Pro Deo 1.1 Vulcan {9i8i} 'Ripley' settings play 1..Qf5 after 24.4 seconds. The
score is positive for Black, to about 1.1 pawns, where Chessmaster evaluates the
position as negative. That probably does not mean all that much here. Maybe if
it was negative for Black, Pro Deo would have been lees inclined to exchange
Queens.
But, a more important observation from a testing point of view:
Pro deo default is much faster in reaching a plydepth of 15 or more. Pro Deo
'Ripley'has lots of checks in Q-Search and only 4 plies selective depth in
midgame ([Adjusted Selectivity MIDG = 4]). So, dilemma, which is better? Or does
this just not work?
