tactical motives

How can you see from your opponent that he allows tactical motives?

This question is somewhat related to these questions:

How can you see that your opponent plays sharply?
Is playing sharply a sign of allowing tactical motives?

Either you guys are of opinion I think too simple or am too complicated.

The truth is: I am just like you! A regular average guy, trying to get good at chess! Yet, unlike some other chess players, I want to win in a fair way. My questions asked above may seem dubious in that manner but it is something else than tapping with your fingers on the table to make your opponent lose his six deep analysis he was obviously in. Or kicking somebody hard against his shin and telling him right away is was an accident. Or putting the table such that the setting sun shines annoyingly in your opponents face.

Hmm, the question seemed vague so I wasn't sure what you were asking. Maybe this is what others thought too.

In chess the word "tactics" has a specific meaning, for example: forks, pins, and skewers. So when you say "tactical motives" it's unclear what you mean.

IMO a sharp position has two main features. 1) a lot of calculation is necessary and 2) errors are often fatal. An easy example is opposite side castling where both players are attacking at once. An example of the opposite would be a closed position where calculation isn't as useful and inaccuracy isn't fatal.

So "is playing sharply a sign of allowing tactical motives?" I'm not sure. It is a sign of allowing tactical motifs. As for motive, both players often agree on the type of position they will play during the opening. So in that sense each player is allowing the other to get a position they want (by agreeing to play certain opening lines with them). But maybe you have a different meaning in mind when you say "tactical motives?"

Agree with Leiph18, thats its not entirely clear what you are asking... but I've been thinking of what to say of this, and here is the way I think of it.

Chess, is at heart, a game of mistakes.  Played perfectly, I'm confident that every reasonable opening is a draw.

on the other hand, since we are people and not imperfect silicon monsters; we will fail to accurately ensure that our peices (and king) is safe.   If our mistakes are easy- for example the peice is just plain free and ups for grabs- then we usually call them a blunder.

in other positions, we simply can't defend against peice coordination,   attack on multiple targets, pawn promotion,or an attack on a vulnerable valuable peice.   These kinds of moves are called "tactics" because they bring out the vulnverability in a superficially safe positon.

Any good player takes great effort to look for moves that wreck a superficially safe position (and study the patterns that allow you to rapidly see them).

In short-- in your first post, you ask "Is playing sharply a sign of allowing tactical motives".  "YES"

if you open weaknesses in the King- or leave lots of peices hang then this encourages your opponent to play Very sharply.

I'm not sure what you mean about "playing" fair.   it is utterly fair, for your opponent to play strong tactics against you- when you play poor chess and fail to anticipate your opponents good moves.

Lastly, its a little confusing why you are asking these questions?   You are a strong player and play blitz as strongly as I play standard.  a 1450 in any time control should have some solid skills of seeing and taking advantage of tactical weakness.  

joliepa,

The question comes from reading an article in "New in Chess 2015#2" called 'When is the time to calculate?'. Author Parimarjan tells us to switch from normal chess mode to calculating chess mode the moment you see your opponent allowing technical motifs.

Awesome. and that is good advice, yes.

I'm sorry  I really don't know what the question.  If you see a tactical motif; yes you must calculate carefully.  

Are you are mistaking the phrase "tactical MOTIVES" and "tactical motifs" ?

a "motif" is a Pattern- like a knight fork or like a Back row mate. 

the "motive", though is that you play chess to win, perhaps for money or prestige- but mostly for the joy of figuring out how to win in that tricky position.

This could be difficult if we are having difficulties with vocabulary.
