Not to say that your strategy isnt right for you but I think there might be a couple of problems in it. Like one where you said that you dont want to raise preflop with a good hand in order not to give your hand strenghth away, well what if you have
. You probaly dont want to limp in most of the time because that will cause other people to limp in with you and when you have to go agaist alot of opponets with Aces you odds of winning will go down. So I would usally raise with big pocket pairs preflop about 90% of the time.
Another thing is that you dont want to make your bets according to the size of the blinds after the flop. Pre flop this is fine but after you probaly should be looking at the size of the pot when you are decideing how much to bet.
