This week, we learned a Tetris opening: the DT cannon, also known as the Double Triple cannon. The setup utilizes the t-spin, the SRS spin that gives you bonus points and damage when executed correctly. Many people use the opening because very consistent and has many possible continuations after finishing. At first, we couldn’t really get the hang of it but after a few tries and guidance from Tommy, we were able to perform it.
Start by placing the O piece all the way on the left. This will be part of the DT Base. Next, make either of these formations. Both work, just that the one with LS on the left is slightly faster.
From here, the quickest and usually most efficient way to build the DT Formation is like so. This is the most efficient because it uses the 7-bag and effectively uses your first 14 pieces, which should nearly guarantee this setup.
After this, simply T-Spin twice using the left. When T-Spinning, be sure to hold the soft drop button or else the T might get stuck in the wrong position. If you need help, you can take a look at the video guide. After this, you are left with either a side 4 wide or a Tetris well. I prefer the Tetris well but you can do whatever. Common continuations include: DT-King Crimson, DT-S4W, DT-2-7 and more. DT-KC is usually inconsistent and S4W requires some skill in both rotations and predictions. I recommend the Tetris well or 2-7 stacking.
