Hello I'm sure this is something you all noticed but many times (I haven't done an exact count) if you isolate doubles e.g. Texas the single digit from the previous drawing forms the double component of the next doubles win. So say the current doubles winner was 121. You just play 220, 221, 223, all nine numbers and I'm sure theirs a simple way of reducing this set further. If you can reduce the number set further scale up your bets and play until the next double hits, win or lose, and then start over. Let me know if I'm off base here.
