Thank you, Dann.

[Dann Corbit]

Thank you, Dann.

Here is a link to my Grob data.
Perhaps a path to a better Grob future can be found:

[Lazy_Frank]

I have tried two times Grob.
At the first moment it is all about to save single tempo by white ...
But sooner or later seems white is a bit to short save that tempo.
When it is lost, it is done. Sad there is one white move (g4) that loses instantly.

[Eelco de Groot]

This last analysis only proves that 15. Nd4 is not playable, even if Stockfish thinks it is . Fruitig (the SE version so not the standard one from Ed) never plays this, White still may be lost but 15. Nh2 is a bit better.
Then some moves that the engines think more or less forced 15...Qh4 16. Nhf1 f5 17.d3
Here Fruitig only considers 17...e3, well it can only output one line and it is extremely selective so take with dozen grains of salt, Stockfish thinks 17...Bd7 much better
