In general i think one should try moves that change score drastically.
Capturing a piece is of course changing score drastically, but for me
there are many other moves too. Like if my queen was attacked sometimes
that caused for some reasons big score. Like 3 pawns difference in
playing or not playing it. So in that case i do such moves too!
