learning about attacking different types of pawn structures, I would set them up on a board and just work, work, work on them. break defending pawn front with attacking pawns every possible way, find out how all different cases work out. when can you do it without losing material, when you need to ...[text shortened]... work on the positions, move those pieces around until your fingers bleed. then move some more.
I guess I'm not at the level to set up a position on a board and study it myself yet, but I got the point about bleeding fingers 🙂
