I'm not sure exactly what question you're asking, but here are a few ideas related to why rooks might be stronger than bishops: Bishops are easier to block with pawns. If a bishop sits on a nice open ...

What is the most suitable position for a bishop here?

In the diagrammed position you have a material advantage but Black's position is a little bit better because his rooks are connected and he has a safer king position. His immediate threat is RxR, when ...

What is the most suitable position for a bishop here?

Brian Towers' answer is excellent. I'll just add this: if you play Rxe8, you are effectively trading your e1-rook for your opponent's a8-rook. A glance at the position should show that your e1-rook is ...

Can I place my rooks upside down at the beginning of the game?

The FIDE laws of chess say nothing about upside-down rooks. However, starting with upside-down rooks is silly and if your opponent complains that it is annoying, I would expect the claim to be upheld. ...

Two Rooks vs Queen endgame

Generally speaking, it's a draw. Most pawnless endgames are drawn, unless one side has a material advantage of more than a minor piece. Either side can win if there are short-term tactics. To check ...

Bishop and Knight exchange with opponent's Rook and pawn

In the middle game, where pawns are generally less important than the endgame, two pieces are better than one. So, in the middlegame the bishop + knight are worth noticeably more than the rook and ...

Not able to use rooks properly

Is a queen for two rooks reasonable in this position? What are the disadvantages?

This is a losing position for White. Normally, trading for a queen against two rooks is reasonable but Black has an extra knight here... The best objective move sequence would be: 1.Qxe8 Rxe8 2.Rxe8+...

You say your opponent had a strong attack against your king and you had to "sacrifice" your rook for two minor pieces and went on to lose. I think you have it the wrong way round. It sounds like your ...

When is a queen stronger than two rooks?

As a general rule, two Rooks tend to be stronger than a Queen. Typical endgames like 2R+5P vs Q+5P are much better for the rooks who will coordinate to attack the opponent's weakest pawn. However, ...
