Knight threats on Queen We give a S(21,11) bonus for knight threats on the next moves against enemy queen. The threats are from squares which are "not strongly protected" and which may be empty, contain enemy pieces or even one of our piece at the moment (N,B,Q,R) -- hence be two-steps threats in the later case because we will have to move our piece and *then* attack the enemy queen with the knight.
