Stockfish 2.2.1 vs IvanHoe B46a
I found the rar file for this Ivanhoe version in a folder I had forgotten about. In hindsight I wish I hadn't, because it causes me more work. PeterPan leaves 3 calling cards in his compiles: the uppercase "B" in B46a- which is there, his name when you run the exe, which is not there, and the name spelled "Ivanhoe - which is not there. He just doesn't use the spelling "IvanHoe". And that includes the spelling when the engine is loaded. Now I have to run this down and find out where this version originated. At any rate, here are the "you decide if it is reliable" results:
1CPU/32bit
128MB hash
Bases=NONE
Ponder_Learning=OFF
Perfect 12.32 book w/12-move limit
40/3 Repeating
Match=50 games
Stockfish 2.2.1........+63.........+17/-8/=25........59.00%.......29.5/50
IvanHoe B46a..........-63.........+8/-17/=25........41.00%.......20.5/50
Losing a match by 1 game to Critter (which was a 2 game loss until I found a time loss by Stockfish in a "probably" drawn position- which when replayed was, in fact, a draw) and then this effort- 2 damn fine efforts back-to-back by Stockfish 2.2.1
I shall now rest,
