ABDADA (or Jamboree) will probably give you the best performance for a recursive search.

Jamboree may be one of the better performers but it is not same as ABDADA. It is more closer to YBW than is to ABDADA. The latter relies on the hashtable for parallel speed up. It may perform really well sometimes. Think of embarassingly parallel algorithms such as randomized best-first RBFM and UCT etc. However YBW performs much better for inherently sequential algorithms like alpha-beta.

Suggestion to the OP: Why not implement YBW with a message passing model ?
