:-0 Stacking (( ﾟдﾟ)ﾎﾟｶｰﾝ積み) is one of the TD Attack variant openers, where the first bag can always be stacked, the second bag can always be stacked without softdrop except for the T-piece, and from either of the two routes. A high probability 8-lines PC is possible. This opener was invented by Yuu.
The "：" in the page name should be one-byte characters(":"), but for the convenience of page creation, we have used double-byte characters.

L>J right roof(J-hold)
|
J>L left roof(L-hold)

Stack them like this. If the L piece is earlier than the J piece, the left stack is used; if the opposite, the right stack is used. The setup rate is 66.67% on one side and 100.00% on both sides.
The description from here is right roof(L>J).
2nd bag
TST is always possible; if the O piece is earlier than the J piece, use the left stacking method; if the opposite, use the right stacking method. there is no softdrop except for the T piece.
