Pawns not only create the sketch for the whole painting, they are also the soil, the foundation, of any position.Anatoly Karpov
I recently picked up chess again and was looking for ways to improve my understanding of different pawn structures. This lead to me writing a small web app which allows you to experiment with various configurations (update: hosting was expensive, so as of 07/2023 I’ve taken down the site). Given a pawn structure, it looks at positions in its indexed games with that pawn structure and displays potential piece placements (transparency) as well as their likely outcome (hue). It also displays example games leading to that structure, filtered by game result. I’m not sure how useful it is as an analysis tool but hopefully somebody finds it interesting!
