In general, what is the supposed advantage of such strong diamond systems as opposed to strong club systems, or sttandard? It seems like a strong diamond system is nothing more than a standard precision 1C with a nebulous 1D but with 1D and 1C reversed and slightly different point ranges for the various opening bids. am I missing something here? --
I've always thought the aim of strong ♦
systems was to be very aggressive by using extremely light and descriptive 1M/2m openings (around 8-12). These are very common and allow for heavy preemption. It's also the range strong pass systems use.
Every intermediate hand is put into 1♣
. The biggest benefit of using a nebulous 1♣
instead of a nebulous 1♦
is that you can recycle your entire system after the sequence 1♣
-... (1M/1NT/2m = same as opening, but a bit stronger) which is impossible after a 1♦
opening. That's in an ideal world where opps don't intervene ofcourse.
As a result you up your strong range (say 18+) and put it in 1♦
. Upping the range covers for the lost space compared to a strong ♣
opening and keeps your 1♣
range small enough and doesn't make it too small, a nice balance.
Imo this approach respects some very good principles, and it looks like it's an attempt to replace strong pass systems. The 8-12 range covers around 1/3 of all hands. Every stronger hand is opened nebulous (you have 2 ranges, a strong pass system has only 1 range but stays lower).
When you're planning on playing 1M around 11-15HCP and a wide ranging nebulous 1m opening, I'd definitely advise to play strong ♣
. Playing a 16+ strong ♣
system is already hard enough, no reason to make it even harder by playing a 16+ strong ♦
system imo. And even by doing so, you don't use the advantages of the nebulous 1♣
opening to their full extend.
