Son, don't take the b pawn

There is an old chess tale about a father leaving hos fortune to his only son, on the condition that he never captures the b2 pawn with his queen in the opening. While the story is almost certainly invented, the advice is usually pretty sound. The one possible exception is the Sicilian Poisoned Pawn variation, but event then, opinion on this is still divided.
A very recent example of the danger that the queen can find itself in is from the current European Teams Championship. Black was only a little behind up until move 20, but after grabbing the b pawn, he only lasted another 3 moves. Maybe he missed 21.Ra1! but knowledge of a bit of ancient chess humour would have helped immensely.
