Battling the Dozens

[atlantis]

Sharing again a single dozen progressive attack idea which I play sometimes if anybody cares to check it out or try this approach for a change...
(Thanks to BuffaloWizard)

Note: Patience and persistence required.

Atlantis,
Always love to read methods geared toward single dozens (and single columns).

Good that you "bumped" this topic up -- thanks.
