Blackout Sucks

The default "expert" Australian arrangement is Blackout over Reverses.

In recent history when it has come up ,either when we bid it or the
opponents did, none of the auctions were impressive. In the sense, the
final contract invariably had a big guess element to it.
The post non-blackout GF continuations didnt seem to address the key
issues very well.

Thats my impression. Hence the title.

Am interested in any alternate schemes devised over reverses. Or for a
more detailed account of Blackout than "Cheaper of 4th suit/2NT is
NF ; all else GF".

Interested in later round actions and auctions......
