I don't know if shiv is the strongest but he is definitely more strategic than anyone else. But I have a feeling that his strategies are gonna be his biggest weakness. He is a pakka BB material ; knows the turns well but he forgot that even if the game is same, the players ' moves are always different & unpredictable.
If staying with P-A-A was a part of his game plan he should have stay put there for few weeks but him joining the circus of those nasty clowns made him look more like an opportunists less of a player.
Abdu is smart, but I don't know why he's changing gear as well. If it is about choosing the majority, then BOY! Are they helping Pri? Cornering her is going to only make her stronger & she is already a capable lady.
For now, Ankit, Archana, Gautam (still a ping pong ball though) Abdu - coz of his teply to Tina looks good.
Rest are much nonsense, so I won't waste my breath on them.
