On my last trip to Vegas (downtown) I played 80% DDB at the $ level for about 3 and half days. I came home a winner with an extra $800. I have been using the VP Pocket app, on my Android tablet as my training aid. According to the app, I am playing with 98-100% accuracy. Is this app providing sound and accurate strategy? Is $800 profit a respectable outcome for 3+ days of "work"? Also, there are a couple of hands that come up I have difficulty with. One of them is 4 high cards (i.e Tc Qh Kh Ad 3h) sometimes the app says you should hold all the high cards and go for the straight, other times it will just have you hold the suited pair. What is the rule? I can't seem to figure out why one hand is played differently from the other. Does it really matter or am I just spitting hairs. If VP Pocket is not the best trainer, what app should a buy? I have a copy of Wolf Video Poker, but there are a lot of settings in that program that I do not understand.
