PArtner had this:

♠Kxxx
♥Kx
♦A9xx
♣Kxx

He colaborated after I splintered and we got easilly to slam in spades, but collaborating after splitner is far from clear IMO.

Is it such a great slam, don't you need 2 3-2 breaks.

Only trumps, you can ruff a heart and a diamond in opener's hand.

The small loss of 2♦ vs 2♣ is made up with savings on INV Hands.

Only if you play 2♣ GF which I don't

I disagree. I play 2♣ as GF (well, almost) and 2♦ as multi-invite (With Opener's rebids being P/C except for 2N, which is a GF relay). The latter is very easy to play and doesn't seem to give me any problems on invitational hands. What I lose is the ability to stop in 2♦, but I don't care.

The situation is different after 1♣-1♦, playing Walsh, because then responder cannot have weak hand and 4 cd major. You can't miss 4-4 major fit opposite a weak responder in that case. The same is not true after 1♣-1♥ or 1♦-1♥. There are no "Walsh" inferences here, you misread Hardy because he is not in the "always rebid 1nt when balanced" camp. He only does that after 1♣-1♦.

There are different styles, all have their advocates:
1. Always bid 1♠
2. Always bid 1nt.
3. Bid 1♠ with 4432, but rebid 1nt with 4333
4. Make judgement call based on suit quality/shape/honor placement.

I'm in the 4.) camp.

A very good way to avoid XYZ problems (almost all) is to play weak NT 12-14. This also has the benefit of terrorizing the opponents.
