I´m doing a research about how different conditions or situations affects the decision making process in chess. for example if the opponent ELO ranking affects the average time used for every movement.in the example, both variables are numerical and easy to know. However I´m struggling when it comes to define if a move is more passive or aggressive (specially after the opening theory).
I noticed that independently of playing style, there are some external factors that make us play more active (aggressive, taking more risk) or passive (defensive taking less risk). I read some articles that says it depends of the current position and the analyzer "strength" to determine with certainty, but that is too subjective for my purposes. there must be some some objective cues to help me.
I was thinking about the mobility (as in how many movements the player or the specific piece have after the last move) or/and if there is making or stoping a threat. what do you think? if there in other cues or method I could use to define if a move is passive or aggressive?
is there a software where I can analyze a complete game and give me this kind of output? Perhaps not if the movement was aggressive but maybe if it is making a threat or reaching more mobility than before
I also know that some softwares like chessmaster, use Ai "personalities" and some make passive or aggressive movements as their traits. can someone explain how the software choose a move that may not be the optimal but a passive one?
Ps. I´m sorry for the long explanation and I´m sorry if I made some grammar mistakes, English is not my first language.
thanks in advance
