Being an International player I can say that there is some flaws in Adda52. First the card delivery is pathetic as the quality of hand clearly shows the card delivery does not go through "Burning" process.
Sometimes there software favors the losers. For example in a game my Four of a kind was killed by higher four of a kind which happened in the "River". This has happened two times to me in a day.
Sometimes there are one players playing with two ids in a room, making you to be killed.
For example in a high BB game after few hands it was obvious that there are multi ids. So after few hands folding when I placed all in suddenly the players folded as they know what is going to happen.
The main problem is lack of liquidity and non placement of players automatically after few hands I.e. a player must be shifted in another room of same BB automatically after few hands. This is the fair practice run by several renowned sites like 888poker etc.
Now here is my golden words for you.
Never play in less than 6 persons a table.
Always play the hands 7and10 and 8andJack at adda52 boldly. As these are the higher won percentage at adda52.
After winning a good amount say 10000 in a day. Just go for two days holiday I.e. keep away from play.
Try to avoid higher stake games in night as that time the chances of Leak and fraud are high.
Do not sit at extreme left and extreme right in a room.
Always withdraw your 75% winnings.
First time I made 800 from 100 in an hour but lost in one hand.
After two days I made 8200 from 3000 but lost all by two hands of higher Four kind.
Then after studying the game patterns and mostly the card dealing behavior I am making good amount.
For example I made 23000 from 3500 yesterday.
Good luck
