I. IntroductionI wanted to write this guide because after watching many people play tetris, I see them playing incorrectly with openers, and some people do not use openers. I hope many of you find this helpful to improve your early game.
II. What is an opener?An opener would be your initial approach to the initial bag(s) of pieces you get. Openers can vary in length, from quick t-spin double approaches to long combo starts. Many people who do not use openers will most likely use a tetris opener by default (stacking for a single tetris or a b2b tetris)
III. Why are openers important?Openers are unique to the rest of the match because:
a.) your field is blank
b.) you know that your first 7 pieces will be unique, and
c.) you can get a head start on stacking before being attacked
d.) it can put you ahead of your opponent, putting you on the offensive
IV. What makes an opener good?a.) the time it takes to execute an opener - the shorter an opener takes, the better, but there are cases when longer openers are better because they pay off better when completed. it is up to you to analyze which openers are best for you.
b.) the reward for completing an opener - an opener is good when you are able to deliver an optimal amount of lines for a certain number of pieces. a tetris opener would be inferior to a t-spin double opener because a tetris opener requires twice as many pieces yet sends the same number of lines as a t-spin double.
c.) flexibility/specificity - openers that can be executed with many different initial bag combinations would be considered to be flexible. you want to go for the openers that are not so specific on piece order (i.e. relying on getting a certain piece early) You should be able to complete an opener 90% of the time. (This is different from me saying you should use the opener 90% of the time, I simply mean your probability of completing it should be 90%)
V. Categories of openersQuick OpenersThe TSD start (
also note that the cousins of the TSD start would be the LSD, JSD, ZSD, and SSD, and they are all rated equally)
Speed: 5/5
Reward: 2/5
Flexibility: 5/5
- This is the opener used to dish out your first 4 lines of garbage as soon as possible.
- It works wonders for punishing openers that take too long such as the combo starts and few b2b tspin setups.
- You want to send 4 early garbage lines to an opponent that you know will not send them back to you right away. This opener also works very well on people who generally misdrop on their first bag.
- Fast players use the opener a lot and are aware that slower opponents will send the garbage back to them, but because fast players downstack better, it is generally not an issue for them. For fast players, however, using a TSD opener is never a wrong answer, but it is certainly not the best answer. Players who are faster than their opponent should go for openers that have better rewards; this will lead to quicker kills as well as putting you on the offensive.
-
Slow players should almost always use quick openers because of their speed disadvantage. It allows you to punish a combo starter or cancel out a quicker opponent's opener for an easy downstack.
- The downfall to this opener is that it does not put you ahead of your opponent because he/she will be able to catch up quickly; leading to an even game (which is like playing without an opener).
The Tetris start
Speed: 4.5/5
Reward: 1/5
Flexibility: 5/5
The Back to back Tetris StartSpeed: 3/5
Reward: 3/5
Flexibility: 5/5
- The generic/default opener used by many
- It is actually practical to open with this on your first match against opponent(s) you don't know. This setup is extremely flexible and gives you two options of either 1. Bailing (by completing the tetris) or 2. Stacking higher
- This opener is good if you want to maintain consistent speed throughout the game (when other openers would make you pause/hesitate)
- Improves your speed in the long run
- The downfall to this opener is that it will never put you on the offensive, and there are always better alternatives to this one.
Medium OpenersBack-to-back Tspin startsThis would include setups such as
Double Triple Cannon,
Super TSD, &
Back to Back T-Spin Triple
Speed: 3/5
Reward: 4/5
Flexibility: 4/5
The Perfect Clear
Speed: 4/5
Reward: 3.5/5
Flexibility: 1.5/5
- Allows you to send around 10 or more lines when completed, filling at least half of the opponent's screen
- These openers have high kill potential when executed properly against:
1. players who are about even with you on speed and stack high(this means that their stack will be high when you are finishing the setup)
2. slow players
3. fast players who misdropped (this will punish them)
- If you are able to complete the setup, you will almost ALWAYS be put on the offensive, unless your spins are spaced far apart time-wise (i.e. there is a 10 second delay in between the first two t spins and a 8 second delay between the 2nd and 3rd spin). With that said, you generally want the attacks to be as close as possible, meaning that holding a T and stacking until you get the second one would be ideal as long as you dont get punished.
- Perfect clear openers also give you a blank field to either prepare yourself for a quick downstack or start a new opener
- The downfall to this opener is that you are prone to getting punished. Some people may feel "committed" to stack upwards until they get the right pieces to finish the opener. This will always lead to them topping out.
- One way to prevent topping out would be to use your t-spins to cancel instead of send lines.
Combo Openers
The Two WideSpeed: 1/5
Reward: 3/5
Flexibility: 5/5
The Three WideSpeed: 1/5
Reward: 4/5
Flexibility: 4/5
The HybridSpeed: 1/5
Reward: 4/5
Flexibility: 5/5
The Four WideSpeed: 1/5
Reward: 5/5
Flexibility: 3/5 for middle, 3.5/5 for side
- Heavy garbage dealers that will certainly raise your opponent's stack
- Will cancel any garbage opponent sends your way when setup is complete, and then send extra garbage to opponent
- Very high killing potential around the 9 combo and up
- Once setup is complete, can only be stopped by another combo setup of equal or better reward
- Two wide is very basic for people starting to get into combos, and it is just as average as a tetris start. when compared to other combo starts, you are essentially taking more time to add more blocks and getting a smaller combo in return.
- Three wide has more killing potential but can be difficult to clear lines consecutively. This is because the amount of blocks remaining after each piece will vary (as opposed to a 4 wide where 3 blocks will always remain)
- The four wide sends a large amount of lines, and a 17 combo 4 wide against a 14 combo will still send 15 lines to your opponent, making this setup extremely potent when completed.
- These setups severely punish any opponent that misdrops on their opening.
- All setups very easy to bail on, and your stacking can actually continue if you bail partially.
- The downfall is that these setups take a long time to setup, and quick openers can easily reduce your combo potential (i.e. if someone sends you 4 lines, that will mean that you miss out on 20 lines you could have sent to your opponent). Another thing is that if opponents use quick openers and continue to send steady garbage at a low stack, they will always be ready to accept whatever you send and send it back to you. These openers are also hard to open with game after game, because opponents quickly adapt to these openers when they realize you are using them. When used in moderation, these openers can definitely put you on the offensive.
VI. How to properly use openersLet me just start off by showing an example of someone improperly using an opener:
You are watching person A's screen who is opening with a 2-wide, while person B uses a TSD opener. As you can see the number of pieces A is able to get before the TSD comes, A is faster than B. The attack from B has only served to complete A's setup even faster. A can then opt to stack further so that B gets his stack up again, and A will then start sending lines and punishing B by sending back the initial TSD garbage.
In order to get the full benefit of openers, you must know the purpose of each opener.
- When using quick openers such as TSD/tetris, you must be able to follow through.
The number one error with many people using the TSD opener is that they take too long to send the next attack after the TSD opener. By doing this, you are essentially giving your opponent 4 lines of garbage to send back to you at a later time, after he's completed his own opener. When opening with a TSD, you must continue sending lines at a steady rate in order to put pressure on your opponent.
- When using medium openers, sometimes you might have to cancel garbage instead of sending garbage in order to complete the setup. Don't get greedy or committed to finishing the opener if there is a high chance you may top out. With that being said, know when and how to bail out of these openers when playing against players who send quick garbage and stack low. An opener is more practical when it has an escape plan to it. By escaping you sacrifice garbage that could've been sent to your opponent for a lower stack to increase your survival rate.
- combo openers need to be used moderately. a good rule of thumb would be to continue abusing a combo opener only if you know your opponent will lose to it every time (i.e. you 4 wide and your opponent loses, and 4 wide again and he loses) alternatively, you can also choose to not use the 4 wide after your first success, so that your opponent won't even know it was a 4 wide, and then save it for later. if you are caught using a combo opener twice in a row or more, this will put your opponent in somewhat of a paranoia as they will try to send you early lines for the next few games.
VII. Interpreting other people's openersNoticing what other people open with is very important because it allows you to adjust your play and exploit the weaknesses of their opener. If they use openers that are executed quickly (i.e. tetris or tsd openers), then it would be a bad idea to use an opener that takes a long time to setup (i.e. 4-wide). You must watch what your opponent is doing so that you can out-do them in opening. When facing an opponent with a medium opening or better, one of your main objectives should be to
force your opponent to bail out of their opener as soon as possible.Opponent speed is also another thing to watch out for. You can categorize people as 1. Very fast, 2. Slightly fast/about even, and 3. Slower. For very fast people, you have to open with a quick opener, no matter what, because all other openers will be punished and bailed openers will be weaker than quick openers. For people in category #2, this is where you will mix up between all 3 openers. mixing things up is good so that your opponents won't know what to open with against your opener. remember to watch what opener they are using! for the slowest people, you should definitely go for the combo openers to end these games quickly. The only way slow people can beat you is if they down-stack a lot of your garbage, so a combo opener would definitely put a lot of pressure on them early game and would work for quick easy kills.
