Well, I told you beeawwb’s haiku would be tough and I was right! We’re going to have to drop a wee picture to make things easier!
But first, here’s the original haiku:
Throw down the Gauntlet

Fourplay? I can’t spell.
Then later beeawwb was good enough to drop this clue into the comments…
Square pegs will go deep.
This pile of old weapons has
a decimal point.
And, as promised, here’s a little image to get your neurons firing.
