A default tactic is a general strategy that a team uses at the beginning of a round to take control of the map and set up positions for executing specific strategies. Here are some steps to create a default tactic in CSGO:

• Determine your team's strengths and weaknesses

 Your team's strengths and weaknesses will influence your default tactic. If your team is good at taking early map control, then you may want to focus on taking positions that give you the advantage. If your team is better at reacting to the enemy's play, then you may want to focus on more passive positions.

• Create an initial map control plan 

Before you execute any specific strategy, you need to establish map control at the beginning of the round. This means taking control of key areas of the map. Decide on you will split your team and which players will take which positions to take map control.

• Identify potential threats and counters

Once you have established map control, you need to identify potential threats and create counters. This means anticipating where the enemy may push and creating a plan to counter their strategy. Identify common hiding spots and possible rotations that the enemy may use.

• Set up crossfires and support positions 

Crossfires and support positions are essential for holding down areas of the map and creating a favorable engagement. Make sure that your players are in positions to support each other and are not isolated.

• Practice and refine 

Once you have created your default tactic, you need to practice and refine it. Play scrims, watch demos, and analyze your gameplay to see what works and what doesn't. Make adjustments to your tactic to suit your playstyle and strengths.

Creating a default tactic is essential for any CSGO team. It can help you take control of the map and set up positions for executing specific strategies. By following the above steps, you can create a reliable default tactic and improve your chances of winning rounds. Remember to practice consistently and make adjustments as needed to stay ahead of the competition.
