Thank you. Don't know how i overlooked that the 2 card preference would be in there as well. The 1N; 2h two step response doesn't limit my hand any more than if I started with 1s. This makes the 1N less valuable than I thought it was. If my partner "never" raises to 2 spades on 3 card support I think I start with 1s, but if partner frequently raises on 3 card support I start with 1N to make sure I avoid a 4-3 fit in spades.

I've never played F1N but I assume the sequence 1H-1N; 2m-2H is the weak raise showing app. 4-7 hcp. When I hold a hand that is only worth 1 bid I prefer to use that bid to support partner in a known major fit. If I start with 1 spade and partner bids 2m my 2 heart bid does not show real support.

One important factor that must be considered is: Will opener raise spades with 3-card support? On a routine 1 heart opener such as AJx KTxxxx KQx x I would rebid 2 spades without a second thought. The 1 spade bid has then landed you in a 4-3 fit and your only hope to get back to the 6-3 heart fit is if opps decide to balance. Even if your partnership would never raise on 3 card support, try weakening the hearts and strenghten the pointed suits in my example hand. Sometime before reaching AQx 765432 AKx x there will be a point where bidding 2 spades feels like a lesser evil then rebidding hearts.

What am I missing?? I count 5♠+2♥+1♣=8 sure tricks. Getting to 12 requires 4♦ tricks on A9853 to KJ. Playing low to the J should make 6NT on: any 3-3 split (with overtrick if finesse is on) any 4-2 split with q onside QT offside stiff T offside and with QTxxx(x) onside in can make on ♣K onside or possibly some squeese

Hasn't dummys LHO played out of turn, thus violating L44B? The ♥6 is AFAIK not a played card until declarer calls for it.
