One H1 with several H2 tags is fine.

Chess with the Czar lasted eleven winters. He moved a pawn. I took a nap. He moved a knight. I had a son. When at last I won, the queen on the board winked at me, and the Czar sent me a sleigh full of plums for my trouble.

Pisa had a straight tower until I leaned on it to fix my shoe. I heard a small creak. Nobody else saw, so I tipped my hat and strolled away. The town has since made a good living from my bad habit, and I have never asked for a share.

Stripes were my idea. A plain orange tiger came to me in Bengal, sad and easy to see. I took a burnt stick and drew on him while he held still. He hunted well after that. Soon a long line of tigers stood waiting outside my tent, each one purring.

Egypt owes its floods to my bathtub. I was washing near Aswan, in a tub carved from one block of stone, when I forgot to turn the tap. The Nile rose and the melons grew. A grateful local ruler sent me his thanks and a rather large bill for carpets.

Clocks.
