This is my biggest database so far published on my site. It covers Bogo-Indian repertoire for Black against QueensIndian move order 3.Nf3, as well as Catalan move order 3.g3. In both lines my choice is Vitolinsh variation 4...c5. The arising pawnstructure after 5.Bxb4 cxb4 promises double-edged play with very unusual pawnstructure. Additionally, you'll find coverage of White tricky 3rd moves, such as 3.Bf4, 3.Bg5 and 3.a3. As always, my PGN file provides extremely detailed coverage of all major variations played on practice. After studying my file, you will settle for many years ahead!
