How to use StockFish chess engine with Shredder chess GUI

Stockfish:
This is one of the top chess engines in the world. It’s also free to use under the GPL license.

Download the latest Stockfish build from https://stockfishchess.org/

When downloaded, unpack the zip.file and take note of the folder you unpacked it to.

Shredder:
I tested several different free Chess GUIs in 2015. Some were horrendous, some were quite good but a little buggy or inconvenient. Shredder is the one that delivered the absolutely best experience.
Shredder has a 30 day demo. After that, it costs €30.

The more expensive Shredder’s, Shredder 12 and Deep Shredder 12, are not worth the extra money. As far as I can find, the only difference is the internal chess engine. We’re going to use Stockfish instead.

Download the Shredder Classic 4 demo from http://www.shredderchess.com/chess-download/free-demo-download.html

Now install Shredder and start it up and follow this procedure:

Install the engine

* Within Shredder, click Extras – Engines – Install Engine…

* Engine type = UCI Ok

* Click the …-button to select the folder where Stockfish lies. Select one of the engine files. Try stockfish 7 x64 popcnt.exe first if you have a modern computer. If it doesn’t work, try one of the others. Ok

* In the next window, you can change the engine name if you want. Ok

* You get a message saying it was successfully installed. Ok

Modify the engine

* First make sure the engine you installed is selected.
There’s a clickable button just below the chess board that says which engine is installed. Click it to select the Stockfish engine.
* It then tells you how much free memory you have and asks how much you want to use. Write at least half of what it says. Ok.

* Click Extras – Engines – Engine Options…
For multicore cpu’s, edit the number of Threads to as much as you want. Personally I use half the cores of my cpu (I have an old 8-core AMD-cpu, and I use 4 threads). Ok.
