The game deviated now, so it's not really relevant anymore, but I'm still curious what people think.
Would this be cheating?

If I'm playing a game that's exactly following the moves of one of my previous games, and I went back and ran my previous game through the computer, knowing that the information would be useful in my current game, would that be cheating?
Yes, using computer analysis on a position that matches an existing game would be against the rules, regardless if that position was also from a different game.

Some strong correspondence players have been banned for this...
In general I fully support chess.com cheat detection, but for seasoned correspondence players, who already have years of engine analysis in their very deep prep (for example 30+ moves), they can get banned without actually being bad guys... sure they're playing exactly like an engine, but that's what happens
So people like that can't play correspondence here (or they have to play on their own), which is fine... but yeah, you'll get banned for it.

I have evidence that top GMs do the same thing. It's unfair that us patzers shouldn't be allowed the same.
Here is the proof GMs cheat.
Aren't they accessing previous games they played too?
Why is Carlsen sitting all by himself? Is he imagining a world around him without competitors? I call this blatant cheating!!!
Grischuk has you all convinced he is wasting time on the clock making a move, but in reality he is playing at a casino in another universe.
Fabiano writes down the moves before he plays them. That is why he is not good at blitz.
Then people like Ding Liren have to look at their cheat sheet on the floor to see what to do next after they win.
It's all there guys, proof is in the pudding. GMs cheat too.
Good thoughts, thanks. I should've been clear -- I'm not actually doing this. But I was playing a game that followed a previous game of mine and the question popped into my head. It was still pretty early in the opening. Maybe it's a grey area.

But let's be honest guys. If you type "2+2" into a calculator are you really cheating to find out the answer is 4?

TBH good correspondance players are centaurs now, or at least that's how the ICCF works now. I love it.

If calculators aren't allowed by the rules then yes.
Does that mean I have to cut off my fingers?
