Hi all!
Playing MINI NT (10-12),
1) what scheme do you think is best to handle the following responder's hands ?
- slammish one suiters
- invitational one suiters
- slammish 2 suiters
- invitational two suiters
- weak 2 suiters.
- (As we are about that, also GF 1/2 suiters could be discussed...

)
If the answer may be too long here, any pointer to the right sources to study will be greatly appreciated
2) Some sources suggest playing 2-way stayman, and the advantages seem quite clear.
Yet, playing miniNT, I like safety, and giving up the weak 2D signoff worries me a bit.
I would appreciate opinion on this by all people who have experienced miniNT.
3) I am having a little debate with one of my partners who would like to keep transfers on also over miniNT. This is related to point 1) above, as he argues that weak and strong 2-suiters by responder are easier to describe.
All the sources I am studying recommend against that, what is your comment ?
Thanks all!!!

I am a Keri convert.
1. In order:
A. Keri has a cool low-level key card ask with real good suits: 2
♠ forces 2N (initially a quantitative range ask), but then a pull to a suit is RKCB in that suit. Otherwise, the auctions get a little bulky, having to go through 1N-2
♣-2
♦-2N-3x to show the suit.
B. For the minors start with 2
♣, then 3 of a minor after the forced 2
♦. For the majors, just jump to 3 of the major initially.
C. For a 5-4 (Jacoby), start with a transfer, then 2N shows a 5-4. Responses get complicated from there. For a 5-5, just transfer and bid the second suit.
D. Keri isn't as well equipped here, but you do get the option of playing the major at the 2 level.
E. Just transfer. Sometimes the opponents balance and give you the chance to show your second suit
F. (Not mentioned) - Keri has a great splinter structure with 3
♣ through 3
♠ that allows you to show 5440's and 4441's with a lot of efficiency.
2. In my other partnership we limp along with 2-way stayman, but we reverse the 2
♥ and 2
♠ responses allowing responder to initiate a control ask a la Precision.
Obviously with Keri getting out in 2
♦ isn't a problem. Here's another scheme I used to play. Its a version of what the Italians used to call "Gladiator":
2
♣ - Transfer to 2
♦. Signoff in any suit, or quant 2N raise.
2
♦ - Non-forcing Stayman
2
♥ / 2
♠ = At least 5 in suit. Opener responds Ogust style.
3. Using a transfer response to a mini-NT isn't a big deal. While you occasionally wrong side the contract, sometimes you actually right-side it; the Q's and J's in the weak hand end up getting led up to. The extra flexibility in describing the varying hands is worth it.
