I don't have time to run any tests, but if either of you (or somebody else) wants, I can make a special version where LMR, null move and the tapered super-qsearch (which I suspect is also worth a significant number of Elo points) can easily be switched on and off. Alternatively, if it makes testing easier, I can add some compile-time switches which makes it easy to disable the features you want.bob wrote:if you have the time, go for it.

By the way, it's amusing to see that LMR is now generally accepted as effective. Back when I started advocating it, the technique was largely abandoned since many years, and those few programmers I managed to convince to give it a try mostly reported that it didn't work for them.
