A couple quick solutions from my simulator.
Here the question is: Do we put trips middle or not? The answer is:
T Bottom, 7 middle: -6.264
T bottom, 7 (or J) bottom: -8.975
T bottom, 7 (or J) top: -9.09
I found it interesting that closing the bottom was better than closing the top, its definitely not my first thought reaction.
Here we have a few options. The answer might surprise you:
K Top, T bottom: -4.525
K Top, T Middle: -4.622
...
K Middle, T Bottom: -6.151
...
K Top, 8 Middle: -8.955
This just goes to show that beating Q high up top is more valuable than we might have thought, and two pairing the middle doesn't accomplish much when our opponent has only 1 overcard out (and running 2P or 99+).
