Overstacking can be very dangerous against an aggressive opponent. If a player is not able to get down to the garbage efficiently, he'll be overwhelmed by garbage.

Fundamental

In this situation, a player overstacks and takes longer to get down to the garbage.

Naive gravity

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.
