I the meantime I checked some positions in the TB's and saw that even the ones where Black has a positional advantage are won for White if there isn't a forced capture or a stalemate. e.g. [D]N6N/8/8/4k3/8/8/8/K6N w - - dm 20; (Black to move draws because of capturing a knight) or [D]8/8/5k2/8/8/8/NK6/NN6 w - - dm 17; Because the win is not easy to find by search but not impossible, I think I will use an value between +2 and +4 [pawns] for this kind of positions.
