Inspired by the computer, many humans try their unusual moves, such as the 5…Bb1 that appears in this game, trading a possible bad bishop for a knight that hasn’t even moved yet. The justification is that the knight will be more useful in the ensuing closed position than the bishop might be; as far as the computer can see, the knight is the better piece. We humans have learned the hard way that if the game lasts to the ending, the bishop is likely to outfight the knight; but at move five the computer has no reason to suspect that an ending will ever occur. Some players play endgames more often than other players; so take your own experience into account when you decide whether to give up the bishop for the knight extremely early in the game. In this game, after the bishop-for-knight exchange, the position is not particularly closed, and the participants split the point.

CONNECTICUT CHESS MAGAZINE
Connecticut Chess Magazine and Coventry Chess Club are each philanthropic enterprises by Rob Roy.
They are not governmental initiatives nor are they business endeavors.
They are private initiatives by Rob Roy, for the public good, focusing on quality of life, and on chess in Connecticut.
They should never be misconstrued to represent the State of Connecticut, the Town of Coventry Connecticut, nor with any other chess associations.
The monthly tournaments in Coventry are conducted by Rob Roy acting as an independent organizer, and not by any chess club, state chapter, nor federation.
I have never written for, nor spoken for, anyone besides myself, Rob Roy, acting as an independent chess journalist.
Rob Roy derives no material gain from these two entities, in contrast; Rob Roy suffers significant monetary loss from their operations.
