Hello,
to share more illustration of the resulting playing style (Tibono setting), here are 4 games I selected out of eight the Systema Challenge played, opponents being:
Code:
S.C vs Tasc The Final ChessCard : 0,5 - 1,5
S.C vs Mephisto IIIS Glasgow : 1,5 - 0,5
S.C vs Fidelity Designer 2100 : 1 - 1
S.C vs Saitek Stratos (B) : 1,5 - 0,5
15s/move games, free openings. Opponents being all CB-Emu entities.
Within my private Elo-liste, the Systema Challenge entered the tournament with 1789 elo-points, opponents average was 1788 (so, quite well balanced), and 56,3% success rate achieved by the SC is worth a 1832 performance that will slightly raise its ranking.
Analysis with help mainly from Chess Game Analyzer v 0.12 (Ferdinand Mosca) + LC0, NN LD2, 30s/move
Now, the floor is to the games:

{ The Challenge stayed on par with the Designer 2100 (a strong one, it is a
dressed-up Par Excellence) despite the game being not that simply
positional. And the 2100 surprisingly blundered, grasping a pawn while the 8th rank needed to be defended. The Challenge is weak at tactics, but able
to smell the promising attack. } 1-0
