I don't know what happened to the first time I typed this.
Assuming you forced me to bid 1♠ rather than 1♦:
1♣-1♠
2♣-3♦
3♥(4SF extras when 3N pulled)-3N
4♦-5♣(voidwood, I have 5+/5+ ♠/♦ and a heart stop, so void club very likely, this confirms)
6♦(2+Q+void, spades presumably or might have voidwooded hearts over 3♦)-P
Beginning the same way up through 3n. I would have continued 4s voidwood. It is not possible to be to play since we had an easy 3s bid earlier. East must have the heart A and/or K
for their 3n bid so we know all suits are controlled.
4s voidwood
5c 0 or 3
6d bid with a huge amount of confidence since we are missing the heart ace east must have the heart K for 3n and thus have at most a singleton club
If east had shown 1 or 4 we could have tried 6c to ask for the club K (and show all the keys aside from the spade ace) as a great way to try for a grand or (expanding out a bit) 5n to ask for the "club" king and 6c to ask for the club Q
Another question: if west had started with void Qxx Axxx AKQxxx would your bidding be the same (through 4d at least) and if so can you stop safely in 5d after the 5c voidwood with your extended replies? I like very much the 3h bid which can have great utility under a huge variety of circumstances.
Oh 100% west for bidding a grand when they are conceivably (probably actually) missing a cashing ace
