Queen vs. 2 advanced pawns endgame

I cannot find any information on queen vs. 2 connected advanced pawns endgame.  Whenever I get in this situation I only seem to be able to draw at best.  Please inform me if there are any ways to force the win.  Any examples and input is greatly appreciated.

What if both are on the sixth rank?

What if one is on the 6th and the other on the 7th with the king nearby? That can be a draw.

 ok analyze this one then, my previous examples were not the best, white to move.

i swear ive been in these situations and its not as simple as looking a couple moves ahead.  Probably in time trouble at this point anyways.

Thanks paul that site is very helpful.

White is lost in the below position. No matter what white he does.

The black queen will blockade the pawn.

Here is an example of what IM pfren was talking about

The below diagram is a draw. The main reason is because the black king is to far away from helping the black queen and the white king and the pawn can not be checked in such a way as to allow the black king to move closer. Due to the rules of Stalemate.

Now here is a comparision to if the pawn was not on the A file.

Black in this situation win's.

Usually the way to win Q vs pawns is to check keep checking the king until your queen is at the right place when you can park the queen right in the path of the pawns. That stop the pawns and let you slowly move your king over to win them.

For there to be even a doubt of draw, the 2 connected pawns need to be already on the 6th and king need to be already supporting without fear of being cut off (e.g. b6 and c6, king on a6), and white to move. Even that black often wins if the king is close enough.

If you try a few examples you will find that it is really easy to stop the pawns if it is not an objective draw. Either the queen is able to stop the pawns directly or the king is in time and it is an easy win as white can't move without losing a pawn.

I tried to make an example but I find it too trivial to put up as it is very obvious if you see the moves.

how about 3 pawns, or pawn and bishop.

All the input has been very helpful, just don't want to get to a favorable endgame and find I don't know what to do.

This site is nice but it doesn't show the moves played out,  Just says "losing, mate in x moves?

Or this, how would it play out? Drawor loss any why?  I guess theres so many different lines you need an engine to sufficiently analyze.

You click on the losing in X moves to go through the line.

The January Chess Life has an interesting  example in Lev Alburt's column. I will give only the final moves here, although Alburt analyzes the entire game.

nice examples.
