I can only imagine you are referring to where they cover Prie's analysis in CBM 106? After his recommended 15...Qe5 16.Bc3 Qc7 17.Kb1 (or 16.Kb1 Qc7 17.Bc3) 17...f6, 18.Rhg1 has scored 100% for White in three games (one with Prie himself playing the black pieces and two with IM John Bartholomew, a player I am quite familiar with who lives a few hours away from me) and looks like White has quite a nice position. The games all continued 18...Nc5 19.Rxd8 Kxd8 20.Bd4 where both 20...Bd6(both Bartholomew games) and 20...Kc8 have been tried. The Prie game continued 21.Qc4 Qxh2?? and White was winning already after 22.Rd1. An improvement could be 21...a6 but even there White looks to be better e.g. 22.Rd1 Kb8 23.c3 Be7 24.Bc2 with the threat of 25.b4. Any holes in my analysis you might be able to point out would be greatly appreciated since I play this line as White.
And after 20...Bd6, the line which was played in both games 21.Bxc5 Bxc5 22.Qc4 looks to be drawish to me, while certainly Black has no chance to win the game I also don't see why he should lose. I don't know if White has real chances to win in this line despite the 100% score. It seems at some point White will be forced to capture on c5 leading to some form of endgame with opposite colored Bishops. Maybe 21.f4!? is an idea trying to preserve the light-squared bishop?
pfren, what are your thoughts on these lines?
