"In Russia every school boy knows better!"

In 1972 started world championship between Russian titleholder Spasski and American challenger Fischer. Fischer had played brilliantly in the candidate matches and now whole Russia feared him to "rob" the title from the best chess country in world.

29. ...Bxh2

So was Bxh2 at last a ingenious  move? Do you see a winning plan for white?
