Bankroll = $10,000
The TC=0 and you bet minimum of $25. You get 9,2 vs. T. The count has dropped to �1. Do you still double down in this situation? I say NO! Just take a hit. If you double you will definitely overbet your bankroll. You have no positive edge at this point in time.
But, let�s stop and take a look what we have here. The count is �1, Right? If the count would have been �1 before you got your two cards would you have bet 2 units? Obviously NOT. So, why would you double your bet now when you don�t have the best of it?
Now, let�s say the TC=+2 which gives you 0.5% edge over the house. You next bet is Bank*0.5% = $50. You get 9,2 vs. T. The count now is at +1 and you don�t have any edge at this point. The game is even. Would you still double? I say NO! If you double your bet the only thing what you will accomplish is increasing the VARIANCE for no monetary gain whatsoever. Just take a hit. Now, if the dealer�s Upcard would have been any card under 9 you would double down because you would have in action exactly Bank*Edge. Also, you would have double down if your 11 would have been 5,6 or 7,4 and probably 8,3.
Now, let�s say the TC=-3 and you bet $25. You get 8,8 vs. T. The count is �4. So, you will Split for another $25. You get on your first 8 a 3 for a total of 11. The count is �3. Would you double down? I say No! But if you do you will have 3 bets on negative count. But, hey! ..do whatever you want! Ok, let�s say you do double. Now let�s go to the next hand and you get �lucky� again and get another 3 for a total of 11 and the count is at �2 now. Do you double down on your second hand? Let�s say you do.
You have now $100 riding on a TC=-2. You have in action 1% of your bank when you�ve got �1.5% against you. You don�t have the best of it. Why would you do that?
