The last video listed (""), by GM Cemil Can Ali Marandi, is particularly interesting, and quite good, and I point it out - to those who want to know how to meet the Jerome Gambit, and for those who want to prepare for when they play those who take the grandmaster's suggestions.
The next-to-last video ("Das Jerome Gambit || Das schlechteste Gambit im Schach?!"), by GM Huschenbeth, is also good, although it helps if you know a bit of German.
