2♥ - 2♠ - forcing or non-forcing/constructive?
My partner and I are unsure about what our agreement should be.
NoFear and Andrew Robson recommend that it should be played as constructive non-forcing, showing no interest in hearts, around 11-15 points and a good 6 card spade suit. Other respected sources recommend playing it as forcing for one round. All of them acknowledge that both approaches are valid.

Comments much appreciated.

The less tightly defined your weak 2, the better constructive NF becomes, if it's a 5 point range and decent quality 6 card suit, either approach is valid, if you get any wider than that, I'd go with constructive NF.

One thing about this particular sequence is that there is room for a forcing 2H-3S bid. The question, and legitimate IMO, is do you want to play 2S-3H and 2H-2S the same as there is no room for a jump force in hearts or solve it by agreeing that 3-level bids are forcing but 2H-2S is not.

The first qualifier about whether a new suit is forcing responding to a weak 2 should be "by an unpassed hand".

I agree with cyberyeti that if you're going to bid weak 2's aggressively in 1st or 2nd seat, then non-forcing is probably better.

OTOH, if you decide to play reasonably disciplined weak 2's in 1st and 2nd seat, then maybe forcing should be considered. 2 ♥ - 2 ♠ forcing let's you explore for a possible ♠ fit without getting too high.

If new suits are non forcing, then the only way to force the weak 2 bidder is via a 2 NT response. Over weak 2 bidder's rebid, responder will have to decide whether or not to show their suit at the 3 level (or possibly at the 4 level).

If you're going to play forcing, you can also invert the meanings of 2♠/2N.

If your opening promises 6, play it as forcing. Especially if the opening promises a decent suit.

If you sometimes open on 5 cards, play it as nf.
