At 17 ply DIEP finally sees white is winning here. Incredible!
Pawn less in a nearly closed position and winning by a "here goes my
knight" move.

339M nodes +0.49  PV 17 ply is now the first 16 plies of the above
variation. The plies after that probably fell away because of
hash overwrites.

This is my first test at home with 200MB hash and i like it!

At WMCC i will play with a bit less hash as i lose 20mb memory for tables
to 5 men then. 180mb or so hash then, still not bad!
