Based on results we have seen in both normal chess and chess960 when powerful hardware is used with NNUE engines, unless bad openings are mandated, the draw percentage between roughly equal NNUE engines at long time controls is in the high 90s, basically making the game unplayable. So what is the experience of correspondence players using good hardware and NNUE engines over the past six months? I suppose some games are won due to opponents having inferior hardware or not knowing about NNUE or not caring about the result much, but is anyone winning any games from opponents where these factors are not applicable? Is correspondence chess still playable without mandated openings?
I am currently analyzing interesting openings extracted from Millionbase 3.5 and Correspondence 2, together 5.5 million games. I am almost finished the gambits part and moving to popular openings. My question is, what are the popular openings of correspondence players?
