RE: CZ Phoenix attack
Thanks! I should definitely update our database soon...I just haven't made the time with my other book projects. I really appreciate your games, though!

RE: CZ Phoenix attack
I've only made it through the first 25 moves or so, but this is really good play.
Do you think this 9...h6 deserves a line in my book? It isn't awful, but I think it's pretty clear once that move comes down that Black is not going to get equality any time soon. Still, some guidance for White is probably appropriate.

RE: CZ Phoenix attack
Yes, I think that 9.h6?! is inferior to all three alternatives (9.Qe7, 9.b6 and 9.a6) that you have analysed, and it does not contain any distinctive ideas for Black. So a short footnote should be enough.
BTW: I found another corr game where 9.h6 was played. There Black reached equality after 11 c4?!, so I think it is definitely better to prepare c4 by 11 Nbd2.

RE: CZ Phoenix attack
I consider the following game my best game with the Phoenix attack so far, and it is also theoretically important. My attacking maneuvre 20.h3, 21.Nh2, 22.Ng4 is nonstandard, I have never seen this before in comparable positions.

RE: CZ Phoenix attack
Great! maybe I can post some of these in a later book.....probably much later...I'm so far behind! I was hoping to get either the followup to Zuke'Em or the CK Phoenix book done by Christmas, but that does not appear to be in the cards.
I will, however, have a very nice set of science books out sometime soon....you can blame them for the delay.
