In computing it basically means checking every option in order to find a solution.
For actual human chess players the term is rather subjective, it all depends on where you read it. I would take brute force to mean an uncompromising crush, taking few risks so that everything can be accurately calculated.
I've heard people talking about winning by brute force...does that mean that one player makes a series of moves from which there are only set responses/ only one possible move replies? In other words the opponent's hands are tied?
What does brute force mean exactly?
