find mate (in 5) with MPV : different eval after very long think ? #17

I did another experiment with the position of Issue #11 .. indeed Bagatur v3.0 finds the Mate in 5 rather quickly ! Here's the output of SCID with mpv 1 :

Bagatur_mate_in_5_mpv_1

so, after 5.45 seconds Bagatur finds Mate in 5 ! but when setting mpv 5 SCID shows this :

Bagatur_mate_in_5_mpv_5

after 83 seconds Bagatur finds a mate : it's the Mate in 5. before that, no other Mate-in-[#] was displayed !?

the Mate in 5 occurs at depth 24, not at 32 like Bagatur v2.3 did ! -see Issue #11 but the 83 seconds seems much too long : why is the calculation / evaluation different when using a mpv like 5 ?

This is fixed now.
