These questions confuse me. The Analysis board clearly has Stockfish 14.1 +NNUE. (Or, it does on my browser, anyway - which is Microsoft Edge.)
I also checked on Chrome, and it's there, too.
Go here to see if you have it:

Click on the Settings (gear icon) at the top right of the board, right next to black's rook:
It'll open a window that shows you the version of Stockfish that the analysis board is using:
ans me
Can you show me a single position from any of your games where Stockfish 2 would have proven inadequate?
