bottom 2, don't know what to do

[johnnycakes]

The CO in this hand is solid. 20/10/2

MP2 is 15/10/1.4

On the flop, the plan was to bet/3-bet, but by the time the action got back 'round to me I wasn't sure how good my hand was.

<font color="red">What hands can you put these players on?
MP1 could have a wide range. A or J or better.
MP2 could have any A or 9T or a set, right?
Then I figure CO would 3-bet any hand he can't fold, which includes any A. He could have limped with a fairly wide range of hands when it was 3 limpers to him PF, correct?</font>

<font color="red">Now, MP2 donk bets. Did that K improve him? KJ?
And CO now just calls.
I definitely can't raise and the pot's getting big, so I go into call-down mode.
Man, I hate feeling lost in multi-way pots.
