My major achievement for 2021 - 1000 pieces. Comments follow about the power of the subconscious mind v. cognitive overload.
Obv. massive CL to start with, so personal management of CL following analysis is important to get started (edge pieces were not helpful in this case) similar to cryptic crosswords, chess problems etc. (1/n) ...
No point in even thinking about CL really - just get on with analysis and subgoals. Towards the end things got very interesting. Obv. pieces were missing. Systematic perceptual analysis told me they were missing (2/n ...)
Like in crosswords where you become convinced the setter has made a mistake, or in geometry where you are sure the properties must be inconsistent, or you don;t have enough info. (3/n ...)
Then, after a break or a sleep, I would see things differently. My perceptual habits had reorganised themselves and I could see more pieces and places. The CL terms 'spacing' and 'interleaving' get nowhere near this experience of insight after impasse. (4/n ...)
I am convinced that thinking teachers can micromanage this subconscious process by managing input is a category error. Analysis, preparedness, impasse, trust and perceptual reorganisation got me through this. Same as when I do geometry (n/n)
