Não menos importante a nota que o autor menciona acerca da seletividade:

"Selectivity is another key feature in Houdini. Just like a human player, an engine doesn't look at all the moves to the same depth. Potentially good moves are examined exhaustively, whereas apparently weaker moves are only given a quick, shallow look. Some moves are examined 40 or 50 plies deep, other only five. Houdini has a good ability to identify which moves in the position have some potential. It's similar to the instinct and experience of a strong human chess player – looking at just a handful of moves in a position, discarding nearly instantaneously and without thinking the 30 other moves."

 

Fabricantes como Novag e Mephisto na década de 80/90, já tinham implementado esta característica, o que por certo derruba algumas opiniões de que o computador provocaria um ataque contra si mesmo. Sem citar nome, um GM brasileiro opinou acerca desta possibilidade.
