I think:

Lisa and Robin- Rumba- 7+7+7+7= 28
Michael and Natalie- Argentine Tango- 7+8+8+8= 31
Louis and Flavia- Paso Doble 7+9+10+9= 35
Denise and James- American Smooth- 9+9+10+10= 38
Kimberley and Pasha- Tango- 9+9+9+9= 36
Dani and Vincent- Samba- 8+8+7+8= 31
Victoria and Brendan- Salsa- 5+5+7+5= 22
Nicky and Karen- Charleston- 8+9+9+8= 34

B2- Lisa and Michael

Leaving: Michael

Lisa and Robin - Rumba - 7+8+8+8 = 31/40
Michael and Natalie - Argentine Tango - 7+8+8+7 = 30/40
Louis and Flavia - Paso Doble - 8+9+9+9 = 35/40
Denise and James - American Smooth - 10+10+9+10 = 39/40
Kimberley and Pasha Tango - 8+9+9+9 = 35/40
Dani and Vincent - Samba - 9+9+9+9 = 36/40
Victoria and Brendan - Salsa - 5+7+7+7 = 26/40
Nicky and Karen - Charleston - 7+8+8+8 = 31/40

Bottom two - Kimberley and Victoria
Eliminated - Victoria

I'm not going as far as to predict scores, but I think this week will be when we start to see the least popular of the 'favourites' in the bottom two, probably against one of the lower tier. I think that will either be Kimberley, as she's been there once before, or Denise simply because it feels inevitable to me.

As for the lower-tier - I do not think Nicky will have a bounce in him, as we're at the serious stage of the competition, the time for sympathy votes is over, and he's simply not as good as some of the others - even if he does score well with the charleston he is likely to be nearer the bottom of the leaderboard anyway. If Victoria ends up at the bottom of the leaderboard again, the public may not choose to save her from last place for a second week running, though.

So I'd be surprised if the dance-off wasn't Nicky vs any of those three.

Here are my predictions.

Lisa and Robin - Rumba - 6/7/7/7 = 27
Michael and Natalie - 6/7/8/7 = 28
Louis and Flavia - 7/8/8/8 = 31
Denise and James - 9/9/10/10 = 38
Kimberley and Pasha - 8/8/8/9 = 33
Dani and Vincent - 9/9/9/10 = 37
Victoria and Brendan - 6/6/7/6 = 25
Nicky and Karen - 7/7/7/7 = 28

Bottom 2: Lisa and Robin v Nicky and Karen
Eliminated: Nicky and Karen after 2-2 judges split with Len saving Lisa.

Denise & James - American Smooth - 9, 10, 10, 10 - 39/40
Kimberley & Pasha - Tango - 8, 9, 8, 9 - 34/40
Louis & Flavia - Paso Doble - 8,9,9,8 - 34/40
Lisa & Robin - Rumba - 7, 8, 8, 8 - 31/40
Dani & Vincent - Samba - 8, 8, 7, 8 - 31/40
Nicky & Karen - Charleston - 7,8,9,8 = 32/40
Michael & Natalie - Argentine Tango - 6,7,8,7 - 28/40
Victoria & Brendan - Salsa - 5, 6, 7, 6 = 24/40

Bottom 2: Victoria/Brendan vs. Michael/Natalie
Eliminated: Victoria/Brendan

Would very happily be wrong.

Lisa and Robin- Rumba - 7,8,8,8 = 31/40
Michael and Natalie- Argentine Tango - 8,9,9,8 = 34/40

Denise and James- American Smooth - 10,10,7,10 = 37/40
Kimberley and Pasha- Tango - 9,9,9,9 = 36/40
Dani and Vincent- Samba - 8,8,8,9 = 33/40
Victoria and Brendan- Salsa - 6,7,7,7 = 27/40
Nicky and Karen- Charleston- 6,7,7,7 = 27/40

Bottom two: Louis/Nicky

Denise and James- American Smooth- 9, 10, 10, 10= 39/40
Kimberley and Pasha- Tango- 9, 8, 9, 9= 35/40
Dani and Vincent- Samba- 8, 7, 8, 9= 32/40
Victoria and Brendan- Salsa- 5, 6, 7, 6= 24/40
Nicky and Karen- Charleston- 6, 8, 8, 7= 29/40

Lisa & Robin - Rumba 8,7,8,7 = 30/40

Bottom Two: Nicky and Michael

This is becoming my weekly 'guilty pleasure'. So far, I'm pretty certain I have much less than 50% of individual scores correct and hardly any overall scores correct. Oh, add to that, I've not even been close to getting the order correct!!

Lisa & Robin - Rumba 7,7,8,8 = 30
Michael & Natalie - American Smooth 9, 9, 9, 9 = 36 (bet I have a purist AT fit at this one!)
Louis & Flavia Paso Doble 8,8,9,9 = 34
Denise and James 9,10,10,10 = 39/40
Kimberley & Pasha 9,9,8,9 = 35
Dani & Vincent 9,9, 10, 9 = 37
Victoria & Brendan 6,6,7,7 = 26
Nicky & Karen 7, 8, 8, 8 = 31

Still think it will be Lisa and either Nicky or Kimberley.
Obviously, Louis would be in danger but, unless he's up against a front-runner, I think he would get through the dance-off.

If Louis is low/middle of the pack, I will definitely be re-assessing whether he could win or even if he'll make the final - he could be the Strictly Shocker rather than the long expected Denise! But I think he'll be safe this week.

Bottom Two: Lisa and Nicky
Eliminated: Lisa

Denise - 38 (9 9 10 10)
Dani - 35 (9 9 9 8)
Kimberley - 35 (8 8 10 9)
Louis - 35 (8 9 9 9)
Nicky - 31 (7 8 8 8)
Lisa - 28 (7 7 7 7)
Michael - 27 (6 7 7 7)
Victoria - 27 (6 7 7 7)

Kimberley and Nicky in the dance-off.
Nicky eliminated.

Nicky will go but I hope it is Lisa - she can only do a big cheesey grin and wave herself around.......not very edifying :<

Denise 38
Dani 37
Louis 35
Kimberley 35
Nicky 31
Michael 31
Lisa 29
Victoria 27

Dance off 2 from Nicky, Lisa, Victoria and Kimberley based on my take of public voting.
At a push i would say between Nicky and Kimberley as the public will vote to keep Victoria and Lisa in

Denise - 9 10 10 10 - 39
Kimberly 10 9 9 10 - 38
Dani - 9 9 9 9 - 36 (can't see anyone getting a 10 for a samba before the final)
Nicky - 8 8 9 8 - 33 (think they mark higher the week after they save someone.)
Lisa - 8 8 9 8 - 33 (think people are underestimating this. Anything that's not a disaster will be taken as a success, brave change, shows she can do slow, etc. The judges love her.)
Louis - 7 9 8 9 - 32 (I hope higher but I think Len will think it's not traditional enough for paso because of the music and Craig giving Louis a 7 is now seen as a good score)
Michael - 7 8 9 9 - 32
Victoria - 6 7 8 8 - 29

B2 - honestly no idea.
