One more test? Original position, Black to move, Knight back on a7 but this time White's Knight on e2. Thank you.
Engine gives white an edge but not a clear win, in this kind of position engine evals are not always reliable if a clear win is not found. Black will probably win the c-pawn after Rb4 but white gets pretty good play with the knight coming to g3 and possibly h5 targeting f6 and also with the rooks along the e-file.
Plus it's too late as I already gave him the trophy
:(
