Fritz: Tactical, but positionally sound. Well rounded.
Hiarcs: Positional and human-like play. Good in unbalanced positions.
Junior: Very tactical, sacrificial style play.
Rybka: Strongest chess engine. Excellent positional understanding and human-like play. Excellent evaluation of dynamic positions. Great for analysis.
Shredder: Very positional and solid. Excellent endgame play.
Zappa: Human-like play, aggressive. Very strong, catching up to Rybka.
Fruit: Well balanced positional play.

Much depends on how you tweak the parameters of the chess engine. Fritz defaults to a high contempt value while Rybka defaults to a low contempt value… which is why Fritz seems a little more tactical and Rybka a little more positional… but tweak the values and that should change. I haven’t experimented too much because I find the dichotomy useful.

If you had to rate their default playing styles from the most tactical to the most positional, how would you arrange the list of the above engines?
If that seems like a silly question, let me ask a slightly different one: which of these are the top 3 strong positional engines in increasing order? I was just wondering, that’s all, and I have no idea myself. But am very curious as to what you think.
Much thanks in advance.

Here’s my two cents worth:
In order of positional tendencies:
1. Rybka
2. Hiarcs
3. Shredder
4. Fruit
5. Fritz
