Re: Nolot5 the worst test position
This position is evaluated as ''balanced'' or with only a slight advantage for white by many good old chess programs, the best old engines from a long time ago.
Nowadays, the fact that Stockfish considers all those moves as ''winning'' only demonstrates its extraordinarily deep understanding of the game and its impressive strength.

Many of the greats spent enormous time and compute power going over it. Many of the problems were analyzed for enormous time periods but both the engines and the computers were not up to par yet. Feng-Hsiung Hsu's analysis was clearly the best at the time:

Now, this test suite was intended as a positional test rather than a tactical one. Positional tests tend to be best suited to gradual test type analysis like that originally constructed by Odd Gunnar Malin. A typical example is Tony Hedlund's test suite (found via the wayback machine):
https://web.archive.org/web/20180713214 ... entest.htm
another one was the Strategic Test Suite that Swaminathan and I worked on originally:
https://sites.google.com/site/strategictestsuite/about
In general, test suites like these gradually fall apart to some degree as computer power rises exponentially and the chess engine strength rises exponentially. What used to be deep strategic thinking along important chess principles gradually become tactical exercises as the computer+software go deeper and deeper. Today's chess analysis systems are about one million times more powerful in both hardware and software than they were 21 years ago. After my multi-pv analysis completes, I will give problem 9 a much more thorough analysis because it has become the most interesting problem in the set. The most interesting thing is that the other ten were still considered correct by the analysis engine instantly (within zero seconds) but number 9 was not getting any love from computer+engine.

Re: Nolot5 the worst test position
Nolot 1:
Nxh6 is about two and a half pawns better than Kh2 (which probably also wins). No other move is better than drawing.

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Re: Nolot5 the worst test position
The dreaded Nolot 5, subject of the thread:
It appears that e5 has the best score with almost 12 pawns to the good.
Nce2 is also clearly winning with more than 7 pawns.
There are six moves that are better than 4 pawns ahead.
There are at least two moves that are 3 pawns ahead.
So, good test position? Yes or no?
I think it is not a great position to find the single winning move. However, it is still worthwhile to find out which move is the most devastating, and that move is e5. It would definitely be better formulated as a test which is scored with partial points for the less perfect choices.
