The olympiad system has a multi-tiered structure, which explains the variety of resources available: Combinatorics This specialized blog is a fantastic resource
The official portal for the All-Russian Mathematical Olympiad (often in Russian, but easily navigable with modern browser translators) archives past problems. When a solution introduces a trick you have
When a solution introduces a trick you have never seen before (e.g., using the Pigeonhole Principle in a strange geometric context), write it down in a dedicated notebook. Revisit that problem one week later to ensure you can solve it from scratch. Conclusion
