My first reation was to raise this river with BB holding a weak Ace that he can't seam to let go because SB would have to be a terrible player to play KK/66/22 this way.

However, after studing the hand for another minute I realize this might be a very well played 66/22 by SB. If SB C/R the turn he he likely to only collect 2 more bets from Hero while pushing BB off his weak Ace. So by calling the turn and donking the river he makes 3 bets minimum or 6 bets if Hero is aggressive enough to raise which I think many players might as a good value raise with BB in there.

Even if BB is a total calling station and calls two cold on the turn then villian only collects 5 bets maximum. So it's 2(min)/5(max) with a C/R turn line for SB or 3(min)/6(max) with a smooth call turn, bet/3-bet river line.

So I think Nick is correct in just calling the river donk.

I would like to know if other 2er's agree with me that if SB has 66/22 he played it optimally.
