Grandmaster Ben Finegold has some thoughts on how you ought to play chess.

In videos and lectures Ben shares nuggets of advice which he calls his rules, including the rule never play f6. The rules are generally helpful - f6 does often weaken your king - but of course they aren’t right for every position and are sometimes downright silly. Never play f6 is an overly-broad tongue-in-cheek suggestion, not a rule.
