If you let it run forever, it will eventually search all the depth 10 nodes required by alpha/beta pruning, but this will happen much further down the line---engine depth 40 or something. | |

Alpha-beta pruning keeps the search exhaustive, it just is able to prove that some trees are no better than other trees. But this wouldn't explain why stockfish produces better results as you let it run longer | |
| Jan 13, 2021 at 14:27 | comment | added | Cruncher | Depth 10 however, will eventually check all moves at depth 10. It simply uses heuristics to check the moves that are most likely to be good first, but if you let it run forever it will eventually exhaust all moves to depth 10. Stockfish is a brute force algorithm, but it's a hill climbing algorithm that will give you good answers quickly before refining them to be better | |
