MDF

Work in progress

MDF (Mini Double Fractal) is an opener created by benmuga which makes a TSM or a 1 line skim followed up by a TSD and a Perfect Clear with I J or L ending. If PC is not possible then starting making a fractal, the concept of it is that is very likely you will have the 2 T pieces

MDF can be used in various piece patterns always following the next rules:

1.- If L is used first, J must be used after Z.

2.- if Z is used first, S must be used after L.

Those rules applies not exactly right after "Z" or "L" are placed but they must follow that order independent of the other pieces on the same bag, and both rules are expected to be on different bags.

Some tips to memorize the opener easily and have a higher success on MDF build are:

1.- DAS O all the way to one of the walls

2.- If O is placed on the right wall, Z comes next to O

3.- With the example of tip 2, on the left wall L and S comes together

4.- Always start building what is next O piece. (Z and J, or S and L if mirrored).

First bag

Route 1:

First Bag with PC end

Route 1: (TSD into PC end with I piece)

Route 2: (TSD into PC end with J piece) (Also works for L if the opener is mirrored)

Second bag if PC is not available

Route 1:

Route 2:

Route 3:

Route 4:

Continuation

King crimson

4-Wide

6-3

TSS instead of finishing with TSD

In case if T is the first piece you need to place because you have an I piece right after, wasting T would be the only option to make the opener, and the only position for the opener that it have is placing the piece right where it spawns or one space to the right, depending on the pieces after I. After this you must hold I and follow the rules above.
