and the sequence starts 1♥ 2♥ (you dont play 1♥ 1NT as F1, so 2♥ is 6-9)

I like 2NT, aiming for 3N.

Postmortem : if you bid 4♥ you reached a noplay game facing the two minor queens and the ♠K. That's why my pard did.

I think 4♥ is a hasty bid because :

• if your p isn't able to bid 4♥ on a trial bid, I doubt you can make 4 ;
  
• If on 2NT your p bids 3NT, your are probably in the best game with your 2 "useless" minor jacks.

Come to think about it, even 10xxx xxx Axxx Ax isn't enough to make 4♥ (not that I suggest bidding 3NT/2NT on this hand)

In the postmortem, my P told me he bid it because :

• He thought other table would bid it (the poll shows it's OK)
  
• We were "the stronger" team, and if the game was on because of tricky cardplay, or misdefence, he wanted to be in game ;

I still think that 2NT is the RIGHT bid because you need to explore for 3NT.
