the "Black Hole" generator ("AI")

[Pi4Chess]

When I make Sting play white 2 sec move against another engine in this position it always end in draw by 3 fold repetition adjudication.

When I make Sting play white 2 sec move against another engine in this position it always end in draw by 3 fold repetition adjudication.

Try more time per each move.

But it is not the end of the "Black Hole" idea.
The first problem: One of many decisions is wrong but has huge advantage (described above).
The second problem: One of many decision is good but a success is far or out of range.
It needs an "intuition" and Sting 25 has it.

To prove it, I selected: nate in 74 - Popov & Khanyan.

Here searching has no sense, the solution is too long.
I started auto-playing (Sting vs. Sting; common hash) with only 2 seconds per move.
Sting 25 avoids draws ("Black Hole") and selects the all correct moves of the long plan only thanks to the "intuition".
