AIMING
This is a key thing in this game. If you have got good and stabile internet, this will be your advantage against others and you will be able to enjoy the game more… But if your connection is not that perfect - than it will be your limitation, scoring will be more difficult for you.
How to minimize your limitation and let increase your chances?
1) In many cases is better first shoot and then aim. Simply don´t waste your time by aiming and then shooting.
2) Move your hand faster (you don´t need necessarily to change your mouse sensitivity, just move your hand faster).
3) Keep your hand relaxed, don´t be in a tension. Tension frozes your hand. Tension comes when we "really need to win!".
4) Most people are jumping over the lines. Do your lines rather above than bellow. But also be prepared for your enemy´s crouch.
5) Don´t line too much. Enemy can hear you and then it´s for him much easier to estimate where you probably are. "Be invisible"
6) You can try some easy hand script. For example, this one is mine:
bind "MOUSE1" "+attack"
bind "MOUSE2" "+changer"
bind "MOUSE3" "hand 2"
alias +changer "hand 1"
alias -changer "hand 3"
MOVEMENT
1) When enemy shoots at you at a large distance - don´t move too fast from right to left and from left to right, because there is certain delay in your enemy´s balls which he fired into your direction and it may happen that you would jump into his line.
2) When you encounter enemy, don´t jump immideatelly back to the position from where you came and where the enemy first saw you - you could easilly jump into his shot.
3) Don´t stay at one place too long, change your positions. Don´t do all the time the same things. Be present. For your enemy will be much more difficult to determine where you are and where you will be.
4) Watch your back for campers.
5) Remember that you have a time, you don´t have to rush at all cost, play with your enemy :-)
You can also try visualisation or imagination. Simply imagine that you are going to score this round. (Every our image, thought or conviction is being written into our subconscious mind and subconscious mind then automatically controls our external behavior and action).
Last tip: Do not want to be better than someone else
