which engine would good at finding the mate in 33 here without using tablebases. ?

There are seven winning moves four of which lead to mate in 33 and the other three lead to mate in 34.

Fruit prefers Bg4, Ba4 & Be8 (mate in 34) before finally settling on Bh3 (mate in 33) after 2 mins 37 secs.

My hardware is quite primitive by todays standards though. I would like to install the Stockfish engine for Linux but I do not how to use the makefile provided.

For help, just type "make help".

You likely want to run:
"make profile-build ARCH=x86-32" or for very very old hardware
"make profile-build ARCH=x86-32-old"

I tried the position on fruit 2.31 and after 15 minutes (on 4 threads, 2 billion nodes) still has not found the mate. it gives a score of 7.47.

just to confirm when it chose Bg4, Ba4 & Be8 , did it announce mate in 34 ?

No - only an EGTB could do that on my system.

Thanks but where do I type "make help" and how do I run that?

I know how to access the terminal but have no idea how to use it.

JA Linux compiles should run on a cpu as old as Pentium Pro.

OK, open a terminal.

cd /home/yourusername/stockfish-1.8 (this assumes you placed the stockfish source code in the directory named 'stockfish-1.8' in your home directory.)

cd src

make help


Note:

You will need to have g++ already installed on your Linux system. For Ubuntu (what I use) that can be done (before the above) with:

sudo apt-get install g++ (and supply your password when prompted)
