Here is a tip to help you make the right decision.
Everytime I make an action I do it and then move the mouse button to the other side of the screen and take my hand off the mouse.
This does two things.
1) means that you do not make impulse clicks of the button ( because the mouse is not over the icon to call and your finger is not over the mouse button )
…..I used to find that most of my leaks for impulse calls without serious thoughts to teh way the hand or opponent had played.
2) it provides time for you to consider what to do next and removes the pressure to action immediately.
