Change of Heart is now up.

See http://www.bridgematters.com/coh.pdf

At first a strong heart opening seems silly, but it has key advantages if done with a restricted set of hand types, the two primary ones being 15+ with hearts and 17-19 balanced. 14 or less with hearts open on the two level to try to cut down on spade overcalls by the opponents.

Since 17-19 balanced can be handled via 1H, there is lots of room for fun stuff. One could set up a system like:

1NT: 10-12
1C: Clubs or 15-16 balanced
1D: Diamonds or 13-14 balanced

or something dangerous like:

1NT: 11-13
1C: Clubs or 14-16 balanced
1D: Diamonds or 8-10 balanced

Flip the 11-13 and 14-16 when vulnerable but keep opening those 8-10s!
