Am wondering if anyone can recommend a good book (or books) on the Bogo-Indian and Nimzo-Indian for me to possibly buy. I have limited experience with both, but seem to be well enough able to play a good opening with it in some areas so I would probably eschew a beginner level book, while also preferring to avoid something too variation-heavy that doesn't explain outlines and plans. Perhaps for practical purposes we could say I have a performance knowledge in these openings that comes to maybe 130 on the low side, disregarding my usual strengths.
I've never touched the Queen's Indian in my life, but I daresay that looking through GM games I could get to the same level as above (and I intend to look through a good deal of Bogo/Nimzo games through history to better acquaint myself as well), so if anyone has a particular recommendation for a good book in this as well; do please say.
