Don't need forcing bids later: 1♥ - 1♠ - 2♥ - 6♥ :) But... if you want forcing bids they're not hard to find. After 1♥ - 1♠ - 2♥, then 3♦, 3♣, 4 NT and 4♦(available if you cuebid 2nd round controls) are forcing. Bidding 2♣ on that may have established a GF, but it's also established a mess. By bidding 1♠ you get more room for exploring strain and level. If partner rebids 1NT, it's more likely you belong in NT (and you can still force by using XY-NT or the like...) If partner rebids 2♥, you've found a fit at the 2-level. And another bonus: You don't need to lie about ♣/♠ length and strength like you do when bidding 2♣ and rebidding ♠... In my partnership it might have gone like the first sequence of my post - not the craziest of punts. An alternative: 1♥ - 1♠ - 2♥ - 4♦ (denies ♣-control) - 4♥ - 4♠ - 4NT etc.
