COVERY YOUR ASS

This is a Romanovsky variation. Place 1 unit on 9 consecutive corners (they will be overlapping) in either the 1st and 2nd columns, or the 2nd and 3rd columns. Whichever is the open column, place 5 units on that column bet. The 2 edge corner bets on either end are partial losses. Corner bets on the inside of the edges pay 4 units. If you hit the covered column, it pays 1 unit.

Progressions: Standard 2x martingale until recovery.
