The interesting thing about the challenge is the comments you can read from the experts. They explain why they prefer certain action, and usually more than one expert will point at details you might have not even thought about. Last month, for example, there was: ♠A8xx ♥QJx ♦AKx ♣753 And the auction had been: 2♠ - 3♥ - 3♠ - ??? Most experts chose to bid only game. Yes, partner intervened over a weak bid, but most of the 4♥ bidders claimed that the 5 level was not safe. This is not a beginner's concept and I bet many people knew about it from reading it in their comments. If an éxpert' chooses the low road, then you can feel represented when you underbid. If most experts decide to bid higher thn you, pay attention to their reasons. And I don't think results always dictate the scores in the challenge. Sometimes the experts will be very optimistic and the real hand proves to be a disappointment. Just as in real life ;) You can check the comments by Marc and me on YouTube before deciding what to bid:
