Cross Chain Reaction is the same as Chain Reaction [A1,C1], except that the Very Centers Diagonal Pass Thru with the diagonally-facing (instead of a Pass Thru with the directly-facing) Outside dancer. EN: 70

Hint: Those doing the Diagonal Pass Thru should point at each other before moving. Outside dancers not doing the Diagonal Pass Thru should not move until an original Center dancer appears by their side. Should you be an Outside dancer and prematurely turn in anticipation of the Hinge you will likely throw yourself and others out of position. EN: 80
