Win or draw?

Depends.

Usually won.

The reason it is questionable is that if it is black's move at first, will he be able to pull of perpetual check in most positions?

It's queen and rook vs rook, not queen vs rook.

The thread title says its queen and rook vs queen not queen and rook vs rook and certainly not queen vs rook.

Should be won, even with Black to play. If White plays accurately he should probably be able to avoid perpetual I would imagine.

Well in most positions, Q+Q vs Q is drawn so I could only imagine that unless black places his queen poorly, then it should be drawn.

almost always won unless there is something immediate and forced. may take a while though

I actually heard QQvQ is won due to crosschecks (blocking a check to heck the other kig, thus forcing a trade of queens and winning the resulting ending).

That's a strange one alright...

The stronger side can try to force an exchange of Queen's, leaving a R+K vs K endgame, a simple win. A lot would depend on the initial position.

Q+R vs Q with both sides with pawns?
Avatar of browni3141

If there are pawns on the board it would make it much easier to win because the king can use them for shelter.

2Q vs. Q I would guess is almost always, if not always, winning no matter which side is to move.

Before black played Qc6+?, it was a draw in the example above. Even after black played Qc6+?, it is practically very challenging to win this endgame (if black defends properly, which is challenging to do). White has to find some only moves to win. But, the win is much easier if the superior side has pawns.

Queen and Rook would win because - 

  • There is more material.
  • They can trap the King to a corner quickly.
  • While focusing on the attack, they can also defend by capturing the opponent's queen.
    So, with the help of the queen and rook, White was able to capture the queen, leaving Black with nothing.

On move seven white could just check on f2 and force an exchange of queens and mate with rook and king.

I knew, but I am not that advanced to mate with a rook and king vs king.
