During our last play session (it was our second session, so everyone is first level) my fighter dwarf had a conflict with another player's human fighter. My dwarf became annoyed at the human's dismissive reaction to a roar outside the village that sounded like ogres (my dwarf has a bad history with ogres).
So, in order to emphasize the seriousness of this situation, my dwarf grabbed the human by shirtfront and pulled him closer (done with a successful roll). Still bent double, the human drew his sword and pointed it at my dwarf's belly (dwarf wearing chainmail). At this point the DM made the other player roll an Intimidation (Charisma) check, and me a Wisdom check to resist. I lost and my dwarf, chastened, let the human go.
That was pretty funny situation, but one thing is bothering me. By using a Wisdom check against Intimidation (Charisma), my dwarf (who has −1 Wisdom modifier) was at a disadvantage (literally, not in the D&D disadvantage mechanic sense) against the threats. Although he is a strong and capable warrior, he is not that wise.
But I have to wonder: is willpower really represented by Wisdom in 5e? I think that many not-so-wise creatures/characters can stand bravely against threats.
What ability/skill should be used in a contest to resist intimidation?
