I think everyone here would agree that 3...g5 is playable but you seem determined to prove that 3...g5 is best. You mention Stockfish chooses 3...g5 implying it must be best. It's not that simple. If Stockfish always knows the best opening moves then why are there so many 6th move options for White against the Najdorf Sicilian? Why don't all the GM's just play whatever Stockfish chooses on move 6?
I am not trying to prove it is the best. I am arguing that it isn't an "olden" move. It may have been a frequently played move out of research experimental reasons, but it wasn't to go to move at top tournaments or matches for titles. Good players knew NOT to play it against other good players. Nothing more, nothing less.
"Agadmator meant a specific period, one that anyone who has studied the history of chess is familiar with: 1850s, 1860s, 1870s, 1880s."
Then present the games. Show me a game where they played g5 in a high stakes tournament? If it is played like the example I gave, it was only played 1% of the time.
"And because what he said is correct enough already and is common knowledge for anyone familiar with the history of chess."
LOL, yea, if you don't provide proof. Let's see how this is established theory back in the 1850's then. Show me the theory. I don't see it. It may have been played a lot, but not in high stakes games. this is the part you are missing and that is NOT common knowledge. There is no wikipedia page or book that has g5 as the top move from olden times relating to top chess players back in the 1800s, and I doubt KGA was even a top opening in a top tournament in the 1800s. Is there one single source? Please share.
All I am asking for is one high stakes tournament where KGA was played more often than the Italian. Show me. Make me eat crow.
"Also, the current COVID numbers give plenty of reasons for alarm, and there's no shortange of analyssi from public health experts to back that up."
There were 606,880 deaths of cancer patients in 2019. The current Coronavirus death count is 132,000.
Why aren't you more alarmed about the cancer deaths? Because it isn't reported in your face as much. So, no need to worry right?
