Polish club: 1♣ - 1♠ (7+, 4+♠); 2N (18-22ish balanced with 2♠) - 3N (yes that 2N rebid sucks, but 2♦ is artificial, 18+ 3+♠ here).

Here is the sim:

$ redeal -S '65 AKT6 KQ965 AK' --accept 'return deal.north.shape == [5, 3, 1, 4] and 4 <= deal.north.qp <= 5' --init 'self.HS = self.NS = self.HN = self.NN = 0' --do 'self.HS += deal.dd_score("4HS") > 0; self.HN += deal.dd_score("4HN") > 0; self.NS += deal.dd_score("3NS") > 0; self.NN += deal.dd_score("3NN") > 0'\
--final 'print(self.HS, self.HN, self.NS, self.NN)' -n1000
811 815 867 874

So double dummy 3N (from either side) is ~5% better than 4♥.

thanks very much!

1♣ - 1N - 8+, 5+ spades
2♣ - 2♦ - 0-2 controls
2N - 3N - Handover control, partner knows about spades, did not seek heart fit.

IMprecision has several reasonable auctions to the same contract:

IMPs:

1♣ - 1♥ (strong, 4+♠ with 5+hcp and 2-6RP)
1♠ - 2♣ (relay, 4+♣)
2♦ - 3♦ (GF relay, 5314)
3NT - Pass (to play, responder can in principle pull with something like 13 hcp)

MPs:

1♣ - 1♥ (strong, 4+♠ with 5+hcp and 2-6RP)
1NT - 2♥ (17-19 less than 3♠ natural NF, transfer)
2♠ - 2NT (accept transfer, GF with 4+♣)
3♣ - 3♠ (relay, 5314)
3NT - Pass

Basically opener must decide whether to GF with this 19-count; I tend to GF at IMPs but not at MPs. It's possible that responder could just blast 3NT over 1NT on the second auction (since we know there's no spade fit and we don't really have enough stuff for slam) but I gave the longer auction because it's maybe a bit more interesting.

Also very close for me on this one, but I think I will not force to game with South's hand because of small doubleton spades and doubleton AK clubs (I would have forced to game with Kx AKTx KQ9xx Ax, for example). Also, I will not blast to 3NT directly as there is a way to show the precise shape and that can help find the best game, maybe in a 5-2♠ or 4-3♥. Note that the 1NT rebid usually denies 5♥ so there is little risk of missing a 5-3♥ fit for Adam's suggestion to blast to 3NT.

I wish I was more confident of how this one gets bid in Unassuming Club (I have just had a partner ask to play it with me, and we are only slowly expanding beyond the online notes):

1C-1S
2C(19+ any)-2S(natural, 6-9 or 13+)
3D(natural)-3NT

I am not sure the 2S bid is right. The alternatives all seem to lead to 3NT. I am a bit disappointed that the hearts never entered the auction, though if there were a 4-4 fit, responder would bid 3H over 3D.

I would have a boring auction:

1♣-1♥ (spades, GF)
2NT (20-21 or so)-3♥ (retransfer)
3♠-3NT

Possibly I would downgrade it, and bid 1NT (good 16 to 19) given that we're in a GF already. Same basic auction, though, as North is on a minimum w/no fit.

Does North have an alternative way of bidding this with 6 spades? If you gave North the club stopper instead of South, would you be forced to bypass 3NT?

3♠ instead of 2♠ would generally show 6.
and I'm not sure about your second question.

[Zelandakh]

My second question relates to, say:
♠QT932 ♥983 ♦J ♣AK98
opposite
♠K4 ♥AKT6 ♦AKQ96 ♣65

After
P - 1♣;
1♠ - 1NT;
2♦ - 2♠;
3♥ - 3♠,
South is presumably not keen to bid 3NT. I was asking if you have some away around this (quite common) issue. One simple solution is just to bid 3NT with the North hand, thus hiding the 5th spade. Another one would be for South to bid 2NT instead of 3♥, but perhaps you need this for something else.

[Lord Molyb]

North would probably bid 3NT with that.

[CamHenry]

Unnamed Homebrew Diamond:

If S treats the hand as balanced:
1♦-1♠ 16+, excluding GF/8+ almost any
1N-2♥ 16-19 balanced/transfer
2♠-3N Denies 4-card support/Choice of games
end

If S shows shape:
1♦-1♠ 16+, excluding GF/8+ almost any
2♠-2N Single-suited ♣ OR both reds OR short ♠/Relay
3♦-3♥ Both reds, better ♦/♥ preference
3♠-3N Waiting bid/Suggestion of contract

It's possible that N would decide to just bid 3NT instead of suggesting the ♥ fit, and it's possible that S would end up bidding 4♥ on this start.
