Truly poisoned pawns

I was playing around trying to find some ways to trap queens that go pawn hunting, especially on b2/b7 or g2/g7. Then after reading the positional? thread I thought of steinitz and run into this gem which I didn't remember.

Here is the position where black goes wrong. Qg4? Then eats a g pawn and finds out the price.

No pawn grabbing, though I tried on g7, but a very early Queen trapping!

I posted this one before, but there it goes:

White's queen grabs three pawns, and suddenly finds itself chased all around the board, giving black a strong attack, with an unsound sac leading to a mate

Some smashing instructive errors on this thread.

Here are two under 10 moves Queen wins played on here by me.
One with White and one with Black.

First. All I did was develop.
