We recently started playing that 1S-2D shows hearts. 1S is 11-16 with 5+ spades, 11-13 if bal. Our treatment is that 2D is either:

a) Weak with 6+ hearts
b) INV with 5 hearts
c) GF with 5+ hearts, doesn't want to relay

With 6+ hearts and INV values we bid an invitational jump shift.

After 1S-2D:
2H = NF, may be 0 hearts.
...Pass = Weak with 6+ hearts
...2S = ART GF (waiting style)
...2NT = INV with 5H
...Higher = Nat GF
2S = NF with short hearts and long spades.
...Pass = 6+ hearts weak
...2NT = 5H INV
...3S = INV
...Others = GF
2NT = Super accept of hearts
3m = Nat F1
3S = Super max nat

Do you have any tips or tricks which may be better?

We play this but only utilize A and C.

I have no idea what's best.

I play

1S-2D("5+ H"); 2H-?:

P = "7-9", 2-S6+H*
2S = "10-12", 2 S**, NF
2N+ = GF, unbal.***

* the response to 1S with "4-6", 2-S6+H is 1N (NF)
** the response to 1S with "10-12", 1-S5H is 1N (NF)
*** the response to 1S on GF hands with (5431) or less shape is 2C ("4-way"), intending to relay

I don't think you need a nf 2n bid after opener's 2s rebid.

We offload 1S-3H as strongly invitational in hearts and 1S-2C as GF relay for most GF hands with hearts.

1S-2D

2H-no fit unless minimum
.....2S-doubleton, GI
.....2N-GI
.....3m-GI,5m
.....3H-lightly invitational (less so than 1S-3H)
.....3S-GI, 3-fit
.....3N-to play, minimum GF
2S-6S, no fit
.....similar to 2H rebid
2N-2 or 3 hearts, asking with max
.....3M-GF, 5m
.....3H-6H, min
.....3S-2S, GF
.....3N or 4M-to play
