PLO hand with deep stacks, sidepot.

[Ojingo]

$50 PLO, 6-max. Normally, I don't play very differently on 6-max compared to full ring, but this time my opponents seemed rather predictable, so I've been playing very LAG. My stack is close to 5 buyins, and my opponents are waiting for an opportunity to trap me. The lady in this hand seems to be my most sensible opponent; she doesn't fall into the trap of playing big pots with marginal holdings, raises draws against me on the flop, and lets me do the betting when she has a big hand. (My stack is big because the others do the opposite.)
She has about $150 behind, and is in the BB for the hand. SB has only $10 and is a poor player.

The hand: I get [Qs][5s][4h] on the button and raise, as I do with 90% of my hands. SB and BB call.
Flop: [Qd][6h]. SB leads for $1. BB calls, I raise pot. SB pushes remaining money in, BB calls, I call.
Turn: (3 players, 1 allin, pot=$30). . Now the BB leads for $20 into the $30 pot. What's my plan?

Note: my read on SB is that he has either the nut flush draw or made a frustration call with two pair.

if you don't put her on KK, I raise pot. If KK is a possibility with the nut flush and two pair, i think i may call here and see what happens on the river.

Raise flop.

Raise turn. I think giving a free card on the turn isn't great here, regardless of how deep the stacks are.
