For awhile now I've been trying to find an alternative to the Benko Gambit vs. 1.d4. The Benko is by far my favorite opening vs. d4 but the problem with it is it's so easy for white to avoid. For example, white can just play 2.Nf3 or after 1.d4 Nf6 2.c4 c5 he can play 3.Nf3 (or 3.e3). For the past few months I've been trying to find another opening that I enjoy playing as much as the Benko and can be played against different move orders.
First I tried the semi-slav structures, but after facing 2 semi-slavs in 4 rounds at the Canadian Open and many others in my club I am rather turned off the slav complex as a whole. It seems EVERYONE is playing a slav of some sorts these days and so that one gets a pass.
Then I tried the Queen's Gambit Accepted as it has a similar structure to the Meran Semi-Slav which I enjoyed playing as black. Tried it for awhile but it seems like it's one of those "equalize first, counterplay later (maybe)" openings which don't really suit me. I prefer a more immediately dynamic approach a la the Benko.
I thought about the Modern Benoni and Blumenfeld Gambit but again those are very easy to avoid.
That brings me to the King's Indian. Some similarities of structure and theme with the benko, very dynamic, and can be played against practically any move order. I've ordered "Understanding the King's Indian" by Golubev and Bologan's new KID repertoire book as well. I hope this will fill the many many holes that have persisted in my black queen pawn repertoire for far too long.
