Good evening all,
now the Fidelity Champion Sensory Chess Challenger encounters the Yeno 320XT.
I trust the first game is a nice demonstration of the horizon effect: after a balanced series of moves, the Yeno performs a mistake that should cost it a Knight (3 points, so).
Well, instead of acknowledging that, it sacrifices a Rook for a Bishop. I strongly suspect the 2 points loss from this operation were considered a better option, assuming the 3 points loss has been pushed beyond the calculation horizon.
And the next move is again a sacrifice, a Bishop for a Pawn. Again a 2 points loss "avoiding" the pending loss of 3 points.
Unfortunately, that only postponed the unavoidable initial loss of a piece; therefore a total material loss of 2+2+3=7 points!! Then, of course, the Champion knows how to win.
The next game with Yeno as White is quickly decided, the Yeno blundered as soon as move 18, enabling an easy mate in 2.
Two points for the Champion.
