Gambling 3NT

 

Open 3NT when you have a solid seven-card minor, possibly eight. Solid means at least: AKQxxxx (seven cards) or AKJxxxxx (eight cards). You cannot hold an outside ace or king for this bid.

 

Purpose is to take away bidding room from opponents, or help partner decide on going to game or slam, or make 3NT with a favorable lead and a couple of tricks from partner.

Four Clubs - A 4C overcall shows hearts and a minor (this is actually the ďAstroĒ convention).

Four Hearts - A 4H overcall shows spades and another suit.

All Other Suit Bids - All other suit bids are natural in meaning

Opening Leads - When a Gambling 3NT opening becomes the final contract, the opening leader should try to lead a winning card. The purpose is to retain the lead, so as to see the dummy and partnerís signal. This way, the best attack can be found.

[ 3NT   Pass   Pass   Pass .....  Lead your AH. You will then be able to shift (probably to spades) if hearts are stopped by the enemy. Notice that a spade lead, if wrong, gives you no second chance.
