Yeah, that’s not the latest torch. Hopefully they’ll push it out soon.

I hope not. We haven't stopped testing Torch v2 yet.

That's all fine and good, but Berserk 13 does solve this mate in 23 by Peter Krug in a little over 2 minutes on my computer that lots of other engines can't including The Huntsman 1, Stockfish, Crystal, Komodo dragon, (I can't say for lc0 because I don't have it) and a host of others:

My point here is that we can ALWAYS find a position that one engine might not be able to solve, but there are others it will solve that will make the other engines look dumb that can't solve it. It has something to do with the pruning methods and you can't account for everything or every possibility without sacrificing something.

That's all fine and good, but Berserk 13 does solve this mate in 23 by Peter Krug in a little over 2 minutes on my computer that lots of other engines can't including The Huntsman 1, Stockfish, Crystal, Komodo dragon, (I can't say for lc0 because I don't have it) and a host of others:

My point here is that we can ALWAYS find a position that one engine might not be able to solve, but there are others it will solve that will make the other engines look dumb that can't solve it. It has something to do with the pruning methods and you can't account for everything or every possibility without sacrificing something.

I think the issue is a bit deeper than that. There apparently is a trade-off between average performance and reliability. And engine developers tend to only focus on Elo, which is an average of the move quality over many thousands of games and thus many millions of positions. If they can make the engine find the best move in 99.9% of these positions 1% faster, they don't care if that makes it a factor 5 slower for the remaining 0.1% of positions. Because on average it would still be marginally faster. But from the perspective of reliability this is of course a large degradation of the engine quality.

"A man waded through a river that was 1m deep, and got across safely. A statician waded through a river that was on average 0.5m deep. He drowned."

What makes it even worse is that the penalty for having difficulty with some of the positions does saturate. Once the engine needs more time to find the decisive move than what was available in the test game, it simply loses that game. It doesn't matter if it would have taken it 10 times as much time as was available to find the move, or 1000 times as much, or even if it would have not been able to find it at all, no matter how long it could think. The developers are more than willing to sacrifice the engine's ability to solve positions that rarely occur in games for marginal Elo inprovement, and the saturation effect makes it quite easy to do that.

I don't think it is true that there are always positions where an engine must perform very poorly. It was a choice of the developers to completely sacrifice such positions for the 'greater good' of marginal Elo improvement.

So these top engines are not really good engines, in the same sense as that a river with an average depth of 0.2m is not a ford, and that one with an average depth of 0.19m would be a highly superior ford. They have become low-quality products that you cannot rely on. While for analysis it usually isn't very important whether you get the correct result 10% faster on average; it is much more important to always get it in reasonable time.

Suppose you had to make a 100km car trip, and had the choice between two routes. One (the interstate highway) would allways bring you to your destination in 60 min. The shortcut would bring you there in 50 min, by taking a private ferry near its end. But once every 14 days the skipper takes an unscheduled day off, the ferry doesn't run, and you would have to turn back to take the other route anyway, which in total takes you 42 + 42 + 60 = 144min. So 84 min extra with a 1-in-14 probability is on average 6min delay, so the average travel time for taking the ferry would be 56min, 4 min faster than the highway. Which route would you prefer?
