King Solomon's position, again (Andscacs & Houdini)

[Nordlandia]

I can't manage to find the opening move resulting in that position. I can however reach a very similar position

Black Q-Knight is present here. Help to find the opening resulting with the white-squared bishop present for black.

Chessmaster XI

Chessmaster vs Kasparov personality

Because of the limitation of the software (CM XI is soon 12 years old) each player can only allocate 3 cores. So with ponder enabled my machine is under 75% load.

TC was 30m+30s + ponder enabled.

Kasparov personality is somewhat weaker than Chessmaster.

Norlandia,
It looks like the 2003 book you reference may have gotten it wrong. Stockfish thinks FEN#6 is a win for white:

#6: According an gambit endgame book from 2003, this position was believed to be in equilibrium, recent analysis say otherwise.
