I guess that Bc3 played by CT is partially because CT has code that detects a trapped queen. So, after Bc3 Qxb6 CT thinks that the queen is in bad shape so it is worth losing a doubled pawn. Some time ago CT was very succesful in a position that few commercial programs (including Fritz) detected as bad, when a queen was trapped. I guess that this code backfired here, in combination with a horizon effect in which it did not see that Bc3 did not really threat the rook at a1. My program gaviota has some code to detect a trapped queen and wants to play Bc3 for while up to ply 10 when it changes to Bc5. Interestingly, Gaviota did well in that position that CT did well. I am not trying to compare my weak amateur program with tiger, I am just trying to make a correlation. I guess that this code could have created a problem in this particular position. Did I guess right Christophe? Regards, Miguel
