Korean wonderkid Shin Jinseo 3p gave us this rather nice little problem from the 2nd game of the final of the 2nd Let's Run Park Cup. Black ignored white 1, what is white's awesome follow-up?

Answer:

Very good problem. I had a hard time understanding the order of playing 2 and 4 (why not starting with 4 for example), but I think I get it now.
