Hello.
Do you have any tips or learning resources on queen endgames? I recently encountered 2 queen endgames where I had 2 extra pawns, lost the first one, and nearly lost the second one. I found that it is usually pretty difficult to calculate defense from perpetual checks which will not lose any material.
