Ready for a surprise?
The Baron 1.4.0 selects Rg6 for the first time in 1:48 on a P4-2.4. It changes
to Qe3 after 2:46, and finds Rg6 again after 3:59. So in order to win the bet I
only need to find a faster computer :-). Baron doesn't see a win. But well, that
wasn't part of the bet, was it?
Richard.
