Common Timing Attacks

1 Base can support a 1/1/1 build comfortably, allowing opportunity to expand. Needs 1 gas.

To contain the opponent, allowing attacker to expand freely. Try to siege tanks so that ramp is in range to stifle attempts at reinforcement. If opponent has walled off, siege in tanks of his buildings to be able to snipe of depots and addons.

Great for setting up a contain on your opponent - Strong on maps with narrow paths or cliffs

Immobile.

Expect to see 1 gas early and 2nd gas after factory. Is based off 1/1/1 build.

Once a contain has been set up, the attacker is free to expand and take complete map control.
Users can continue to rally to the front, adding Vikings to gain tank range, and also buildings turrets to limit the range of defenders Vikings.
This opening transitions well into Marine/Tank/Viking

1 base mining no gas is enough to support constant marine production on 5-6 rax. It’s also possible to mine 125 gas to build a tech lab and research stim to make the marines SUPER EFFECTIVE

To flat out kill the opponent, or at least do enough damage to heavily cripple them moving into the mid game. If you want to 100% all in, bring scv’s to act as fodder for enemy marines.

Very mobile force. If opponent is caught off guard it can be very dangerous.

Very all in. If defended well opponent has almost certainly won through having higher tech and or being able to expand first.

Can be hard to scout if the attacker has walled off. If you can get inside base, expect to see no refineries. Players walling off at the bottom of the ramp is another big sign.

4 rax marine still leaves room to expand, whereas 5-6 rax is very all in and is aimed at killing the opponent immediately. If doing a high econ mass marine, once you expand, throw up 4 refineries and tech to your chosen composition.

Allows room to expand off initial timing attack. Helions are a great mineral sink.

To kill as many workers as possibly to cripple opponent moving into mid game, allowing you to take economic lead.

Very mobile. Helions are the best unit in the game to kill workers on a mass scale, after banelings. Also great against marines. If pulled off well gives you a great economic advantage.

Leaves front weak to other time attacks such as tank marine, or banshee harass.

1 gas early and 2nd gas after factory. If you see a tech lab on the factory and past 6:00 and no tanks, chances are it’s blue flame hellion.

Can lead into expo. Fact can be swapped with starport to get out banshees to do further harass. Can also transition easily into marine tank viking as you have the base production sturctures ready.

The idea is to fast expand whilst putting on pressure. Take no gas at the start. After your first 2 rax build a 2nd cc. You can then add a 3rd rax and constantly produce marines and workers. When once you can afford it throw down 1 gas, followed by a factory and tech up to tanks and medivaces.

To delay and punish zerg fast expand, whilst expanding yourself. Also forces zerg to make lings instead of drones, giving you an economic advantage. Allows for a stronger mid game push. Ideal targets are queens and overlords. If you can snipe the natural expansion that is a bonus.

You can either hit with 3 marines to try and catch your opponent off gaurd, or wait for 5-7 marines, though waiting this long can make the rush much less effective unless the zerg is droning super hard.
Only do this build if you see the zerg fast expanding. If they haven't expanded by 4:30 they will be teching and you should abort the rush and build a bunker or 2 at your front.
The attack is more effective, the closer you build your bunker to the hatchery, so building it before the hatchery is finished is ideal as the creep spread will block your bunker from being put down within range of the hatchery very quickly. Not only will building it closer allow you to shoot the hatchery directly from the bunker, it also decreases the area that zerg has to build a spine crawler allowing you to possibly snipe it from inside the bunker. This being said you'll also want to build the bunker just outside of the vision range of the hatchery, or any overlords or the zerg will pull drones to delay or even force a cancel on the bunker. You will want to keep your scouting worker alive for as long as possible, not only to build the bunker but to repair it as it is being attacked.

Scouting it early is essential. Keep an overlord just in front of the hatchery to scout for any lingering scv's or bunkers being put down.
If you do scout it early, pull 5-6 drones and try to focus down the scv building. If a marine shows up by itself it's also possible to surround and kill it for minimal losses. If you hadn't scouted it, build a spine crawler and uses you queens transfuse efficiently to pick it off from a distance. The spine crawler has a longer range than the bunker so this is the most effective way to destory a bunker. Keep zerglings nearby and try to get a surround on any marines that get greedy and leave the bunker. It's a bad idea to attack the bunkers heard on after they are full as 4 marines and a repairing scv is more than enough to fend off 10's of lings.
It can also be a good idea to send a few lings to the middle of the map to cut off any reinforcements, and also flank any retreating marines once the attack is finished.

Highly cost effecient. Very hard to stop if not scouted early. Allows for safe expansion at home. No gas required.

Can be costly if picked off early. Requires good multi-tasking.

Using a drone scout, 2 rax wall off is a big sign of early bunker play. Place overlords around FE to scout for bunkers being built. Take Xel'Naga with scouting worker to see rallied marines.

Fast expanding and tech to Marine/Tank/Medivac as the standard TvZ gameplan. Can also transition well into Marine/Thor as you already have the 3 rax.

A player who plays this build will be able to support it off 1 base with 2 gas, but if they try to expand behind it, will not be able to fully reinforce the attack.

To do maximum damage to either win outright, or cripple the opponent enough to expand and take the win later.

You'll want to get an observer spying on the Terran tech path and find the optimal time to attack. If no bunkers have been constructed force your way up the ramp, leading with zealots. Use your observer to get sight of the high ground and snipe important units, structres with your stalkers and immortal. If the opponent fast expanded, use your sentries to block the ramp to suffocate reinforcements.

Scouting early is important.You'll need 2 bunkers ideally at the front of your base, and hotkey 5-6 workers to be ready to repair bunkers. Snipe the Immortal and then clean up the rest, Stim and Concussive Shell are super important to defend this push.

Very stong push, does maximum damage. Getting quick observer will help to defend cloaked banshee rushes.

Very economically draining. Immortals can't warp straight to opponents base so losing them is costly.

Protoss' 2nd gas will go down after their 2nd gate, and you should be able to keep your SCV alive long enough to scout the robotics facility being planted. Try to keep it there long enough to see it finish to make sure they don't switch tech path, though this is rare.
