I’ve edited the following sgf https://online-go.com/game/84231872 to this
but after exporting the sgf and trying to load into aisensei I get the error Error: Add White not allowed in SGFs
I’ve also tried converting the above image to sgf and I can load it into ogs but I cannot make moves in the following sgf https://online-go.com/game/84232615.
It seems you added and removed stones ‘randomly’, like it wouldnt be possible in a rral match. Most, or at least some, programs can not deal with that. They can only deal with positions that can be created within the rules of Go. Means alterning moves of black and white, no stone removing and so on. You get what I try to articulate?
So, your Sgf itself may be fine but it can not be interpret correctly.
Edit: The same applies if you take a photo and let a program make a sgf. Because they usually add the moves from left to right and top to bottom. The program doesnt know the order of moves obviously. And Ai sensei now wants to interpret the moves made the way the program added them to thr sgf rather than the final position.
Katago can analyze the files. More generally, you can enter any board position and it finds the best move from that.
