Bests & Worsts Reviews from Amazon

Regrettably, MCO 15 is not what it should be. First, like MCO 14, there are countless typographical errors. Experienced players will no doubt suffer through this, but the editors are the ones who should have suffered so that readers do not have to. Secondly, most of the material is in lifted from MCO 14. Mr. De Firmian has his favorite openings and updates those better, but for non-topical lines developments go unmentioned. Thirdly, in spite of the claim that variations have been checked by computers, I have found serval cases where computer evaluations refute those given. So while computers must have been involved in the production of the volume, it would be interesting to know what percentage of the lines were actually checked. For an author who is sensitive enough to never fail to use the he/she convention, perhaps more thought could have been given to the environmental impact that this book would have given its limited use. More could be said, but I think that this suffices for those who are looking to spend thier money wisely.
