Yes, I think you're correct. The first four moves in the pv are redundant. Maybe I should have let it run a bit more.Albert Silver wrote:You sure? Looks like it prefers c4 to me.Code: Select all

No need as it will play the move. The first four plies seem like an odd glitch in the search.zullil wrote:Yes, I think you're correct. The first four moves in the pv are redundant.
