Hi Tony, great to hear you are considering a sequel to your book, which I like and still use a lot! Here are some of my thoughts. Some have been addressed before, some not:
- I'd love to see a book where the opening-repertoire of volume I is 'refined'. In that sense it wouldn't be necessary to write a new repertoire-book, but just to improve suggestions and ideas in selected lines.
- I think the lines suggested in the symmetrical variation 1.c4 c5 are too harmless. Maybe mainlines with d2-d4 are an idea? Watson seems to think they are promising for white, it would be nice to hear your thoughts here.
- I also like to meet 1.c4 c6 with 2.e4, because of 2...d5 3.exd cxd 4.cxd Nf6 5.Qa4+ which I've been doing well with. The problem is that black can go 1.c4 Nf6 2.g3 c6 3.Bg2 d5 4. Nf3 when we are back to the problem of 4..dxc, which have been addressed above and in this thread:
http://www.chesspub.com/cgi-bin/yabb2/YaBB.pl?num=1082723263 - Against 1..e6 there is a similar problem after 1.Nf3 d5 2.c4 e6 3.g3 dxc4!? See this thread:
http://www.chesspub.com/cgi-bin/yabb2/YaBB.pl?num=1153817559/0 but in general I like your suggestions here.
- Maybe some suggestions against blacks solid e6,d5,c6,Nf6 setup are worth some lines.
- Against the KID your suggestion works wonders! No problem there.
- I'd like to know if you are still playing your suggested lines against the English Defence? I often feel my center crumbles with white lagging in development, but I probably haven't studied the positions properly.
- Maybe 1.c4 e5 2.g3 Nf6 3.Bg2 c6 4.d4 exd4 5.Qxd4 Na6 also should be addressed..
