Your 2♣ opening probably has a different meaning from the OP though. Would you open it 2♣ in Benji, SEF or Forum D? Or 2♥ playing Strong 2s? Notice here also how the methods played their part - if 2♥ was an immediate negative then the pair can play the hand there. If 2NT was the second negative after 2♦, the pair could have played 3♣. Only with the negatives being 2♦+3♣ does the pair end up in 3♥ on a 5-1 fit. There are certainly some system lessons to be learnt here but precisely which ones you take away are a matter of conjecture.
We too play any rebid other than 2NT (or Kokish 2NT) as game forcing, so yes the 2
♣ meaning is different.
I don't have a strong 2
♥ bid, haven't much experience of playing one and I've seen different ways of playing it too. The local old ladies play that a 2NT response is a non-forcing negative and while passing that might not be a disaster (1 down on this layout, like 3
♥), I might as well have opened 2NT in the first place (RA and partner permitting). In the 4-card majors I was taught, the 2NT response was effectively forcing and just denied 5-card
♠ or a well honoured minor: now my 3
♣ rebid would be forcing too, so we can't stop below 3
♥ bid by responder and risk going higher. Happy to have a different system with problems of its own.
