Hi,

if (r_beta == 4,75) and the real score is 10,00 the fail-soft score can be
anything between 4,75 and 10,00.

Any returned value >= beta will immediately result in a cutoff and return the
current best score. The alphabeta algorithm will not check if there are other
moves with higher score.

Thus in your example at some ply there is a move tried first that returned 4,75
and the best move which would return 10,00 is never checked.

Greetings Volker
