Score against Version 18: 64% (+100 Elo)

moveordering refactored and considers “defended by a pawn” for own pieces
if depth2go>=4 and no hashmove is available, a shallow search is used to find the most promising move
beta-pruning at depth2go=1,2,3 with margins 0cp, 250cp and 500cp
4 captures extend the search by 2 ply
repetition detection: if a position occures twice in the search tree, it is evaluated as drawn
