This evening I have posted at the kingsrow web site 5 new draws for the Black Hole. These include at least one new draw against each of white's three main attacks. AFAIK this is new play that has not been published before. Please correct me if I'm wrong. Follow this link for more details, and also to download an opening book file that you can use with kingsrow to play out these draws. Here is an excerpt from my web site:

Of course I'm not recommending that you run out and play these lines at your next tournament :-) Since they were not uncovered by the book generators using 8-piece programs, they're probably more difficult to defend crossboard than the draws that have been previously published. Still it's interesting to know that there are all these ways to draw the Black Hole. After all, it was not until 2002 that this opening was even known to be a draw at all. Before then it was considered to be a loss for black. When I did the first expansion of this in 2001/2002, it took several months of computing. At that time only one drawing line could be found against each of the three primary white attacks. Later on, with stronger programs and 8-piece dbs, 12-16 was added as a second sound defense to white's 25-22, to go along with 7-10. I am quite surprised to find that there are now so many new ways to draw this opening.
