Apparently Fritz 14 is capable of reading the newer Syzygy format tablebases. Certainly the latest Fritz can. These tend to take up less space than Nalimov format, which used a simpler compression s …

Something very similar is doubtless encoded into AlphaZero and Leela's neural network evaluators, which are very positional. Most conventional Minimax engines, by contrast, are stronger at tactics … and can therefore search very deeply. Pawn structure is indeed a factor in most of the top engines' evaluation.
