2♣ was a strong Acol two in a suit (8 playing trick hand) or 22-23 HCP balanced.
I didn't know what to do over 2♥ so decided to pass and let partner clarify her hand. Unfortunately I got endplayed in the bidding. 3♠ was the best thing I could think of, raised to game, three down. We should be in 3NT.
This was played on RealBridge and for some reason on this round I couldn't see or hear my RHO and vice versa, so my partner decided to do the explanation of the 3♥ for me (yes I know it is not right, I could have communicated through LHO) and she explained 3♥ as forcing me to bid.
I did think of doubling instead of passing, but didn't know how partner would take that and it is not clear where the auction will go. Maybe we need some system after interference of a strong 2 bid like pass = 0-4 HCP, double=5-7 HCP, something else = 8+ HCP. What do you think?

Over South's 2♥, I agree with West's Pass. For East I rank:
1. 2N = NAT 22-23. Quite descriptive
2. 3♦ = G/F Exaggerates the ♦s
3. DBL = T/O but partner will expect more ♠s
