Playing Standard American but not 2/1 Game Force. As Responder when I bid a suit at 2 Level, that is not a jump shift and when the opponents have passed in between, does bidding the suit show 4 or 5 of that suit? I know bidding 2 hearts always shows 5 due to the convention of bidding the lowest four card suit.

Examples are

1 Pass 2

1 Pass 2

For the suit below yours, the key to understanding is always the (4333) hand. 1 - 2 shows 5 because with 3433 the correct response is 2. It has nothing to do with bidding the lowest 4 card suit.

After a 1 opening, we would respond 2 with a 3334 hand. If the 1 opening shows 4+ then this is typically the only shape where the 2 response is not 5+. If 1 is 3+ then you might also make the call with (32)44.

After a 4+ 1 opening, we would always respond 2 with a 3343 hand of suitable strength. If 1 promises 5+ then we could in theory always raise with 3 and therefore make 2 5+. But most pairs prefer to differentiate more clearly between 3 and 4 hearts rather than 4 and 5 diamonds and therefore will respond 2 on many of those 3343 hands.

The system you play is designed to show strength before length so your first duty is to describe your strength to your partner which means sometimes bidding 4-card or even occasionally a 3-card minor suit.

As opener, you should not raise responder’s minor suit without 4-card support.

2 could even be a 3-card suit in some cases

Do remember that a lot of the 4333 hands that can't just raise bid the appropriate number of NT.

Playing Standard American, 1 is 5. So the choice with 4333 is raise or NT (almost always raise). 3=2=4=4 might bid 2 (I'd probably bid 2 always, but bridge always always means "except when it's clearly wrong"), but I'd expect 5 for 1-2.

1-2 is an awful sequence in any system, but 5cM in particular. There are page-long conventions specifically for this auction (which I don't play, but you get the point).
