How do I play after the double hane on S14? I really wanted to play it, but I was worried about being cut at R14, and I didn't see any valuable options after that.

The double hane doesn't look great to me in this situation, actually. Not bad, either, though. The usual continuations (when the marked group is short of liberties) are like this:
