Steelman (steel man) - the opposite of "strawman"  - is a stronger version of an argument. When one opponent makes an argument, the other opponent tries his or her best to summarize and fortify the argument so that the argument's points are crystal clear to both opponents. After that, he or she refutes the argument. Despite being difficult this approach is extremely efficient at dismantling an argument. It allows to fully understand the position of the argument's author and come up with solid counter-arguments to refute the author's point.
