Hi Franz, I use 32000 in Kiwi and Arena seems to display the score correctly. I don't think 10000 or any other number is better or makes work particularly easier for the GUI. In fact, when I was designing my own GUI, I decided that it was a good idea to run a simple "mate" and "get mated" test on new engines when possible, so that returned scores could be compared with known values.
