Plan a Chess Study Programme for a Beginner

Most beginners pour hours into openings before they can spot a simple fork, which is like memorising vocabulary before forming a sentence. This builds a three-month plan in the right order: the one skill that lifts your rating quickest in month one, what to add once that is solid, and where openings finally fit. For adult beginners who want to get better, not just busier.

**Design the three-month study plan:**
1. Month 1: the one skill that gives the most rapid rating improvement
2. Month 2: what to add once month 1 fundamentals are in place
3. Month 3: opening basics and when openings actually start to matter
4. A daily practice schedule of 20-30 minutes using free resources
5. The single mistake that holds back most beginners
