What mistakes cost you games when you were Bronze/Silver
So I'm not 100% sure what it is you're looking for, but I did once write about great ways to learn Starcraft, and I've given advice to people who feel that they're stuck, and I've even posted on dealing with common build orders. But I'm going to assume you've seen all that, and its not what you're looking for.
I could lecture you on the fundamentals (like Opera did) and why watching high level games is a waste for a new player, but you didn't seem receptive to that, so I'm going to treat you like how I treat my friends who are learning Starcraft 2, and I'm going to explain exactly what you need to do to win.
Usually I like to start new people with Protoss because I feel like they're the easiest race to learn; and the build I like to describe is called the 4 Gate. With solid execution you can get to Diamond with just about any build (this is where fundamentals trump strategy), but the 4 Gate is a really easy build to execute, so that often helps people who are new to the game.
The most important thing about any Starcraft 2 build is constantly building workers, so for the moment, unless I say otherwise, assume I'm always telling you to build Probes. In fact, the number I'll stick next to most of these things is about the number of Probes you should have at that point. Additionally, most of your Chrono Boost should be on boosting Probes.
The 4 Gate is a "Core First" build which means (despite its name) you're going to build 1 Gateway then a Cybernetics Core. Because you don't want to build the Gateway before you have your economy, this usually means Pylon on 9 and Gateway on 13. You can play with these numbers, but the key here is good execution so inevitably you're going to find those numbers some of the best.
From here you'll want Assimilator (14), another Pylon (16) and the Cybernetics Core (17). Usually players like to get an early Zealot (18) out of their Gateway to stop any funny business, and then back that up with an early Stalker (22).
They key to a 4 Gate is your Warpgate technology, so as soon as that Cybernetics Core finishes (around 20 Probes or 24 supply). You'll want to save a Chrono Boost to make it finish faster. From here you'll want to drop the other three Gateways (for a total of four, as in 4 Gate!), and another Pylon.
Around 26 Probes you should stop Probe production (this is called cutting your workers) and just warp in Zealots and Stalkers. This should be at about 5:30 into your game and, at this time, you'll want to start pushing out. Make sure to bring a Probe to build a Pylon near your opponent's base (this is called a Proxy Pylon) so you can warp in reinforcements. As soon as it finishes, Warp in another bunch of Zealot/Stalkers, and attack.
This Attack should be at about 6:00 minutes into the game.
More than likely your first attack will not come at the 6 minute mark, but at the 7:30-8, and this is sort of the difference between a Silver/Bronze player and a Diamond player, those 2 minutes; because if you can launch an attack two minutes earlier, its likely he'll have half the army and won't be able to handle you. So you're goal then becomes: getting that attack down to the 6 minute mark.
This is called: working on your Execution.
You get that down and you can stomp your way through to Diamond.
After thinking about this a bit, I interpret your question as follows:
Which tactics can I execute today that will cause the most distress for the opponent for the least distress of my own, and can be executed in ALL leagues of play?
If you are a superior player to the bronze you wish to beat, then do as everyone else has said and just out play them and forget about this.
If you are on equal footing, then practice and you will eventually beat them.
For today, you will have to find a way to cause them distress in the most cost-effective way. And by "cost" I include both your mental focus as well as minerals / gas (for example multitasking will cause your own game to suffer because you will forget to macro).
For example Kiwikaki's blink stalker + mothership recall is probably not viable because it requires so many things to be in place and tons of APM.
Because the goal is "little effort for me", you should be careful to choose tactics that you can carry with you as you get better, or could help develop your gameplay instead of just going for a cheap win that will over-promote you to gold. This is why I said "ALL leagues of play".
For example I would exclude things like the planetary fortress rush. Maybe that could win a large number of games, but it would be completely invalidated past silver league I think.
Here are some other ideas:
- As Protoss, at the very start, build a pylon in their base they can just barely see, and that's far from their mineral line. Bronze players may send their entire worker line out to kill it, and you can easily cancel it before it dies. This is completely worthless if you're playing anyone that knows better.
- Send a few cheap units periodically into an unguarded base of theirs. Manage the attack if you can, but favor just letting it go by itself. Obviously there are a million things to consider to make this more effective. But just a few keystrokes here and a couple hundred minerals could take down an entire expo, force their entire army to relocate, force them to retreat prematurely if you're mid-battle, force them to spend 2000 minerals on static defenses, and more to the point: their fundamentals will suffer because it takes them much more effort to defend than it took you to attack. This is a good way I think to warm up to the idea of multitasking in general, to get used to the idea of "my army is fighting and I'm not watching it". So this tactic can be evolved and developed over time as you get better.
- Hallucination is something that, on the battlefield, will often not go detected, and bronze won't have the game sense to even realize it's hallucinated. A couple keystrokes and your army looks twice as big and will absorb so much damage. The opponent may just 'gg' naively at the sight. It has huge potential at higher levels too, which makes this also a valid tactic.
Hmm I can't think of any more. But hopefully I have made the question more specific so others can contribute?
When you are in bronze/silver/gold league you have to concentrate on one thing only : fundamental mechanics.
It may sound silly but most of low level players focus on things of much higher level concepts such as microing units, timings or gaining map control.
There are three main things you need to focus on :
- First you should focus on is your macro. Try to find a standard build order for your race and focus on spending your ressources. If you manage to keep your ressources low (minerals < 500 and gas < 300) by spending it on buildings / units. You should produce workers (SCV, drone or probe) continuously at until around 100 supplies.
- The second thing is to know what you are doing and what your opponent is doing. Don't play blind games. Try to scout regularly your opponents (every 2-3 minutes is fine) in order to know what he is doing (tech, army size) to be able to react to his moves.
- The third and last thing you should focus on is to use your units. Control Xel Naga towers, scout or harass your opponent, make a push for the win. There are many things you can do with your units, but they should NEVER be idle (unless you are massing them before attacking).
Of course, it may take some time to master these aspects of the game but if you train as much as you can, you will be a gold level player in no time. When these are natural to you, you will be able to focus on the other aspects of the game.
EDIT
You don't need specific tactics to beat a bad player. You just need to have better fundamentals. If you want a "magic" build order to win 95% of your games, it doesn't exist.
