Anecdotally, the ACKS approach to handling what it calls "special maneuvers" (things like brawling, wrestling, and knocking down, which in the olden days were called pummeling, grappling, and overbearing) has proven to be quite popular among the old-school "Classic D&D" crowd (those playing, e.g., B/X or one of its clones). Here's the method:

Suppose an attacker wants to "wrestle" his opponent. The attacker makes an attack roll at -4. If it hits, the defender rolls a saving throw vs. paralysis: if he saves, the attack is negated, and if he fails the attack succeeds and the defender is grabbed in a wrestling hold. So, attack roll, saving throw, end of story. Simple as could be, which explains its popularity.

Unfortunately it breaks down on closer inspection. The math just doesn't hold water. Let's say we have two opponents, Boris the Blowhard, 1st level fighter, and Urkel the Unimpressive, 1st level mage. Both have average ability scores, so there are no bonuses for STR or DEX to consider. Boris ends up in melee with Urkel, but having previously lost his sword, finds himself only with his bare hands. He therefore attempts to wrestle Urkel to the ground before he can fire off his sleep spell. Urkel, as an unarmored mage, has AC 0 (ACKS has its own version of an ascending AC system, with AC 0 being the equivalent of AC 9 in B/X). Boris, on the other hand, has an Attack Throw Value of 10+, meaning that he needs a 10 or better to hit an unarmored (AC 0) opponent.

However, when Boris attempts to wrestle Urkel, he takes a -4 penalty to his attack roll, so he ends up needing a 14 or better to succeed. Thus, right off the bat, we have a situation in which a 1st level fighter has only a 7 in 20 (35%) chance of grabbing hold of a 1st level mage. But it gets worse, because even if Boris rolls a 14 or better, Urkel still gets his saving throw, and 1st level mages save vs. paralysis at 13 or better. So, the chances of Urkel failing his save are 12 in 20 (60%). This means that a 1st level fighter's overall chances of success at simply grabbing hold of a 1st level mage are 35% x 60% = 21%, or just about 1 in 5.

So Boris fails, but it turns out he's just a henchman for Lord Rhothar the Redoubtable, who steps into the fray to lay a hold of this nuisance of a mage and choke some information out of him. As a 10th level fighter, Rhothar has an Attack Throw Value of 4+, so normally he needs only a 4 or better to hit an unarmored opponent, but since he's now attempting a special maneuver, he takes a -4 penalty, so he actually needs an 8 or better, meaning that his chances of success are 13 in 20, or 65%. But again, that pesky Urkel gets his saving throw, so Rhothar's overall chances of getting him into a wrestling hold are 65% x 60% = 39%, not even 2 in 5.

Perhaps the most obvious fix to all this is to simply get rid of the -4 penalty to hit. Unfortunately that just isn't sufficient. That would give Lord Rhogar an 85% chance of landing his initial hit (17 in 20 instead of 13 in 20), but with Urkel still having a 40% chance of making a successful saving throw, that puts the overall odds of Rhogar's wrestling attempt being successful at 85% x 60% = 51%. So a 10th level fighter would need to flip a coin to see if he could grapple a 1st level unarmored mage! This won't do. Some other method is needed.
