Have you ever taken advantage of poor AI?

Have you ever won a game against a computer player purely by taking advantage of poor artificial inteligence? I have!

I remember one time when I played Settlers 3. Whenever I played, I usually played the no enemy map, but there was one time when I played against a computer player and won in the most weird of ways!

I started by (unintentionally) letting my opponent make their base absolutely huge. I then noticed that many important buildings in the enemy base weren't close together like they should have been. I literally beat them with a divide and conquer strategy, splitting the base in half, destroying one half at a time.

In my opinion, artificial inteligence hasn't got all that much better in recent years. I could probably use the same strategy in newer versions of Settlers and still win in the exact same way!

Pokemon Conquest tbh. I defeated the entire game plus the post game minus the downloadable episodes in less than a week twice.

Constantly, play any FE game before FE12 and you'll see it.

Props to FE9 for the weirdest AI.

F1 2014 had some pretty rubbish AI. They never tried to overtake you.

-One of the boss fights in Castlevania: Dawn of Sorrow became very easy if you used a certain ability on some guy that mimics your ability, then attacked with only swords/axes/ etc.
-Same series, Portrait of Ruin, had a "doppelganger" boss that was easy if you didn't equip any weapons or abilities and went "mano a mano" so to speak.
-I remember the zombies in the first Resident Evil (PS version) would lunge at you at a 90 degree angle from where you were facing, so if you rotated then quickly turned another direction and ran they'd completely miss you. Also, the Hunters were easy to kill with a knife if you charged them and kept stabbing their feet. They'd block and growl, but couldn't attack because you'd hitstun them.

Was it something like using a knife or whatever made him trivial?  I remember there was some booby soul magic that you could use that made him not do anything.
