Interesting game featuring a very casual and positional exchange sacrifice as well as a dancing knight. Towards the end black is basically in zugzwang and starts dropping material in desperation.

Yes, that was a fantastic game by Deuterium! I think the sacrifice was 100% correct, but Deuterium didn't find the optimal way to proceed, so SF starts to prefer black, but in the end Winter was the first to slip up. Was a fantastic fight and well deserved point that may decide the tournament!

In general Deuterium's aggressiveness has impressed me a lot. In a field filled with engines that give me more of a positional vibe, eg: Marvin, Scorpio and Winter, it is definitely a nice change of pace.

Congratulations to both Ferdy (Deuterium) and Jonathan (Winter) for sharing top spot.
Both engines will promote to Division 3 for the next series.

It was fantastic seeing many of the engine authors (and others) in the broadcast and chat.

Thanks for the event Graham! Was a really great struggle at the top and some other engines were really looking good. SlowChess and Scorpio looked especially good when things were going well and Minic won against a lot of the first half of the field in the last round robin, including one of the winners!
