Chess Tiger is nearly the perfect program to do battle against humans and
computers (IMO).  Hardly any weaknesses, very strong in endgames, tough to beat
even using anti-computer tactics.

"ChessTiger 13 was the first amateur program that entered of the swedish
SSDF-list from nowhere right to the top. So the expectations to its successor
are high of course. No problem, ChessTiger fulfills them all. The well- balanced
and safe (also tactical: I cannot remember even one game in which ChessTiger was
crushed by tactics) middlegame play build the base for the successful endgame.
In endgames ChessTiger is almost unbeatable and is also ahead of Shredder which
is said to be the strongest endgame player. I disagree, ChessTiger is stronger.
A typical game with ChessTiger goes as follows: opening, solid middlegame, and
in the endgame Tige shows his claws. If the opponent is able to defend perfectly
and does not make any mistake, the game edns in a draw, otherwise ChessTiger
wins. Impressive. Absolutely reference, which might be equalized by the new
Shredder 5.32, but for proof there is more testing necessary."

Chess Tiger 15 is even better, as shown by ChessFun.

However, of all the engines in existence, only Junior 7 seems to pose some
unique problems to Tiger.  Perhaps Junior's programming specifically beats a
gray area in the Tiger Algorithm.
