This puzzle you can get without being "clever" by just following the logic:
Suppose Alice got Heads. Say she guesses Heads. Then when Bob gets Heads they win. When Bob gets Tails Alice is wrong so Bob needs to guess Heads when he gets Tails.
Flip the scenario around when Alice gets Tails and you get the whole strategy
