From: Mark Schreiber hotmail com> Date: 26 mar 2007 Subject: RE: Watanabe's comments (2) Watanabe was surprised by some of the computer moves. Sometimes he underestimated Bonanza. Sometimes he overestimated Bonanza. There should be more computer vs pro games so we can get a better understanding how well the computer plays. Before the game Watanabe rated Bonanza about 2-3 kyu Shoreikai at 2 hour games. Did Watanabe rate Bonanza after this game?
