Numerical criterion of aggressiveness

Players speak a lot about aggressive openings here, so I decided to give a numerical criterion to this notion. 

Definition 1. The aggressiveness of a chess position, denoted by agg, is the number of direct attacks on adverse pieces. It can be naturally divided into white and black parts and I'll write agg=agg1+agg2.

Example 1 (Falkbeer countergambit).

Here agg=4=2+2, all four central pawns are under direct attacks.

Example 2 (Traxler counterattack).

Here agg=5=3+2; pawns e4, f2 and h7 are under simple attacks while the pawn f7 is under a double attack. 

Have you calculated these values (positional evaluation, aggressiveness, etc.) for large segments of known opening theory as of yet?

Nope, I've just got an idea how to define it yesterday. 

Off topic, but U are wrong, cf. my daily stats  in the previous post. 

In example 1, shouldn't white have a higher score because white is to move? Maybe give white +1, if it's white's turn to move, and if some aggression going on? I vaguely remember something early in Nimzowitsch's "My System" where he recommended an aggressive pawn move by white, similar to 1, something like Scotch opening, but did not recommend it by black 'cause he was a move behind. People here seem to be saying white has advantage:

"the falkbeer is under a cloud and is not so good ... better is to play 3. ... exf4! (modern defense) in which white can barely equalize"

With this agg1 = agg2 = agg = 0 and Black has a pawn! Looks good for black! (position score might not be so good...)

The Nimzo-Indian is aggressive, but it attacks White's structure rather than pieces - I think this should be taken into account. Also it doesn't consider king safety - something like the King's Indian can be aggressive without attacking pieces

Soni, what do you mean by "attacks white structure"? Surely an attack on structure is simply an attack on pawns, and attack on pawn's is dealt with by Yigor in example 1. Could you provide an example board and show exactly why Yigor's method doesn't work?

@Mal_Smith

There isn't much material being attacked here, but nonetheless black is playing aggressively

Everything which the OP ever wrote is a complete joke. Look what the stat prof proposed agg=agg1+agg2, oooh such advanced mathematics look at that, imagine adding one meaningless number to another to get suprise, another meaningless number, lol

I like how you are attacking the OP's idea. It's just a simple idea to start developing the formula

The only meaningless thing here is your existence and comments

You don't have to look far to see that the Falkbeer countergambit gets agressive fast. In fact just look at the MAIN LINE:

It's not my formula LOL but unlike you I don't act like an expert and despise everyting I see

It leads to many things but not immediately. 

The worst thing about you as that you will never realize how much of an ignorant you are...

They say, the more stupid you are the less you realize it

Btw I have seen your daily games... 39 wins and a draw... best move almost always... anything to say about that?
