re: Poker & Practicing HUSnG with play money sites
First, you can have as many accounts as you want on PokerStars
. I personally have 3, not all of them are mine, just one, but I've registered with 3 accounts that play regularly on PS. You are allowed to receive just one bonus for one household, but you can have as many accounts as you want providing they have different but real account details.
Other than that - every poker room should have play money heads up, if you have an Android device you can search the market just aswell, I bet you will find something.
When I first joined PS (PokerSchool) there was a test with all the different situations asking you what would you do if .. If you can find such test for HU it would be probably better than an actual experience
