I've now run it to depth 14 where the output is this:
14 +0.45 1... Qg5 2. Ne2 Rxd2 3. Qxd2 fxg3 4. Qxg5 gxh2+
5. Kxh2 hxg5 6. Kg3 Be6 7. Nc3 Bf5
8. Nb5 a5 9. Nd4 g6 (506539 kN)
So, the value is 0.45 whereas the value for Ne2 was 0.25 for black. That's not a
big difference, but at least it never considers g3 seriously. I can't imagine
why DB would play that. Lousy eval, maybe. Byt lousier than Chezzz?? I don't
think so...
