My thought is, you have the only bishop. I would have simplified like this in a heartbeat because I could win this game against anybody. Black has no counterplay so the game is just details at this point -- and easy details.

white easily wins the position after the queen trade, he just has to use his bishop and more importantly his king. You move your king up the board and either go on his king or queen-side. Strategic pawn moves should also be made. And even if black gets a chance to promote, you can always sacrifice the bishop, so a very easy win for white.

How about no B?  is the Q worth 2 Rs? On paper the Q is 9 and Rs are 5 each. However worth can be realtive to how playable the pieces are.

you should normally trade a queen for two rooks , yes.

If you look at this game, without the bishop it's not so simple as 10 > 9. If you decide to trade the queen for two rooks, you are entering a king and pawn endgame. You should know whether you are better or worse in the endgame when you do that. In this position, I think black's pawn structure is a little better, though I'm not certain if it's enough to win. Also, what are the alternatives to trading? In this case, it looks like the white might be winning some pawns by keeping the pieces on.

 Kasparov or even Dembo? Don't think so...

Honestly, in the exact position where the queen and rooks have already been traded and I have the only piece on the board. Yes, I believe I could beat Kasparov. It's a technical victory, not a creative one -- that's the point of saying the opponent doesn't matter.

"Yes, I believe I could beat Kasparov."

 

Of course. With the White pieces in the final position I could crush the GM or computer of your choice. And they would do likewise if they had the White pieces!

Yes, the hard part is to get a piece up on Kasparov in the first place.
