Vincent,

Here is a PGN of the research I have done with Stockfish of all 3 of the moves that you asked about. A lot of times I had to guide Stockfish on Black's moves and some of White's moves because it didn't understand (as most chess programs don't seem to understand) the position and therefore made seemingly (to me) inferior moves. Of course I am open to ANY suggested improvements for Black or White on any of the moves I have in this PGN, and of course any suggestions that are not in this PGN.

of course I tried several different replies for white including 20.Qc1, 20.Qa1, 20.Qb1, 20.Qc2, 20.Qb3,20.Qa4, 20.Nxg6, 20.Nfe2, 20.Nce2, 20.Qe1, and 20.f3. I have come to the conclusion that all replies by white lose no matter what. The gentleman at the end of the 6 year old thread named "Mischa" had it all correct as to what Fischer's winning plan was, also it must be pointed out that Fischer himself says the 19.bg4!! wins.

No program solved it then, and none of the programs I have tried to date have ever solved this position (including all of the new ones e.g. Komodo8, Latest Stockfish, Critter, Houdini 4, and Gull 8).

Outstanding Milton, and thank you for the post! I never thought to give this position a try with a newer version of Stockfish. I'll give it a try myself and see what happens, once a gain thank you.

Indeed, I can confirm that Stockfish does find Fischer's 19...Bg4!! after slightly less than an hour on my 20 core dual xeon (only using 19 cores) with 16GB hash table and the latest dev version of Stockfish

I often point negative sides about Stockfish but it improved a lot with time.
Tremendous work done !
