Rd. 17.1  Stoofvlees 0-1 Dragon

Only 2 1/2 minuets on my Ryzen 16 threads but Stockfish gets the picture (as in Dr's PV at TCEC also) :

32.Ra6! is the only move to survive, though at a disadvantage.

Amazing, after playing the Muzio Gambit at the diagram white is down a R + N for only 2 pawns !?

Stoofvlees lost at TCEC after 32.h3??

Is it possible to get FEN from your post?

> Is it possible to get FEN from your post?


Sorry, I am not sure what you are asking.

The original game has FEN options on TCEC's site:
https://tcec-chess.com/#div=if&game=17&season=21

Then the game my post is Stockfish's analysis PV=4 for white's move 32:
the main variation 32.Ra6 which Stockfish says is best, white advantage but not winning,
2nd 32.Qe2, 3rd 32.h3 (played in the TCEC game), 4th 32.h4 all have ?? because Stockfish gave them essentially losing evaluations.

To get a FEN from my forum post "game" -the Sf analysis, go anywhere (click a move or the controls on the bottom: << is for before 32.) then click the b8 square and the FEN for it pops up in a new window.

Thanks. It is what I needed. I did not know about clicking the squares.
