I was analysing a game with Fritz 7 updated version. In this position I think
the best move is o-o-o, but Fritz did not show this move with the best 3 moves.
As soon as I played the move the evaluation for white goes up. Then I wondered
what the evaluation for o-o-o was before the move was made. So I kept pushing
"+". Fritz says there are 56 (should be 57)different moves in this position, but
when I had the first 56 moves showing, there still was no sight of o-o-o. When I
pressed "+" once more then finally Fritz sees there are 57 moves and o-o-o is
the best move.
