play a hunch
To make a decision based on instinct, intuition, or an educated guess. The detective played a hunch and went to investigate the warehouse by the docks. Sure enough, that's where he found the stolen goods. There's no penalty for guessing, so if you're not positive which answer is correct, just play a hunch and don't second-guess yourself too much.
