Firstly, i do not agree that "strategic methods" are needed in a simple game of Pool, although i would agree if this was the case in Snooker. Snooker is a more sophisticated game compared to Pool, this requires good thinking and skill where as playing a game of Pool where for example, you have a rating of 500 and you play a begginner, would only have half chance of winning because you could pot eight ball anytime (refers back to luck).
This has nothing to do with the topic, i just realized lol but adding those rules to Pool would change dramatically, i think this would put off some of the regular 8 ball players because imagine if you have two balls left both on the rail with no chance of potting, the opponent is on 8ball, wouldn't your first instinct be to "hide" the ball?
Leave 8ball as it is, if anybody likes to hide balls and play strategically, then i suggest playing snooker as it requires a good mind aswell as good potting abilities :p
