if bidding is allowed by partnership agreement, 2 Spade had been fine.
It has not been allowed in my regular partnership so I had passed.

After the bidding went
2 ♥ pass 4 ♥ pass pass I had bid 4 Spade.

The N hand isn't that great. The Q♥ is garbage and the Q♠ probably isn't worth anything either. Even the 5th trump doesnt help that much.

I wouldn't make a slam try, much less bid 6. Would you if you held: Axxx xxx Axxxx x? Because that about what the hand evaluates to.

I agree with Phil 100%. Overcalling might have been a 1% overbid (I think it's actually 0%) but punting 6 is a hundred times worse.

Late to this post.

Obvious 2♠ overcall.
Obvious balance over 2♥ - p - 3/4♥ - p - p - p - I'd bid 4♠ over 3 and 4♥.

6♠ by partner is a huge overbid - I'd never even think of bidding slam. Inviting slam is a possibility though.

Thanks all for the answers.
Let me add 2 comments in defence of my partner:
- We don't play together for that long. I'm the more aggresive bidder. Partner did certainly expect more from my 2S bid.
- We didn't have an agreement on how to invite (and 4NT would have been for the minors). So it seemed like a guess between 4 and 6S for him
...We kind of agreed some weeks ago that if opps compete like here then 5S would have asked for a H control to go to 6S. Not important her, but seems a better bid then 6S. (hmm, this last comment is not part of the 2 comments in defence of my partner ).

6♠ is what you deserved for missbiding , but actually reversed minors would make it a decent slam.

I would pass and reopen with 4♠
