Sorry I see somebody else already replied to the first situation

Thanks, the first half of your reply makes a lot of sense. I do not know much about 2/1 so Ill have to do a bit of reading. You didnt comment on what happens if not playing 5-card majors. Since your partner may not support hearts with what he thinks is only a 4-3 fit. Should we rather bid 1♠, or is it still best to bid 1♥. Thanks again

Consider the hand: ♠: AQJ7 ♥: AQJ98 ♦: 65 ♣: 93 In a system like Acol which alows 4 card openers, I assume that you would be forced to open 1♠ since you would not have enough strength to reverse the rebid if you open 1♥. Is this correct? How do you bid this if playing 5-card majors? If we open 1♥ we may need to reverse the rebid into 2♠ but we cannot open the spades with only 4. I assume that we really cannot open 1♣ or 1♦ in this situation since we may get into huge trouble if our partner passes especially if we are vulnerable? Im a new player, so a fundamental misunderstanding is possible.
