How to play with Queen?

I have seen many books, tutorials, videos etc which deals with the topic - How to play with bishops, knight and rooks , even pawns. These study materials actually tell you how to make your pieces active, favourable conditions for them, etc.

However, I found it very rare that someone is explaining how to play with queen. This might be because of following reasons:

1. It's very easy to play with queen and everybody knows it.

2. It's very difficult to find out the pros and cons of positions for queen.

3. It is ignored.

That's a good point and then we can use that madness against our opponents :)

lok at some GM games for ideas.l

Uses of a queen:

1.Can control e5 from c7 in many Sicilians

2.Centralize her in the endgame as the long diagonals are perpetual check diagonals.

3.Some will say to move your queen last of all.  However, I like the 4...Qb6 Sicilians so I don't completely agree with this advice but generally works (for example, 2.Nf3 is better than 2.Qf3 and 2.Qh5)

4.She is the strongest attacking piece.

5.Perpetual check always looms in queen endings so always calculate accurately to avoid it... unless you're the inferior side, in which case you should pounce on the moment to play it.

6.She generally belongs behind rooks when forming a battery as pieces in front are first in line to get traded.  An opposing rook would make a queen step aside (unless you win the exchange a queen for two rooks, in which case two rooks for the queen is a pretty sweet deal) whereas the rook in front maintains the tension and reserves options of exchanging.

Just make sure that you don't expose the queen too far before you develop. I have had many players rush to take my rook with the queen while I set up an unstoppable trap. When the queen goes into the corner, there is a trap set up with pawns, bishop and I think the knight (don't remember well but if I find the sequence I'll post it). I can't exactly describe how I set up that trap, but if the other player develops well, it is very easy to do it intuitively. Also just a rule of thumb, avoid putting the queen in an adjacent square to the king if there is an opening in early game. A rook or bishop can threaten the square and force the queen to claim the defended rook or bishop and lose the queen, or you will be forced to sacrifice it to keep the king covered. If it is late game be careful of double attacks by knights and rooks and bishops that are checks.

Oh think long and hard before you snatch a b-pawn if a queen is on b6.  It's usually a terrible idea.  Only Fide Masters can hold the pawn in the poison pawn Najdorf, but why even place a queen there anyway when there are better moves such as 6...e5 and 6...e6? 

This is an example of how not to use your queen. White plays the horse to block the queen in rather than threatening directly because the queen can check the king to get free. If you box the queen in, the value of the queen is not good. Plus the development of black suffers and there is a setup for a check to claim the rook with with Kc7+ if black doesn't do anything about it.

Black could have developed more before deciding to go after one measly pawn.

There might be a flaw in playing Kb5 so disregard it, but just avoid placing your queen on the b pawn. TheGreatOogieBoogie is right. The development that I placed is not very realistic for a good player.

It's called a knight, adrianbetween.

And it's very simple. There are scenarios like this where it is a good idea to capture with your queen. And there are others where the advantage is not that major.
