🧮 Branching Factor & Tree Complexity
| Depth (half-moves) | Avg Branches | Total Nodes | Exact Positions |
|---|---|---|---|
| 1 (1 full move) | 20 | 20 | 20 |
| 2 | 20 | 400 | 400 |
| 4 | 30 | ~8,900 | 8,902 |
| 6 | 30 | ~9.1M | 9,132,484 |
| 10 | 35 | ~70B | ~7 × 10^10 |
| 40 (full game) | 35 | ~10^123 | Shannon number |
💡 Tip 1 — Candidate Move Rule: The number of positions you must calculate grows exponentially. At depth D with B branches per move, total nodes = B^(2D). For a mate in 3 with 3 candidate moves, that is 3^6 = 729 positions — manageable, but at 5 candidates it becomes 5^6 = 15,625.
💡 Tip 2 — Piece Activity Score: A practical complexity score for any position = (number of legal moves for your pieces) – (legal moves for opponent). A score above +8 typically signals a strong tactical opportunity. Use this calculator to estimate how many positions you need to analyze before finding the solution.
Chess Puzzle is made up of a Chess position, in that one uses logically the knowledge about pieces and rules for solving a problem about Chess. For instance it can involve something like “mate in two” or simply identify the best move. The origins of those Puzzle extend until the Middle Ages, and they continuously evolved from then until now.
