but the program (gambit-tiger1) sees that the attack is unsound. it only
plays attacks that are not unsound. or nearly not unsound. :-))
it has the same strength in tactics than rebel-tiger13 has,
and the same search depth.
so it will play a very clever move, not a very easy unsound and bad move.
the move is nearly sound. only when you search deeper than gambit-tiger,
you maybe see that it is not sound. but since few programs search that deep,
they cannot refute the moves.

that is the trick.
bring your opponent into critical decision situations, and the plan behind the
move should be deeper than the horizont of your opponent.

right.
it must be something.
therefore you need special knowledge and special search-extension methods.

right. and it plays stronger than rebel-tiger13 IMO although the engines are
very similar.
