Win and Lose With the Bishop Sacrifice Gambit!

Yury V. Bukayev directed me to Michael Tam's "Adventures of A Chess Noob" website, subtitled, appropriately, "learning and having fun with chess!"

In particular he wanted me to see "Win and lose with the Bishop sacrifice gambit!" This was not a particular opening, but, as Mr. Tam pointed out, a thematic idea that can occur in a number of openings. "This is best characterized by the Jerome Gambit" he says, although he adds "The Jerome Gambit is completely unsound, I don't recommend it."

The rest of the video is Mr. Tam showing two games, one where he  defended a Two Knights defense and one where he played a Vienna Gambit. Both featured the Bishop sacrifice.

He sagely suggests that you make the sacrifice "only if you have an immediate attack that can take advantage of the exposed King". That has always been a criticism of the Jerome. (It is also why White often follows 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 with the further sacrifice 5.Nxe5+ and attack, i.e. 5...Nxe5 6.Qh5+)

I recommend visiting the site (with some stunning graphics), which has many videos about many openings, and especially watching Mr. Tam play over the second game, the Vienna Gambit. It is truly wonderful to hear Mr. Tam talk about how Stockfish continues to rate the defender as doing far better, move by move, even though you are watching the pieces on the board and you know that you are seeing him crush his opponent.  

Happens in the Jerome Gambit, too, I have to add.
