IMO 1. the null move algorithm made it possible for OTHER programs to come deep, and maybe even deeper than genius. so they outsearched it. 2. the team of richard (especially OSSI) was not open for new ideas. 3. the way genius worked produced boring style, it computed all moves in the opponent plies, and computed a selection of only a few good branches in the own plies. this lead to a playing style where it is not always using and playing the BEST move, but it will of course not oversee threads by the opponent. by reducing the search tree genius came deep, but the asymetrical search handicapped genius when all the others came deeper due to null-move.
