A Blind bid is committing to a number before you look at your hand. It doubles the payout on a make and the penalty on a miss. When you're desperate, it's your best comeback tool. When you're comfortable, it's a way to blow a lead.
How the Blind 6 works
Before the deal, when your team is far enough behind (typically 100+ points behind, house rules vary), you can call a Blind 6 — a promise to take 6 books without looking at your cards.
Make it: +120 points instead of the standard +60. Miss it: −120 instead of −60. Same math as a Blind Nil at the higher scale — bigger swing both directions.
When it's the right call
When you're behind by enough that a normal hand won't catch you up in time. If a regular 4-book bid at 40 points won't close the gap, a Blind 6 at 120 might.
When your partner is strong and confident. Blind 6 is a team commitment — your partner needs to be ready to over-cover and take extras. Weak partner + Blind 6 = disaster.
When to skip it
When you're only slightly behind. The math on a Blind 6 miss (−120) is worse than the math on winning slowly with regular bids. Don't force it.
When the opponents are close to game. A Blind 6 miss can end the game right there — they only need enough points to reach the target and your set puts them there. Better to bid safe and hope to make and set them.
