Well, the best version of the Columbus' egg is the 9b which I am using now until
the first versions of Shredder 10 will arrive...

Well, with Shredder there are only some parameters one can change, so the
changes are limited.

I agree making/changing books is so simple in Shredder classic GUI that I use
only this one as it is difficult to accept systems with are not so easy to use
when there is one so good and simple!

Well, Colubus' egg 9b prefer Qd2 too, but the evaluation is about equal and I
think it is correct.

Yes, 24...Nd5 is surely stronger than Adams move and should be a draw.
After 23.Be3 Qd8 24.Bxh6 the move Qf6!
>from Yan vs Lin 1988 seems indeed strong and refuting 23.Be3
Well, this variation would give black some advantage improving the below
variation with 27...Nd5 -0.96 19/44 (in black favor; Columbus' egg 9b) expecting
the following moves 28. Rg4 Nf6 29. Rh4 Nh5 30. b3 f6 31. Bd2 g5 32. Rg4 Nhf4
33. Bc3 Rb1 34. Qb1 Ne2+ 35. Ne2 Be4 36. Rg5 Kf7
