Opps overcall or double our 2♣ opening bid

If opps double or overcall (without jumping), we bid as if the opening was W2♦, however we do not preempt beyond 3♦. RE's only forcing bid is cue, all other bids are natural and NF. Double is for penalty.

OP's bids (except 3♦, which confirms W2♦) are natural and confirm S2♣. Bids 3NT and higher are system on. After 2♣ - (x) - pass - (pass) a bid shows S2♣ min, rdbl and later bid shows S2♣ max.

If opps jump overcall, we bid as if the opening was S2♣; pass promises a ST, dbl is for T/O and denies a ST.
