Late last night, I was playing in an BBO ACBL IMP Pairs game. My partner and I play very aggressive weak 2 bids nonvul, so, when I held this hand:
I had to open 2♠. The rest of the auction proceeded as shown.
It turns out that only a trump lead (with partner not playing the ♥K at trick one) will beat slam. Believe it or not, this is the full hand:
West made a "takeout" double with 55 in the pointed suits. East, needing the right normal takeout double in partner's hand to make a grand, quietly bid game.
I guess they know their limitations. Declarer made 10 tricks on a spade lead.
