Go up one level in this thread

There are 2 main use-cases of "perft" command for user of your program:

1. Measure [relative] speed of your move generator at given hardware
2. Check your move generator and guarantee that it works without any errors.

I think, that the second task is much more important for me as the user of
Movei, than the first one (there are many other ways of measuring effective
speed of the engine... and usually I'm interested not in pure move generator
speed, but in overall speed of "movegen + search + extensions + pruning +
hashing +..." combination).

So, my advice is:

do not specially change your move generator code just to increase it's speed in
"perft" test.
It should be the same (with all features and bugs) that your engine uses in real
games.

We don't play perft, we play chess :))
