Sting-sf-45 release

[lech]

Many thanks Vincent for your examples. One of them is very useful and show that my idea (sting-sf-x) needs much more work.
The problem how to get the value draw leads to the reversal question how to avoid a zero value. The second question seems to be much more difficult. It is not easy to get the proper code even if an idea seems to be be good.
In my warm head there are new ideas and I believe in the future I will do it much better, though.

Thus the version 4.5 of Sting remains now my new official release and if Jose is able to help me too, 64-bit compilation is welcome.

Many thanks for any help again and sorry for the confusion,

No problem, Marek.

The current code by mediafire is valid?.

Thanks Jose.

I hope all is ok.

In the lock.h file I remained active #if !defined(OLD_LOCKS)
I don't know what it means?

It would be very great to have a SF-Solver (as in the past Rybka-Winfinder and Tactical Houdini 3 and 4). But draw detection added.
On Wikipedia, you can find some very interesting fortress too : http://en.wikipedia.org/wiki/Fortress_%28chess%29
This great one : Nxe4!!

Later I'll put it on my blog,
Popcnt Intel version, and version easily.
Microsoft XP version with OLD_LOCKS.

Marek, maybe you should make an effort and move the code to the new Stockfish,
Not only for performance, even modernize .
Users can compile their machines with system BYO, example.

My modified Stockfish gives Ng4.
Wiki says:
White would lose after 1. Nd1 Kc4 or 1. Nh1 Be5 or 1. Ng4 Bg7.
I cannot see the white win after Ng4
Kind regards

I think your question is "Does Black win?"

[BBauer]

Sorry.
You are obviously right.
My question is: How can black win after Ng4

Kind regards

Many thanks Jose for your compilations.

I am afreaid to use any version of Stockfish and to find a horse tail in my bed. Seriously, it is rather your last help.

[ Seriously, it is rather your last help.

Not there is a downside, it's entertaining.

But I see Sting almost 50 percent slower than the latest Stockfish.
And it's not your goal Marek, but fans always compare brute force.
