Surely the easy solution to find winning chances is 4. Bd2 c5, very unbalancing, sound, and interesting.  Now what to play against 4.Nbd2?  That's the real question...

I agree with MrCookie. It's hard to play for a win with Bogo-Indian. One of my recent correspondent games went like this:


And yet, I agree with Gilchrist is a legend. In an OTB game the better player has to refuse the draw offers trying to outplay his opponent even in the equal endgames. Although the question is: "Why I have to play such an opening and then try to outplay my opponent in an equal endgame?.. Why not playing KID, or Modern Benoni, or even QID where chances to outplay your opponent are way better?".. 

1600 players might have some trouble if you vary with the snake-benoni.. d4 Nf6 c4 e6 Nf3 c5 d5 exd cxd Ld6. Then study among others the games of Gashimov and Miezis.

I've played the bogo-indian for years with good results. 
My problem is playing lower rated players, its damn hard to win! I've got OK positions even against GM in the bogo, so I really like the defense and would never give it up.

I follow the chess openings for black explained repertoire, and the lines recommended can end up in drawish positions even 1600 players easily can hold.

I'm now looking for alternatives to 4...Qe7 in the main-line. I've looked at 4...a5, but still its very drawish.

Also been looking at this funny move order 1.d4 Nf6 2. c4 e6 3. Nf3 Nc6, just to mess things up a little, and maybe go into a kings indian kind of positions instead.

What do you other bogo-indian players have to recommend? To play for the whole point, 4...Qe7 is almost out of the question in my opinion.
