I dont like doing this, unless its only a Rook and Rook and some pawns vs Queen and some pawns endgame..
But thats just my Oppinion
I had a simul game against an IM where he had a queen vs my 2 rooks but we ended up drawing.. If only i can find it.. Ill get back to you if i do.
When is it a good idea for to trade your Queen for two Rooks? When isn't it a good idea? I've had the opportunity to do this a couple of times lately, and it always makes me nervous.
