It is intersting to see what is the maximal rating difference that we can see surprised mot because of obvious bugs.

big surprises in the games are

1)the draw of
Movei00_8_438 32768 nodes with rating 1986.6 against Stash v35.0 512 nodes(rating 1000)
surprisingly a relatively good game of stash.

2)The win of
Movei00_8_438 2048 nodes(rating 1345.1) against Black Marlin 9.0 4096 nodes(rating 2067.5)
Movei lost a piece in the opening but 4096 nodes were not enough for black Marlin to see mate in 1.

Movei00_8_438 2048 nodes(rating 1345.1) caused another big surprise by drawing against Igel 3.5.0 4096 nodes(rating 2025.1).
In the opening movei blundered by developing the queen and blundered and had to lose the queen for a bishop but the horizon effect caused movei to blunder and be a full queen down.
Igel sacrificed the queen to get a simple win with rook and bishop advantage but then started to blunder and finally failed to win KRK endgame.

I replaced velver by a new version and added 2 versions of stash and one version of smarthink to the engines

Edit:I see that the problem was in the original rating list that had
45 Koivisto 9.0 8192 nodes : 1108.3 8.0 34 24
49 Koivisto 9.0 8192 nodes : 1043.3 18.0 40 45

Maybe I forgot to upgrade Koivisto and this is the reason that it happened when it participated in higher league..

1. Engines most probably have a different definition of what a node is like counting qsearch nodes or counting nodes resolved by TT.
2. Engines may not stop at _exact_ number of nodes.
3. Most engines play disproportionately worth at low depth = low nodes count.
4. Best move selection may be buggy at fixed nodes count interrupting the search as it is shown by illegal/missing moves at very low nodes.

I understand engines have a different definition and that they sometimes do not stop at exact number of nodes.
For me results are still interesting because I hopefully get a list of deterministic engines(not 100% sure about it but I basically test and found that when I played 2 opponents with the same color twice I get the same number of moves and probably the same games because if it is not the same game the proability to get the same number of moves is small).

I agree that best move may be buggy at fixed number of nodes and I think that if it is the case it is something that is better to fix because the need to intertupt the search in the middle of the iteration can happen also in normal games(there is always a problem if to trust fail high that you did not solve or not to trust it and it is hard to test in normal conditions what is better when you practically need to play a move before you solve the fail high only in small part of the games).

Usually the main advantage of the strong engines is simply that they get more from doubling the number of nodes at the same playing strength.

I would like to see some function of equivalence in number of nodes between different engines and it may be possible to learn from results about this function.
