Fix critical SEE bug It is somewhat unbilievable but our SEE is broken ! If the first SEE move is a king capture and square is defended then SEE continues instead of breaking. The bug shows only on normal SEE, not see_sign() so probing with a: dbg_hit_on_c(slIndex==1, captured == KING); reports just a tiny: Total 3465656 Hits 6646 hit rate (%) 0 Bug was there since 351ef5c85b6d4b9c71e9da of 26/6/2011 (!) although for some reason didn't show immediately, indeed the bougous patch was a "No functional change" (!!) bench: 4793754
