Z-Spin Tutorial (The Troublesome Red Tetrimino)

Case 1:  (Z spin, hit  Z then Z) This needs a pre-rotation which means the tetrimino needs a specific rotation before you soft drop. If you accidentally hit clockwise first instead of counter clockwise, do this:

                                            1. You accidentally hit clockwise "up arrow key"

                                            2. Hit "z" twice or counterclockwise 2 times

                                            3. Soft Drop

                                            4. Counterclockwise "z"

Case 2: (Opposite of Case 1) This type of situation happen sometimes  so this might come in handy. If you happen to hit counterclockwise first instead of clockwise, do this:

                                            1. You accidentally hit counterclockwise "z"

                                            2. Hit clockwise twice or up arrow key 2 times

                                            3. Soft Drop

                                            4. Clockwise "up arrow key"

Case 3: Useful at times..
