			I think the "tactics" that are complained about are more like when a dire weasel threads its way through a party, avoiding all threatened squares, to latch itself onto the sorcerer at the back, who hasn't even cast a spell yet, just to take her out of the fight...
Or once the party has a "line" spell, the enemies stop lining up...
		
		
	 
To a degree, that's metagaming, anyway. 
In regards to the initial post: 
You know, at one point a player of mine was called out on thinking up something particularly clever to the point that it just stood out as something his character's own low-to-average Intelligence wouldn't, as the players who called him out thought, cover. 
At which point the clever player in question remarked on his own lack of intelligence most of the time, to which we all essentially agreed, and promptly left him alone from there on in. 
And, for the most part, that's probably how it should be done. Because seriously, how many people do you know with an Intelligence above, say, 15? And if you were to say that roughly was their Intelligence, how many would you say had a Wisdom of above 15 on top of that? And Charisma? My group is, for the most part, a fairly bright bunch, but all of them lack at least one, if not all of those, ability scores at above middling levels, if I were to slap numbers on them. As such, any bits of insight they come up with for their characters are probably fairly appropriate. 
Besides, how often are their tactics extending beyond small, fairly personal conflicts? Sure, if they start following in the footsteps of Hannibal or Alexander or whoever, yeah, the I might say something if they're the relatively typical low-to-average Intelligence, Wisdom and Charisma fighter. 
But unless the character in question is coming in at under an 8 Intelligence or Wisdom or what not, then the player probably has roughly the same mental capacity. Level, as has been mentioned, also comes into play here and, generally speaking, the more tactical tricks one can pull out, the higher level the character is, anyway.
