In page Latvian Gambit:

"

The name Latvian Gambit is a tribute to several Latvian players who analysed it, Kārlis Bētiņš being the most prominent among them. The Austrian master Albert Becker once published an article that Bētiņš judged to be dismissive about the Latvian Gambit.[citation needed] In response, Bētiņš published and analysed one of his own games in order to defend the gambit: Ilyin-Zhenevsky vs K Bētiņš, 1921.[citation needed]
