Well, while I am sure that coaching-guiding two women for a competition it's not a piece of cake and congratulations for WGM Kouvatsou success. I thought that in a major event like a final game match the role of a coach should be to suggest the better choices when his student/player has the ability to play rather equal many opening ideas. I agree with your final statement but there are always preferences when you have a lot of weapons to choose for.
So...I change my question and I say what if your student ask your opinion in what to choose irrelevant from his opponent and abilitys. What you will recommend? It's the Modern Benoni defense the best suggestion?
The abovementioned move worked quite well for me so far, although I have to admit that I only tried it in rapid games on ICC yet.
Ok, Mr. Pfren let's leave the trush talk and speak the truth! If you ever had the opportunity to prepare a world championship match as a second for one of your pupils/students did you consider to suggest a Modern Benoni bunch of lines or you find that there are more favorable ideas for black against 1.d4 ? I am sure you do. I don't understand why you disagree in to something you already agree! : The Modern Benoni is a difficult pawn structure to defend.
I do the usual stuff: I do not spoonfeed them any opening, let them choose themselves, and I just provide material, and ideas. I never had the chance to prepare someone for a world title match, but I had that chance in two cases for world championship individual tournaments.
In the first case, we had no luck, and WGM Botsari finished second at the World Girls U-20 championship at Mamaia, Romania, after leading for many rounds, and finally spoiling a couple of virtually winning positions.
The other student, WGM Kouvatsou, had more luck, and won the 1999 World U-20 Championship at Yerevan- probably because I was coaching her for a rather short time, when I was living at Chania, Crete...
Her openings as white were "cutting edge": Exchange French, Alapin Sicilian, oldfashioned Italian, in general the same openings she was taught by her first coach when she was ten years old. She felt very confident about them, and I had no reason to change ANYTHING. Openings do not make you a strong player, positional understanding and tactical skill does.
