Is this a conjecture or a theorem?

In a game of 6 Hours per side, houdini is so powerful that it can beat Carlsen even if he takes any 3 moves back during the game

A better question, could Houdini beat Carlsen 12 out 12 games, without Carlsen even drawing 1 game? I think yes.

I think that you are overestimating Houdini, remember that Houdini nor any other program has played versus any GM over 2750 with a long time control of 6 hours per side.

PS: There are a lot of positions that neither Houdini nor Stockfish can evaluate correctly and eventually will play an inferior move. All that Carlsen has to do is slowly force one of those many positions and B A N G *%$#&^*($^#$#)** And Houdini would be without a clue of how to continue

Or Carlsen could force a quiet and drawish opening, or he may try some anti-computer strategy.

A lot would depend on the book the engine is allowed to use.

Houdini will never have a blunder big enough for Carlsen to capitalize. But Houdini will capitalize on every one of Carlsen's blunders. Just look at the championship just finished today. Carlsen blundered away a win. Carlsen cannot accurately look ahead 30 moved. The computer sees beyond the Carlsen's horizon

Now look at my initial thread, I said that Carlsen could take back any three moves during the games, just in case that he blunder

Which move would Carlsen take back? To Carlsen these are not blunders. All carlsen's sees is that he is losing after 30 moves. Carlsen will wonder where I went wrong. A blunder for Houdini is not the same as a blunder for Carlsen.

Yes, but a position like this one Houdini to play with white will have a hard time to find the draw without using a tablebase:

This is the correct solution for White to find a Draw:

1. Nf5+Kd8 2. Ra8+!(2. Nxd4a2 3. Rb7a1=Q 4. Rxb6Qxd4 5. a7Qe5+ 6. Kg2Qd5+ 7. Kg3Kxd7)
2... Kxd7 3. a7 Ra4 4. Rg8!! The only good square for the rook. The reason will be revealed next move.
4... Rba6 5. Nh6!! One of the most amazing moves ever, but stockfish evaluate this position as -6.30 give me a break, in some position engine are useless! White is threatening perpetual check all along the board, and black is unable to prevent it!
5... Rh4+ 6. Kg3 Rha4 7. Kh2 etc...

The answer is no. How do you think Carlsen became such a powerful player?

He trained against computers all his life. He plays like a machine as he was able to adopt such powerful tactical abilities from computer chess.
