I'm showing up way late to this thread and a lot of the posts are long enough that I've only skimmed them, so I'll apologize if my argument has already been made earlier in the thread. However, the main thing that I'm seeing here is arguments of positional vs. tactical. The thing is that the two can not be separated as they are basically the same thing! The main difference is in length: A tactical move (in the purest sense of the word) uses an immediate tactic to gain an advantage. A positional move sets up a tactic that can't possibly be seen by anyone, but is known by the person who plays the positional move. For example, if you trigger a series of trades that leads to a good bishop vs. bad bishop ending, you already know that you'll win with a series of bishop maneuvers leading to zugzwang although there's no way you can possibly see it yet.
To put it more simply: Tactical play immediately takes advantage of a factor in the position to obtain something, positional play is setting up tactical play before it happens. Even things such as obtaining more space qualify for this: "If I can fix the pawn structure in this way, then after I trade these pieces, I can invade my king on the queenside and win the b7 pawn."'
In my opinion, positional and tactical play can't be separated as the two are completely reliant on each other.
Well stated. I think you are completely correct, except perhaps in the situations where a player has a lost position and he purposely introduces complicated but incorrect tactics into the position. The tactics really aren't based on positional considerations, they are based on desperation. It is his only chance to save the game. Normal and correct positional moves would lose trivially. On the other hand can someone make the argument that based on the reality of the position these kind of moves are actually positionally (but not tactically) sound?
Which it is, to some extent, surely?
It is for me. Sometimes I make a good move based on incorrect calculation. When that happens I feel very lucky. I guess someone could make the argument that my intuition triumphed. Not sure I buy that. Sometimes I just randomly drop my pieces on good squares.
