Fritz vs Junior – Game five

Game five was another complicated game. After the opening Fritz evaluation was half a pawn up and it stayed there until the end of the game. As so often in this match Fritz had a couple of pawns for the exchange, but it did not suffice to win the endgame. I congratulated the Junior team for winning the match and hope that tomorrow with white Fritz can play for a win. – Alex Kure of the Deep Fritz team.

Deep Junior begun with 1.Nf3 and the game evolved into the semi Slav opening. When Deep Junior departed from its opening book it was forcing a variation where Deep Fritz had to sacrifice quality preserving a pawn mass on the queen side. Both programs disagreed with their evaluation when assessing the position. Deep Fritz felt it had a comfortable advantage while Deep Junior believed the position was balanced. In move 22 Deep Junior sacrificed its f-pawn to obtain direct threats against Deep Fritz’s king. Deep Fritz defended by exchanging queens. The endgame obtained was still looking good from Deep Fritz’s perspective, and the disagreement between both programs continued. Only after Deep Fritz advanced its pawns it realized that White can force a perpetual check and by avoiding it Deep Junior could sacrifice a knight for two of Deep Fritz’s dangerous pawns. Alex Kure, Deep Fritz’s operator offered a draw which was accepted by the Deep Junior team. – Shay Bushinsky of the Deep Junior team.
