A quick correction to my post:

Here's where the tru= ly novel part comes in. Ruben solves this by extending the standard *TLC co= ntract:
1. Bob redeem with secret
2. Alice refund after= T1
3. Bob redeem without secret after T2

This is actually:

1. Bo= b redeem with redeem secret
2. Alice refund after T1 with refund = secret
3. Bob redeem without secret after T2

=
The fact that Alice reveals a secret when she refunds is crucial.
