This is true for non-PV nodes, but not for PV nodes. Try to measure the relative frequency of the first, second, third (...) move being the best at PV nodes. Unless you are much better than me, the result will be rather depressing. The last time I measured, the first move was the best only about 65% of the time (IIRC). It was quite common that the best move occurred near the end of the move list.


Isn't this inherent in the chess game, where the best move is often not what you expect?

I mean, normal move ordering heuristics are fine for the junk part of the tree but PV nodes typically require a real good move.
