They will usually agree when the best move is a pawn or more better than its competitors. How long should you let each programs (engines) run? It depends on the relative rankings of the candidate moves. If the best move is a pawn or more better than its competitors, maybe an hour is long enough. Rule of thumb is to let the software (engine) examine at least 5 billion positions (nodes) if you are looking for the truth in chess. Depending on the speed of your computer that can take several hours for each program (engine) run. That's the ideal but in practical circumstances there may not usually be that much computer time available!? That's probably best in most cases. But occasionally only a deep long search can find the best move, in which case you pick your best program (engine) and let it run til the cows come home... :) WP
