Because positions where the side to move is attacking the opponents king are not stored. In a table with unbalanced material the side with stronger material is has more positions where it is attacking the opponents king. > Can we use just one >side, and if so, why even bother with the other? We could store only one side to move, and only probe when that side was the one to move, but we would have to do a lot more table probes to get the same amount of information. >And how about making "limited tb's" which only calculate from some positions, >the positions most common in actual games.
