Hello Marco,

I'm not very good with this git stuff, but I forked from your repo, and commited a patch to my branch. Test results are promising so far.

I don't know if this "pull request" thing is the way to do it: we'll see!

pull marco's master branch
@lucasart lucasart Remove Threat Extension
Gret code simplification:
- instead do not futility prune threat refutations. allows_move() is therefore removed.
- also remove the !PvNode conditions from SEE pruning (search and qsearch)

4000 games at 50,000 nodes/move:
1085-989-1926 [51.2%] LOS=98.3%

4000 games in 10"+0.1"
756-751-2493 [50.1%] LOS=55.1%

Hi Lucas,

This looks like an interesting idea! My testing is not looking great for it so far though, at 10+0.01:

ELO: -8.83 +- 99%: 15.50 95%: 11.77
LOS: 0.27%
Wins: 424 Losses: 509 Draws: 2413


I think Marco pushed this so you should be able to close the request.
