It is a good sign.Losing the initiative in 6 rounds isn't a good sign, for the game itself. However it is a good sign for Lv, who instantly well understood this position and therefore similar positions. You may blame him for making such an opening in this game, but you won't see him making this mistake again in the future. Our views appear to be on the contrast sides, but we are talking about different things - you talk about right now, and I talk about 2 months later.
It depends.
If Ruizhan is planning train with non mainstream opening to improve his understanding of opening theories, then it is good in the long term as he would be able to play better against opponents who play horse or elephant openings. But if he plans to play 单提马 in the competition two months later, then it would be a risk to take. We all know that 单提马 is a defensive opening and it does not suit ruizhan's attacking style. Moreover, two months is too short to convert an attacking style to defensive style.
