Analysis by David Loeb

The Bidding: West opens a Strong 2 Clubs . It is often profitable to interfere in a strong 2 auction because the opponents have announced they expect to make a game and have exchanged no information about their distribution. North's texture is poor. So interfering could be costly. North's 5-5 shape has trick taking potential. Few partnerships have methods to show the black suits. Interfering with a 2 overcall seems best. Over Strong2CInterference in your strong 2 auctions, it is common to use a double to show a hand willing to stop below game. West could cue bid 3 to ask if East has a spade stopper. That would be an overbid. West knows North-South have 4 quick winners in the black suits. If East doesn't have a club stopper, North-South will have no trouble beating 3NT. Bidding 3 seems best. East has a diamond fit, but has no reason to believe a game is available. West's 3 bid ends the auction.

At tables where North is silent, it is common for East to respond 2 Diamonds Waiting . West's 3 bid is forcing. Since it is difficult to judge major suit fits on this auction, some partnerships agree the uncontested auction 2-2-3M shows a strong hand with long diamonds and a 4-card major. East doesn't want to advertise a 5-card major and doesn't want to bypass 3NT. So East bids 3NT, ending the auction.

The Play in 3NT by East: Many will lead their 4th best best heart. On a red suit lead, declarer scores their 8 winners for +600. Since North is marked with spade length on the auction, South may prefer leading the Ace to look at dummy. North signals for a spade continuation. Now North has no difficult cashing the Ace and continuing clubs to beat 3NT.

The Play in 3NT by West: A low club lead allows declarer to make 3NT. On a spade lead, South wins their Ace. Dummy's JT73 suggests there is little future in spades. The killing defense is difficult to find. South must lead a low club or a spade. A club return makes it easy to beat 3NT. On a spade return, North must win their King, cash their Ace, and continue clubs to beat 3NT. At many tables, South will switch to a heart, allowing declarer to score 9 tricks.

The Play in 3: Declarer has 9 quick winners. A heart ruff in the short hand provides declarer's 10th trick.

Analysis by Lynn Berg

West opens 1. North bids 1 or passes. East passes. Now South will balance if necessary, but West won't care and will jump to 3. Nice to find partner with three trumps and a doubleton heart. Just remember to ruff a heart before drawing the third trump.
