As an amateur chess player, I have been pondering this question for quite a bit now:
In case of an amateur playing against a Grandmaster, what strategy would lengthen inevitable defeat?
I am assuming that a Grandmaster will always beat an amateur; I suppose that it is possible to find exceptions, but they will be so rare as to be negligible. My question is partly constrained by the following observations:
The amateur will have a significantly higher chance of not choosing the best possible move in any given situation.
The Grandmaster is playing as if they were playing against a Master or another Grandmaster.
In this case, will the amateur be able to lengthen their defeat by always playing what they believe is the best possible move (which the Grandmaster is likely to anticipate with experience), or by using strategies that are not encouraged but objectively make the game more difficult for the Grandmaster (eg. always going for the kill regardless of piece value, a queen for a queen)?
Or would it benefit the amateur to play an entirely random move every turn, since it would prevent the amateur from taking the bait/accepting the gambit?
