On a serious note,, you really have to put your mind in the luck of winning and not on your analysis, but what I get is that your analysis and luck works together, most times but on a different basis luck is the altitude when it comes to gamble because with out luck you will have to use all the analysis and you will not win but if in case you win that most be maybe ones or twice.
Am just trying to say that with out luck a gambler will not win up to what he or she is expecting, that's is why a good gambler should just pray for luck and not any kind of predicting strategy
