One thing I do to discourage min/maxing is letting PC's suffer the consequences of dumping ability scores. things like enforcing carrying capacity for low str, creating situations where many different skill checks are required, and hitting them with a variety of saving throws.

Also PCs with low mental scores will suffer in social situations. Low cha PCs will be shunned, low int/wis will be taken advantage of (higher rates in shops/taverns, being bluffed regularly into believing things that will get them into trouble)

most of it is just adjusting encounters to the party.

On the other hand you should also give them the opportunity to shine. Give them some encounters where their maxed out ability can make a difference

If this was a new player I would cut him some slack, but if it was an experienced player I would expect him to know how the spells/feats/abilities his character uses, and I would hqve done the same thing

Pugwampies

having to roll every d20 twice and taking the lower gets very annoying.
Even for a level 5-6 party a group of pugwampies with some cover can really be a pain in the @$$.

I once used a room with some animated objects in the first room of a dungeon, and it caused the party to start systematically smashing all the furniture they encountered in the rest of the dungeon, just to make sure. Paranoid players are so much fun for a GM
