How is the playing style of your nnue implementation? Well, it's hard to make general statements about playing style. I would say it is more human-like, even though it was trained on engine games, because it is less reliant on arbitrary rules that might not be appropriate for a given position. With...

Great stuff, Frank! Turning a Ruy Lopez/Spanish into what's basically a King's Indian and 'extending the chain' with 14...f4, resulting in a raging attack on the King! John Stanback has done a marvelous job with Wasp.

Not too many years ago, chess engines couldn't quite attack like this.

It's been showing up as a positive in most scans. You could try Tony Mokonen' compilation:

Incredible elo increase (+445 elo) for Scorpio 3.0.10NN dh2. I wonder how much of this increase is due to the network. Daniel means: this shows, how bad his own eval functions have been. He will somtimes make an own net. I will not test this engine without the net - so your question can not be answ...

Yeah, in many ways it's a sad state of affairs when you just plug in SF-NNUE as a shortcut. The worst part is that it's a black box that doesn't even let you set contempt, let alone other settings. It takes the fun out for guys like Brendan and me, and also for some conscientious programmers like An...

OpenTal 1.1 introduced some changes to search (and in other places, but not sure) that somehow reduced the engine's aggressiveness. It probably made it see more refutations to its attacking moves.

Keep in mind that these Rodent personalities will usually reduce strength, but enhance style.

The only objective way out of this dilemma is to use default settings, I'm afraid. If you want to try different contempt, then you'll be testing a (slightly) different entity than the original engine. If stronger engines are stronger with default contempt, then so be it.

Quiet clear is: Engines based on strong endgame sources like Rybka / IPPs have a 2-3% higher move average as most of others, not based on that sources. Can be see in all of my rating list systems. Equinox, IPPs, Rybka versions and so one. I will not say Hannibal or Demolito based on IPPs (that is n...
