== Non-overstacking Construction ==
== General ==
Overstacking can be very dangerous against an agressive opponent. If a player is not able to get down to the garbage efficiently, he'll be overwhelmed by garbage.
*[[Non-overstacking construction]]
 
*[[Back-to-Back Chaining Methods]]
In this situation, a player overstacks and takes longer to get down to the garbage.

With the same sequence of pieces, a player can opt to switch the position of the T and the J, resulting in a clean opening for the garbage.

=== Towering ===
When facing an ever changing system of garbage, often, a player has to make the field uneven in height to avoid overstacking.

Be wary when towering because it's not always productive. If a player is not careful, he may end up severely decreasing his options in piece placement.

=== Alternative Line Clear ===
== Timing ==
 
== Back-to-Back Chaining ==


=== Tetris ===
=== Offensive ===
A player should be aggressive when the opportunity arises. Do not sit and counter garbage. Let yourself receive garbage and send it back. You want to send the most garbage as possible. Often, it's better to tetris after the opponent because they will not be able to counteract the garbage, either accidentally or intentionally.


=== T-Spin Single ===
If you have a chance to BtB in a short time period, don't pass it up. The more time you give your opponent between a BtB, the more likely he will have formed a plan for the upcoming garbage.
T-Spin Singles are the easiest to spot and to exploit in multiplayer. Not utilizing them will only put you at a disadvantage against an opponent who does.

=== Defensive ===

When nearing a top out, counter the garbage as best as you can. Your opponent will not recieve extra ammunition and will have to build his own tetrises. Do not waste time making many singles. Most of all, remember not to overstack.

Overhang

When plagued by an unfortunate sequence of next pieces, an overhang is another form of a scapegoat.

Timing

Offensive

A player should be aggressive when the opportunity arises. Do not sit and counter garbage. Let yourself receive garbage and send it back. You want to send the most garbage as possible. Often, it's better to tetris after the opponent because they will not be able to counteract the garbage, either accidentally or intentionally.

If you have a chance to BtB in a short time period, don't pass it up. The more time you give your opponent between a BtB, the more likely he will have formed a plan for the upcoming garbage.

Defensive

When nearing a top out, counter the garbage as best as you can. Your opponent will not recieve extra ammunition and will have to build his own tetrises. Do not waste time making many singles. Most of all, remember not to overstack.
