Komodo 13.2.5 Human is the best and most impressive Komodo personality for human sparring in my view. It is appropriately named.
Adjust the Skill level down if needed.

Komodo 11 doesn't have those settings.  Only Komodo 13.2 or greater does.

You should be able to modify the settings from any GUI using the engine settings.  With Fritz it is probably best to create a new UCI engine, choose "parameter" button when making it and set the personality to Human when you create it and save the engine with a new name so you can easily just load that version again.

Does access to the different personalities depend on the GUI?  I currently have Komodo 11 (Fritz).

The Personalities feature in the newer version (13.2) of Komodo is very interesting - this is from the readme file:

Personality

-----------


Komodo 13.2 introduces engine Personalties. These modify how Komodo plays to reflect the styles in each Personality name. The Default Personality is regular Komodo.  Note that Personalities other than Default will internally set Contempt and other parameters to reflect that playing style. The Personalities are:


Default: This is the default and strongest personality. You have full control over Contempt settings. Most of the other personalities will play roughly one skill level weaker than Default.

Aggressive: The Aggressive personality will attack relentlessly with no concern for their own safety. They prefer active pieces, and are biased toward playing with the Queen.

Defensive: The Defensive personality emphasizes king safety and a solid position above all else.

Active: The Active personality tends toward open positions and well-placed pieces. 

Positional: The Positional personality tends toward solid play, maneuvering, and more closed positions.

Endgame: The Endgame personality prefers playing through to the end to win by promoting a pawn.

Beginner: The Beginner personality doesn't understand the fundamentals of chess, especially endgame principles, and is mostly looking to check and capture. But please note that it will drop in strength between one and two levels, so you still have to set the skill level appropriately if you hope to win!

Human: The Human personality is optimized to play like and to beat strong human players, playing aggressively, avoiding pointless simplification and repetition, aiming for open positions, and emphasizing static advantages. If you are a fairly strong player and want the experience of playing against a simulation of an even stronger human player than yourself, we suggest using this mode and finding a skill level at which you can score 25% or so at your preferred rate of play.


Note that the Personalities are intended to be used together with the skill levels below 25, or with MCTS mode, but not with both. Note also that if you want to set Contempt to a different value than that specified by the non-default Personality, you need to select the White Contempt UCI option and set the value with the proper sign (flipping the sign if the engine is Black).

I tried the suggested romichess and like it very much. I would say it is actually FM strength (i am around there as well) and makes quite a positional and tough opponent, with a human style.

It has a very nice auto-learning feature and can learn from a chess games database. To make this possible, this is not included in the doc, you have to:

1) download your games database (i like kingbase lite) in pgn format
2) run the following commands
book_on
learn_on
quit

(yes, you have to restart once the program as far as i know)

And now, to build up the program's database with the self-learning algorithm:

merge mydatabase.pgn

If everything works, you will see the learn.dat file that comes alone with romichess increases in size while the database is processed and also in the command line prompt you will read the number of processed games.

Romichess has no GUI but can be integrated in ARENA.

Try RomiChess. It's a realistic FM-strength opponent.

Look it up on the page below, its download links are there, too:

Looks really promising. Thanks a lot!

Best engine for sparring

I am looking for a good computer sparring partner.

My experience with chess engines when you handicap them is that they don't often make very human mistakes, but that is the sort of behaviour I'd like to see from my silicon sparring partner.

My ideal would be a chess engine with a human style of play in the 2100-2300 range (and a wide opening book, but I suppose I could sort that out myself). I'm not so fussed about whether it's an app or a UCI engine.

Does such an engine exist?
