I hope you have found this site okay. There is alot of information here. You are a pretty good player, but you have to take it to the next level. You already know basic strategy pretty well, but you mist know it perfectly. Here is a link to Ken Smith site to get you going on mastering basic strategy. I look at it myself before a trip to refresh my brain.
The next step would be to buy "Professional Blackjack" by Stanford Wong. It can be bought through this site or ordered from ant bookstore.
Please don't mention the casino we were playing at or use any real names. Everyone uses a "handle" name here. Make up a name if you want to post.
PS. To any your question. No, I don't always win, but lately it sure seems like I do.
