We play Landy so have no way of showing a major/minor two suiter over 1NT. That was a bottom for missing a spade contract, never mind a spade game.
I would have liked to have made a takeout double on the second round but did not have that agreement with partner and where that would go no-one knows. I considered bidding 2♠ on the second round but felt with a flimsy suit I could be walking into a world of pain given partner has failed to say anything and could be weak. I hoped partner might find a bid in the passout seat with some values knowing I am strong. Unfortunately partner didn't find a bid and has a perfect hand for me in a spade contract.
On a second note with the North hand, how do you defend passively holding unguarded honors in three suits over opener and holding a singleton trump. I started off with the trump lead hoping that was the least of evils, fortunately it didn't finesse partner this time, but I am getting in quite frequently and there will come a point where I don't know how to position the minor suit honor cards, so don't know how to get off lead whilst minimising giving a trick by either opening a frozen suit or leading up to declarer's broken honors, and does declarer have four clubs and the ability to set up the fourth one for a discard (not this time)?
