As great modern thinkers say, the second swing is worse than missing. If you decided to defend, don't let go, never fake. Once you've made a decision, there's a 50/50 chance that your opponent will fall for it or think that you're just faking again. Either you take the risk and win the round, or your opponent takes the risk, but based on match statistics that are not confirmed by anything other than the author's observations, 80% of CT players fake, which T-side is used to, and rarely checks if the CT player is faking in the first few seconds of defense, thus, if you don't fake, your chances of winning the round are significantly higher. Never fake. This case is made in support of the NEVERFAKE movement, so if you decide to open cases, go for it, as great modern thinkers say, if you're going to do it, do it like a king. If you decided to open cases, keep opening until you have a full inventory or empty pockets.
