Hello,

a. In our partnership (modified polish club) I suggested to play (like Bocchi-Duboin-Club 2001) transferbids on the 1♣ opening.

1♣-1♦ =4+♥s, 7+HCP
1♣-1♥=4+♠s, 7+HCP
1♣-1♠ = 0-6 without 4cM, 0-11 otherwise, 12-16 bal. (like 1♦ before)

This occupies the first-level responses.
On the other side, 1♠ has to be forcing, so with 11-14 you have to bid 1NT and play a weak one. P has given a lot of information too, so it can get dangerous, mainly vulnerable.

Any experiences playing something like that?

b. As alternative I suggested to remove 12-16 bal. from the possibilities as responder. Then 1♠ is NF - you only can miss close games with fitting hands in the minors - and you can pass with e. g. 11-14 bal. and 4♠s.

Any experiences playing something like that?

If you agree to a) I suggested further to play raises as before, 1♥/♠ as transferbid shows 11-14 bal. with 3cardsupport (again stolen from Bocchi-Duboin ). The other opportunity is to play the transfer with 4 card support and raise only if you are stronger than 11-14; of course after new evaluating your hand after finding the fit.

Any hints for me?

I don't think this is a good structure. If you want to have opener as declarer I suggest

1♥ = 7+, 4+♠
1♠ = 7+, 4+♥

Since no one responds here is why:

After 1♣ - 1♠ (possibly negative) when both players are weak, you are in BIG trouble!
Also since the 1♠ bid has many possibilities you are preempting yourself...
