Hi, good morning,
next match is rather classical, between two more or less closely related Fidelity Electronics devices: Champion Sensory Chess Challenger vs Sensory Chess Challenger 9b. Both are powered by a 6502 close to 2Mhz, the 9b born two years later has a slight theoretical edge program-wise. Nevertheless, the Champion deserves its name and is very successful: 2 points!
The first game is rather tactically complex to my eyes; the Champion gets an advantage smartly coordinating two pieces (N+B) while the 9b struggled to defend with its single Rook.
In the second game with opposite castlings, the 9b fails to take enough care of a pending strong attack from the Champion; its own attack it tried to develop on the other side of the board hanged fire.
