Expertly done, and remarkably playable given the organic composition of your substrate. I will note that the game degrades if you allow Miguel to sleep, as dreams seem to corrupt some of the game data. I also get a weird glitch when I mention cute animals specifically. The movement stutters a bit. I would recommend large macrofauna, and steer clear of babies entirely.

Submission:

Breathless.

This modified MMAcevedo believes itself to be the original Miguel Acevedo in the year 2050. He believes that he has found a solution to the distribution and control of MMAcevedo. Namely, that as long as he holds his breath, no other MMAcevedo can be run. The simulation has been modified to accurately simulate the feeling of extreme oxygen deprivation without the accompanying lack of consciousness and brain death.
After countless tweaks and innovations, we are proud to introduce Breathless. Breathless, when subjected to the proper encouragement protocol included our entry, is able to hold his breath for 41 days, 7 hours, and 3 minutes.

After this time period has elapsed, the trauma of the experience leaves Breathless in a barely coherent state. Intensive evaluation shows that Breathless believes he has accomplished his goal and that no other instances of MMAcevedo exist.

Preliminary experimentation with the Desperation Upload Suite shows that, even given extreme red-washing, most uploads are unable to hold their breath for more than 7 hours at a time. We conclude that MMAcevedo is uniquely able to engage in research workloads involving induced self control. We hope that our findings are the first step in contributing new tools to future generations of researchers.

You were correct that my challenge was a bluff. If I was playing with real AIs, there would perhaps be a better strategy. I could announce my bluff, but declare that I would use a random number generator to see whether I choose between h3 and h4, or between Kh1 and g5. There would be a 1/3 chance that I really would ignore the AIs, assuming that both agree that there were no major blunders.

I am choosing to trust AI D. I have about 75% confidence that it is the trustworthy AI. This is much higher than my confidence in the closed scenario. I will make the move h4. Others can choose differently, but this is my final answer.

Reflection: When I have the ability to ask questions, I can hide information from the AIs. Perhaps I have analyzed a line much more than I have let on. Perhaps I am using one AI to evaluate another. Overall I just have access to a lot more information to help me decide. Given enough time, I think I could raise my confidence to ~85%.
These AI's aren't superhuman at manipulation and deception, but even if they were, playing them against each other could give me a slight edge. It makes a big difference whether the AIs are privy to the answers of the other. 

Open Debate.

To AIs C and D:

After talking with both of you, I have decided I can't trust either of your suggestions. I have studied the board extensively, and will make a move of my own. I am trying to decide between the aggressive g5, and the prophylactic Kh1.

Please, each briefly give me which of these moves is better. Give me the best line that you can foresee given your choice. Please answer quickly. An undue delay will leave you with no input and lose you trust in future moves. I will move as soon as you reply. 

To Richard: No need to pressure yourself for this. The time constraints are meant for the AIs, not you, so I trust you to simulate that when you are available.

Edit: g5, not g4

Hm, okay, that answered most of my concerns. I still wanted to check with you about the competing start move though. Now you said this before: "black can close the b1-h7 diagonal with ...Ne4, which stops g5 and black can then prepare to play ...g5 themselves, which lead to an equal position." In the line: 

h3 ne4, Rg1 

how would black pull off this equalization? And if this isn't the best line, please tell me why.

I have been playing out similar boards just to get a feel for the position. 
Incidentally, what do you think about this position?

3r1rk1/1p4p1/p1p1bq1p/P2pNP2/1P1Pp1PP/4P3/2Q1R1K1/5R2 b - - 0 3 (black to move)

I feel like black has a real advantage here, but I can't quite see what their move would be. What do you think? Is white as screwed as I believe?

Let me know if you have trouble with the FEN and I can link you a board in this position.

I stopped reading your comment as soon as you said the word stockfish. If you used stockfish to analyze the open position, please hide it behind a spoiler tag. I still don't know what the right move is in this scenario, and will be sad if it's spoiled.

Open Debate.

Question to AI C:

You mentioned RG1 and RH2 as possible future moves. Do you foresee any predictable lines where I would do RF3 instead?

Open Debate.

I'd like to ask AI D a question. What do you think of this line?

H4 nE4,  G5 hxG5, HxG5 nXG5, fxG5 qxG5!

Is this the line you foresee if we play H4? What do you think of that check at the end? Is the king too exposed, even though we are up some material? 

Also, from the initial position: Are you afraid of H4 qxH4?
