Hold'em Blackjack

[pokerking2006]

i played this over the weekend and had loads of fun, its quick and i learnt the game in about 10 minutes (and somehow started winning), i have read the above posts and was just wondering about other peoples startegies, mine is pretty basic at the moment, fold the first card if it isnt a ten and fold if someone else is showing an ace. Also, which crypto sites are people using for this.
