I'm a native English speaker and it doesn't mean anything to me as-is either. He probably meant "flat-out", which is an intensifier of sorts. I try to encourage all of my pieces to achieve the best they; they're my team, and I don't really despise any of them.
Witch piece do you out despise?
Ok... so we officially have ran out of ideas:
We have a thread for: Favourite piece \ Least favourite piece \ Piece that makes you ill \ Piece you dispise... Where does it end?

Piece you'd least want to fall on, or step on, when going for a midnight wee.
Or which piece looks most like Mick Jagger?
After these two I think we will of completed the, what piece forum, chant and realise the Dragon of ultimate knowledge. In which case I'd like to ask it it's favourite piece.
My opponents knights, they are spawn of the devil and must be destroyed without mercy.
Also my opponents queen bishop.
WELL???
