Glaurung 2.2 NNT is another glaurung clone (pardon, derived work).

It is based on Glaurung 2.2 by Tord Romstad and modified by Volker Annuss without looking at any Glaurung modification.

I don't want to find my source code in clones, so the only way to recieve a copy from me is to promise not to give a copy to anyone but Tord Romstad.

Glaurung 2.2 NNT is distributed as source code only. Of course you recieve all the rights the GPL V3 (the original Glaurung license) gives you. This includes the right to modify it and give copies away. But remember, you recieved it by promising not to make use of this right and the GPL does not force you to do so.

Changes
- Timing using Neural Networks
- Simplification (Bugfix?) in LMR
- Bugfix in move ordering

Expect it to be 5 or 10 ELO stronger than Glaurung 2.2.

If you want to get a copy, please send an e-mail to glaurungclone [ät] nnuss DOT de.

I will send copies to trusted testers only.
If you don't get a copy, no reason will be given. This does not necessary mean, that I don't trust you.

Greetings
Volker

Sorry Volker, but what you ask for is exactly the opposite of the most fundamental point of the GPL that Tord decided to apply for glaurung publication.
You simply are not allowed to ask for such a promise.
_This_ is a breach of the GPL. The reason why you were allowed to have a look at Tord's code and base your modifications on it is precisely that _you_ "promised" not to add any restriction (be it a soft "promise") to the general use of your added code if you were to publish it.

You are infringing the GPL when you ask for such a promise.
Either you keep your code for yourself or you publish it and you are not allowed to ask for any restriction on its use as your code itself is based on a GPL source.

With all respect: this is laughable. Its questionable if your request is a violation of GPL in itself but I will not ask for such "privilege" for sure. And I encourage others to share my point of view.

The word right indicates that it can be excersied according to will, there is no question of force involved. You can probably ask them for a personal promise, but it won't be legally binding. If you derived your code from the original source which was licensed under GPL, you must abide all the terms and conditions of the GPL and forward this right (the same right you excercised by modifying the original code) to everyone else who receives a copy of your derived work.

Oh, and when asking for voluntary testers, a more friendlier approach would help.
