I saw that video too long time ago (a friend of mine have the complete collection!) and Roman only said that because he chooses some variations where that structure happens like the dubious Qc2 Nc6 in the Nimzo and Roman chooses some variations of the Rubinstein e3 with similar structure themes and only because of that Roman said that , but that is not enough to say that Bogo is the most closer with ideas to the Nimzo, because that is not true. I am not talking only about one or two variations like Roman! Do you know who was Nimzowitsch? What are is principles of play? By the way, check the classification of Roman videos quality in Chesscafe and you will see that this videos or dvd´s are very poor in quality (Carsten Hansen- Checkpoint) and buy a good book like Starting out the Queen´s Indian by Emms and you could read there on page 5:
Quote:1.d4 Nf6 2.c4 e6 fighting for control of d5 and allowing the f8 bishop to develop. At this point White has quite an important decision to make. The most direct move is 3.Nc3, threatening e2-e4. However, Black can than continue Nimzowitsch´s ideal of controling the centre with pieces by playing 3...Bb4!, leading to the very popular Nimzo-Indian Defence. If White, wishes to avoid this possibility one move that comes to mind is 3.Nf3 developing the other knight. Black now as quite a few options: he can still play 3...Bb4+ (Bogo-Indian); he can also return to the classical paths with 3...d5 Queen´s Gambit Declined). However, the move I´am focusing on this book is 3...b6! , the Queen´s Indian Defence. It´s this move that is most in line with Nimzowitsch´s principle: after Black fianchettoes with ...Bb7 this bishop is perfectly placed to control the important central squares d5 and e4. - John Emms
Who do you believe now? Roman or Emms?
Bogo can be a little brother of the Nimzo, but the great brother is the Queen´s Indian in terms of themes and ideas. Pressure on c4 ideas, controlling the centre from a distance etc. Just ask any strong player this question and he will tell you that the closest in spirit to the Nimzo and the most respected is the Queen´s Indian.
And another thing, don´t trust anything you read or watch, because sometimes they try to sell you a bunch of easy (and sometimes dubious) ways to play. I am not coming here to sell lies or to make money, I just gave you my opinion as a player and you can believe in what you want. The important thing about reading a book or watching a dvd is not to accept everything with blidness, but to accept or decline some views and form your own ideas.
