Any more news, yanquis?
Been running ltc (classical otb) vs SF10, but only partly to get an idea of strength. I do believe test30 does scale well and is close to SF10 head to head (~20 draws in as many games so far, which has been a big surprise) but I am curious, given test10s issues, if test30 can win games against top tier but significantly weaker competition, so I might switch to SF8 for a bit.

I can't read articles written by the general press about highly technical topics such as artificial intelligence (and its fruit fly analog, computer chess).
As a result, it [Stockfish] is not a particularly elegant program, and it can be hard for coders to understand. Many of the changes programmers make to Stockfish are best formulated in terms of chess, not computer science, and concern how to evaluate a given situation on the board: Should a knight be worth 2.1 points or 2.2? What if it’s on the third rank, and the opponent has an opposite-colored bishop?
Totally wrong. I don't participate in Stockfish development but I do know the engine developers are not focused on evaluation. Most of the engine's strength is derived from it's highly optimized C++ code and advanced alpha / beta PVS search algorithm. You know, computer science.
