Is this game in progress now, with BB+ as black?

I am curious to hear from kinliveson why he chose this starting position.
I just found that this line is in Jiri Dufek's book which, I think, came with Rybka 4. It seems to have been played hunreds of times - I strongly suspect not one of them by humans. (Frankly speaking, none of white's moves up to here makes much sense - no offense intended.)

Kappatoo, hi, the position is chosen for testing engines' understanding of openings. My belief is the position is draw after many many games. It is one of a few difficult positions in my testsuite. The challenge is still open; I will play White.

Hi kingliveson,

sorry for spelling your name wrong.
I agree that it's most likely still in the draw range; I nevertheless believe this is better for black.

Okay, if the challenge is still open, then I accept it. 5...Nxe5.

I will be using IvanHoe, Critter, and Komodo.

Tough decision. 6...c5 was also tempting, but I play 6...Bd6.

I will use Tianhe 1-A. Okay, maybe also Houdini 1.5 and Rybka 4.
