When trying something new, we often use the phrase "give a go" to express our willingness to attempt something. However, there are several other synonyms that can convey the same meaning. "Try out" and "test out" can be used to express the act of giving something a chance. "Experiment with" implies trying something in a slightly more calculated and scientific manner. "Take a stab at" or "have a crack at" can be used to express a more casual and informal attempt at something. "Give it a shot" and "give it a try" are also commonly used alternatives to "give a go".
