**Lesson 6: Increasing the fifth column**

As mentioned in the previous chapter, let's talk about rising that fifth column.

The T can only be moved to both sides if the 5^{th} column is the highest. |

The Z and O can be moved to both sides if the 5^{th} or 6^{th} column is the highest.Be careful about using IRS if it's the 6 ^{th} |

The S can be moved to both sides if the 4^{th} or 5^{th} column is the highest.Be sure to use IRS if it's the 4 ^{th} |

The J and L can be moved to both sides if the 4^{th}, 5^{th} or 6^{th} column is the highest.IRS may be needed to give yourself opportunity for movement. |

The I block can be move if the highest column is anywhere between the 4^{th} and 7^{th}. |

In other words, the fifth columns should always be the highest. This allows for the most movement.

In 5 of the 7 blocks the fifth column is ideal.

Here are some techniques to get the fifth column as the highest one.

L upwards: If you use irs on the J and L blocks, they will land perfectly, given the stack is flat. |

Z down the stairs: If you move the S and Z blocks one column to the left or right, they will be placed ideally for 20G. |

5^{th} column I:The I block has to rotated and moved one column to the left. Sometimes you need to do this in reverse order! |

The T just has to be rotated twice. The O already lands perfectly and can be moved one space to the left if desired. |
