Do pick up guns of dead people to top up your own ammo, but make sure you reload first. Very important on wall spam maps like de_nuke.
Do not waste your HE Grenades unless you know the enemy is there. They are very valuable and can do a lot of damage to the opposition if they placed in the correct location. Far too often people throw HE Grenades with only the hope that the opposition might be there, or attempt to use them to stop a rush.
Some players are really good at avoiding Flashbangs. Use a Smoke Grenade to force them to avoid the Flashbang effect, then throw the Flashbang in. If you time it right, the Flashbang will be exploding in the persons face right about the time they have spun back from trying avoid your fake Flashbang (Smoke Grenade).
Concentration required to play well for an entire map, is NOT something that the individual or team will acquire over night. This is a learned skill that takes practice, and can only be acquired by playing several matches in a row, 1 after the other. 3 maps quickly in a row, that is, no real break in between each map/match, of actually trying hard to play properly and win against opponents that test you, not just a team that you can walk over in your sleep, is the only real way to achieve this. That is why it helps to play teams that are as good as you or better than you when you are practicing. Good Teams playing against very bad opposition for practice, tends to make that good team sloppy, and they lose their hardened edge.
Get a plan and stick to it. Practice the damn plan, and test it to exhaustion in practice wars to see if it actually works and has the outcome you expect. Have alternate plans if it is obvious that your original plan is never going to work. Like finding out 1 site has 3 AWP's in it and you have no smoke grenades.
Pay attention to the what the opposition team is doing each round and act accordingly. If they are 5 man rushing the same spot all the time, have 1 player spot for you and then give them the HE Grenade welcoming mat. If they have the same defensive position every round, learn to pick them off, or work out how to put them out of position, or even better, bypass them altogether.
Don't all throw your flashbangs at the same time or in the exact same spot. Spread them out a little in time and placement. If you all throw 1 flashbang at eactly the same spot at the exact same time, you only get the equivalent effect of 1 flashbang. If you throw them 1 after the other with slightly different placements, then your are more likely to ensure you have flashed the opposition player(s) you were trying to flash, and kept them flashed.
Do not replenish your armour at the start of each round. 50% armour is just as effective as 100% armour. Only re-buy your armour if you get down below 30% (because at this level or lower, you may actually run out of armour before you die) or you weren't able to afford full armour with a helmet (something I believe is a failure in the game, as you should be able to buy a helmet separately, without having to buy a new vest as well).
When communicating enemy positions, be precise, and give numbers of players, and weapons when possible.
Call your status out, eg. "Reload", "Throwing Grenade", "Throwing Flash", "Throwing Smoke", "Blind", "I have X Health" etc.
Unless rushing in a group, good players when they come around a corner only reveal the absolute minimum of themselves for the shortest time possible, to pick off the next likely camping position. Map knowledge is crucial in this regard and a skill that requires constant practice.
Don't run behind each other, fan out in as widespread a pattern as possible, so you can't get owned by a single player. You may want to disobey this deliberately if you have a specific flash rush strat, but I think it will be rare.
Do make a lot of noise if it is your intention to act as a decoy or create a diversion.
Don't break Windows and Vents when you are close to them, or you need them intact to alert you to possible enemy movement.
Don't stand still to take on a camped enemy. You will just get spammed to death along with the rest of you team. The entrance to site B on dust2 from the tunnels is a classic example of why you don't stop to take the guys camped outside B double doors. You will die and cause the rest of your team to die as the get stuck behind your lifeless body.
Don't rambo, at least not against good teams/players. If your teammate(s) are 10 meters behind you, they are not really going to be able to give you very good support? If they have just shot a whole clip of ammo, they are going to be reloading right? Why weren't you out there shooting at the opposition as well in the first place? If they have bought grenades, they are going to want to use them at appropriate locations, right? You running out like a headless chicken is not going to help one bit, and ruins the perfectly good flash they were going to throw, because you are now in the way, AND they have to also switch back to a real gun!
Do shoot close and far corners of walls, doors and boxes as you move around the map, to push opposition players out of position. Practiced enough, you can even get kills this way.
Do spam walls and boxes of likely camping positions of enemy players as you move around the map.
When spamming, do not have the whole team doing it at once, learn to alternate between yourselves and only empty half a clip at a time, then reload. This ensures that somebody has a gun out with ammo, and you can cancel your reload sequence if the opposition comes, and not be entirely defenceless. Terrorist Notes
Do not buy Glock Ammo EVER!!.
Don't run to the bomb site with the bomb in your hands and your back to the likely spots the Counter-Terrorists will appear from or where they maybe camped. Bombsite B on de_cbble is a good example of where this happens a lot.
Use Flashbangs & Smoke to COVER and buy your bomb planter time to get the bomb down. Plant the bomb as wide out in the open as possible. Or previously specified points as per map tactics.
CT-
Don't defend the bombsites as Counter-Terrorists exactly the same way, every round. You need some variety to your defence, or the Terrorists will wise up (if they even remotely clever) and you will get picked off with grenades, or shot through a wall.
If you are a Counter-Terrorist and the bomb is dropped, inform your team immediately. If the bomb is dropped in your favour, everybody on the Counter-Terrorist side needs to converge on that area via the safest possible path as quickly as possible and camp the bomb from the best positions available in that area.
Don't die to 4-5 man Terrorist rushes, unless you have a really good spot, it's better to fall back and have 5 Counter-Terrorists to take back the bombsite than to die needlessly.
If its 2 v 5, and bomb in planted don't try to defuse, unless it is the last round of the half or sudden death and you have nothing to lose, meet up and camp a position outside bomb site to pick off as many Terrorists as possible.
Announce the fact to your team that you have a defuse kit.
Crouch when defusing, you are a smaller target.
Turning away from FlashBangs doesn't do anything to avoid the FlashBang effect !!!!!!!!!
