Resources on the Bogo-Indian opening I'm looking for good resources to learning the Bogo-Indian opening: 

 [FEN ""]
 1. d4 Nf6 2. c4 e6 3. Nf3 Bb4+.


For background purposes, I play at around the 1750 elo level. I like closed positions (I play the Caro-Kann &amp; Slav defence as Black, &amp; always open with 1. d4 as White). Lastly, I'm motivated to learn the Bogo-Indian because I'd like to avoid the Nimzo-Indian.

Thanks in advance!
One of my favorite chess you-tuber's - IM Christof Sielecki has written a book on it: Opening Repertoire: Nimzo and Bogo Indian http://www.amazon.com/dp/1781941092/

It would be worth to take a look at it!
