What is the required Elo to beat a Grandmaster with queen odds? I heard someone saying today that he would beat Garry Kasparov if Garry played without a queen.

Were such handicap games ever played ?
Can a Grandmaster give queen odds and win against a 2000 ranked player?  Rook odds?
I have a hard time believing that there's a player on the planet who could beat me with Queen odds.  The strategy would be simple: trade off pieces pieces when possible.  I'm a USCF B player.

Here are some 'Queen Odds' games.  Play by the weak side is sometimes very dicey. Paul Morphy loses his game.  None of the games the GMs won went past 15 moves.  After that the Queen asserts too much power to overcome.

Here's a rant, lol.
