The newly released enhanced version of Pengfei Chess has a built-in C4 chess engine, so I wanted to test the strength of the C4 engine and compare it with Pikachu 20260131. The overall strength is similar to Pikachu, but not as strong. One good thing about it is that it won't be helpless in a circular situation like a pickup truck. There is a problem: its evaluation is similar to that of a pickup truck, but as a free engine, it is not worth considering.
