Specific Tactics Study

Does anybody know of a place where I can solve tactics by theme? For example, a set of pins, a set of forks etc.

yeah but it costs quite a bit to get a gold membership, if i remember correctly

Search for a book on tactics by Judit Polgar. It helped me a great deal. Easy to follow and suitable at your level.
