If there is no piece that pseudoattack the king from all directions then it means that the only possible checks are based on the to square. I already do it when I update my pin arrays but I did not think about it when I generated my function to detect checks in the first plies of the qsearch. Note that my pin array can also be optimized. Today movei knows only the pinned pieces of the side to move and I believe that it is better to know the pinned pieces of both sides and to update them. Uri
