[The following is just me being slightly insane about probability and has no bearing on the point of the artical]
I have to point out some flaws with the probability that you are using here. For the most part betting blue all the time works. However Cards don’t work quite like that. Each draw of the cards reduces the total number of the card that was drawn. For instance if you have 10 cards, 7 blue, 3 red, and after the first 7 draws there have been 6 blue cards drawn, but only one red card drawn then the probability now favors drawing a red card. In fact, if now you switch to calling red for every card you can achieve an 80% success rate over all because now there is only 1 blue card left, but two red cards. Just because you have come up with a strategy for success does not mean that you should stop thinking and reassessing the situation as more information becomes known.
