I'd be interested in seeing games won with a Queen handicap. How does one go about this?
I think that it might be easier (in a practical sense) to overcome rook odds than knight odds. The knights plays an important role early on, and one is deeply missed when gone. The rooks only come into play later, and there are many games that conclude before the a1/a8 rook has moved.
The queen is both more powerfull than the rook, and much easier to bring into the game. Therefore, I think a Queen handicap is almost impossible to overcome.
I think I could easily beat a Grandmaster at Queen odds, since I have already beat masters and drawn senior masters without odds in USCF tournaments. A queen is a lot.
