This is the Semi-Slav, Anti-Meran, Lilienthal Variation (https://www.365chess.com/eco/D44_Queen%27s_Gambit_Declined_semi-Slav_anti-Meran_Lilienthal_variation).

Re: Leela solves the Qf6+!!

If you click through the games starting at #1, the Event label stays the same until they simplify it at Game 10 on, when it also no longer changes, i.e., LC0 is always listed first.
