Most moves in an officially recorded Correspondence Chess Game

Dear All 

Gary Maguire and I just finished our British Correspondence Chess game (2023-2025)

It lasted 136 moves

Out of curiosity, does anyone know of a longer Correspondence Chess game?

If you do happen play through the game, because the game was obviously going nowhere using Stockfish 17, Gary and I made a gentleman's agreement to stop using a computer after move 80, as you can see from the errors that I made 

That being said it was, after move 80, the most enjoyable game

Best regards

Terry

That's the problem we are now trying to solve

In ICCF correspondence chess Computer is obligatory

Try asking Google Gemini the question and it will provide an excellent analysis

Could you post the game on a board? I would love to actually follow this. And yes, ICCF allows engines, which a lot of these type of games are referred to as Centaur Chess.
