3.08 is not good enough

Here is movei's opinion at depth 12 on p850.

depth=12 +3.68 c8e6 f4c1 c3c2 b1b2 e6c4 b2a3 c7c5 a3b2 d8b6 b2c3 c2d1n c3d2 c4b3
g1d1 b3d1 c1d1 c5d4
Nodes: 342802724 NPS: 141594
Time: 00:40:21.01

The score at depth 11 is 3.19 and I guess the score at depth 13 may be even more
than +3.68
