That's not at all what I meant. Give me a little credit. Your 8HCP are may be concentrated in your suits, but it's still 8 HCP. Or put another way, out of 20 HCP in your suits, you have less than half. You have no idea where the ace and king of spades are. If you pass you will certainly lose a double game swing sometimes, but if you bid you're going to go -800 (or more) in some cases where the opponents are headed down. The state of the match might make a difference. If you think you're behind, the argument for bidding becomes stronger. But it's an odds-off gamble. If you have confidence in your team, a pass is better.
