Resource for Chess Problems about particular topics Most puzzles I find are where payout is relatively high. e.g mate in 2-3 moves, play right and get a piece etc. However, I needed a resource which gives me some puzzles/exercises about particular topics in chess where payout is not that high. For example puzzles focussing solely on whether to exchange a piece in a given situation or not. Or whether to be aggressive or defensive in a given scenario. Chesstemp does have tactics tags in its puzzles but I was not able to work out how to get puzzles solely with a few selected tags. Thank you for your kind help
