Disclaimer: this post is going to be extremely vague. So don't expect a result with what you can do something. It are just whirling thoughts that hopefully will lead to something useful in the future. Yeah, I know, I did better not to post it. But to write it down helps me thinking.
I have looked close at the position of the previous post.
What I found the most astonishing in the position was that in every single line of white black wins a piece. I think I know how that works approximately.
There are different kind of moves.
The one-threat move. If you move a piece, you can use it to threaten something.
The un-one-threat move. If a piece is threatened, you can escape the threat with this move. Most of the times it delays the threat.
The non move. This move doesn't threaten anything nor does it relief a threat. Usually it hands over the initiative to the opponent or it allows him to cash in the threat.
The duplo-threat move. With this move, you threaten two targets with one move. For instance a double attack, a fork, a discovered attack, a skewer etc..
The un-duplo-threat move. With this move you can relief two threats at once.
A game can flow as follows: the side with the initiative starts. Threat-unthreat-threat-unthreat-threat-unthreat- threat-unthreat-duplothreat.
Once there are two threats, a piece is going to be lost, since usually only one threat can be parried at the same time. You can start a counterattack, but that only delays the cashing in of the duplo threat. Once two targets are attacked, you are going to lose a piece, no matter how much delaying moves you play. This is the law of conservation of threats. Only if you play an un-duplo-threat move you can save the piece. Or if you play a duplo-threat move yourself!
So if Fierabras feels that he must win this as black he is right unless white can play one of the rare moves!
As said, this is all probably very vague to you. But believe it or not, this is what I actually see in the position after a few hours studying it. And since it can be seen, there is no need to calculate every line. But it is all still rather shaky.
