I don't like the look of the Deschapelles Oscillation caused by that last move. Consulting my Federov Tables suggests that the best way to return some balance to the game is to march boldly to Blackwall and place a mauve podume into play. This I now do.
Alas, this edging about has bunched up so finely that according to my Dominant Lane Axis Graphs, I could unravel the entire structure and enter the game with a single Reverse Archipelago Pin straight across the third bilateral to Mile End.
