there is a fairly obvious 6♣ but I (sitting W) was very lucky to get there without mishap. Partner opened 1♠ and I responded 2♣. Partner responded 4♣ - not the best bid, I think a splinter 4♦ would have been better, but we weren't playing splinters.
Anyway I launched into 4NT 0314 without thinking too much about it. I'd clean forgotten the old advice - 'beware of Blackwood if in clubs!' What if partner had responded 5♦ showing 1/4? I probably didn't deserve to get away with it. Anyway it ended up 5♥ - 6♣.
Other options (again not on our card) would have been for me to cue-bid 4♥ and if partner bids 4♠, cue-bid 5♠. But I still need to find out about the diamonds. I'm sure others will suggest something better!
