QUEEN AGAINST TWO PAWNS
Two pawns can fight against queens only if they are far advanced and have support of their king. Obviously, most dangerous are connected pawns, while isolated or doubled pawns can rarely save the game.
With king support, the biggest chance to draw have pawns on seventh rank, one step away from promotion. The stronger side can win only if its king is very close and does it by creating mating attack or by taking one pawn transposing to winning queen against pawn endgame.
