Standard Shove Scenerios

[JanelleBB7]

So I hear this a lot from the 2+2 posters: "Standard". But the problem is I don't know what situations are all standard. I hope I don't get flamed for this idea, but I would like to know if we could develop a list of standard shove scenerios (on the turn or flop). This could really help me in my game. I would like to have a clear list in my head of plays that are just plain standard. It may be the ABC's to you guys but I am not sure how you all always know what is standard.
