Reverse Flannery Convention

The Reverse Flannery convention was invented to solve the bidding problems when holding 5♠ and 4 opposite a 1 minor opener. Playing the 2 and 2♠ jump bids as conventional, we can describe these hands with a single bid. This can be crucial in certain situations where a fit could be not found after a ♠ bid on the one level. Take this example for instance:

If we play 2 as non-forcing then we would have to bid 3 with any GF hand including 54, 55, 64 in the majors. If we play 2 as forcing, then we have to bid 2♠ now and we might not find our heart fit.

Furthermore, we can use the 2NT over these jump bids as a relay, and this way the contract can be played from the opener's hand sometimes, which can advantageous. This a wonderful convention, my suggestion is that everybody should play it!

Without further ado, the convention is as follows. The 1m-2 shows 5♠ + 4+,weak hand max 9 bad HCP, with the following continuation:

1m 2
?
PWe are weak, and  is tolerable (3+ ) 2♠
2♠We are weak, and ♠ is tolerable (3+ ♠)
2NTLimit+ relay, asking
3♣5♠ + 4 weak, to that 3 is asking for 4th suit stopper
35♠ + 4 strong, GF, natural bids after this
35♠ + 5(+) , weak, natural bids after this
3♠5♠ + 5 strong, GF, natural bids after this
3♣NAT, even after 1 opening
3mTo play, opener doesn't want to play a major suit
34th suit GF after a 1♣ opening, opener's only interested in stopper
3/3♠Preemptive, bid 2NT with limit + hands
3NTTo play, we've arrived partner!

And 1m-2♠ is exactly 5♠, exactly 4 and 9-11 points, with the following continuation:
