How much stronger ?

[Richard Vida]

Recent changes/additions:

- Automatic detection of SEE4.1 capable CPU. Both SSE4/non-SSE4 codepaths are now compiled in a single executable and chosen dynamically at runtime.

- Large pages suppport. This requires sufficient user privileges and right OS settings.

- Own book is automatically turned off when analysing.

- Engine now honors multi-pv even when the root position is a tablebase hit

- Session file now supports IDEA. SF writes are disabled at root when any moves were excluded.

- Session file writes are now protected by OS IPC mechanisms (semaphores/mutexes). Same session file can be accessed concurrenlty by multiple engine isntances without risking corruption (useful when running IDEA)

- Removed UCI option "SF strategy", now its value is hardwired to "depth"

- New UCI option "SF move limit" which disables learning after game has reached given number of moves. When set to 0 this option is ignored.

- New UCI option "SF material limit" (0..32). Disables learning when total amount of material is less than the given amount [Q=6, R=3, B&N=1]. When set to 0 this option is ignored.

- Gameplay related changes:
* Tweaked blocked-pawn recognizer
* Skewer detection in eval
* King safety tweaks
* Pseudo-contempt: slightly increased preference of moves increasing pressure on the opponents king
* slightly increased preference of pawn pushes in semi-blocked positions
* Recognizing more types of drawish endgames

- new console mode commands "sf probe", "sf delete", "sf store" for mainpulating session file entries

Running the 64-bit Linux compile in Scid causes termination when tablebases are accessed.

I don't know if this is the same problem that affected the previous Critter: http://www.mail-archive.com/scid-users@lists.sourceforge.net/msg05894.html
