Everybody is saying Vanessa is playing a great game, and she has been so far, but at this point of the game if she doesn't make a big move and split the Austwins she is sealing her fate tbh. She's playing the game for 3 people that will never (unless Liz is evicted) turn on each other, basically playing for 4th place right now.
Her best chance of winning IMO is to take out Liz, make a solid final 3 with Meg & James, and if they are F3 she has to win HOH over James (cause no way Meg is winning a 3-part HOH), vote him out and win against Meg in F2. Make it happen, Vanessa!
