I've always played 3.e4 against the QGA, and I think this is one of the better parts of Ward's book. Also, I've always played the sneaky 1.d4 d5 2.c4 c6 3.Nc3 Nf6 4.e3 against the Slav, and I think it's just as good as anything else. Unfortunately, I think Ward could have given us more coverage in these lines, especially against 4...a6 and even 4...Bf5?!, which is supposed to be bad for Black but played very often at club level.
After 1.d4 d5 2.c4 c6 3.Nc3 Nf6 4.e3 a6 5.Nf3, he makes no mention of 5...Bf5 (only looking at 5...b5). Maybe 5...Bf5 is dubious, but a quick database search didn't reveal a consensus as to how White should best continue.
His coverage of 4...g6 is a little thin as well, and he kind of glosses over 1.d4 d5 2.c4 c6 3.Nc3 dc 4.e4 e5, not even mentioning 5.Nf3 ed, which is too bad, because I was hoping to get his opinion on the piece sac 6.Bxc4 dc 7.Bxf7+. I assume Ward wants White to play 6.Qxd4 (or maybe 6.Nxd4)?? Who knows though, because he doesn't mention this move order as far as I can see.
Overall I guess I agree with Carsten Hansen's review (
http://www.chesscafe.com/hansen/hansen.htm); in fact, I think it's exactly on the money. Which is too bad, because I've liked some of Ward's books and had really hoped for more from this one given the higher quality of the other books in this
Play the... series. However, if you, like me, play these lines as White anyway, you'll probably want the book.
