Please help me how to correctly refer to the following player flaws:
(as I am not a native speaker)

Type 1:

Betting so much with strong hands that only stronger hands can ever call.
Examples:
- 3-barreling AA on 987xx rainbow board
- barreling on with a set when an obvious straight/flush (or even 4 to it) comes in
- 3-betting an underfull on the river

Is this overvaluing or overplaying or both?

Type 2:

Raising the virtual nuts so that no draws can ever call ("protecting my hand")
Examples:
- 10x-ing a preflop raise with KK (to avoid A on flop)
- Raising the Turn with trips when a BD flushdraw comes in.
- jamming 1.5pot on dry flop with top pair or better

I always had the impression that this should be called overplaying, but people use that term for different things. So what do we call this?

Type 3:

Frequently calling 2 barrels with 2nd pair or A high.

Should be over-calling, but that term is also used for a second caller of a bet.

Type 4:

Bluffing too much.
This should be easy. Just calling it over-bluffing

Type 5:
Can you think of other scenarios/uses of the words overplay/overvalue or of other terms?

Poker players like making words up. Sometimes they evolve into a commonly used phrase that has an underrstood meaning, sometimes they are ambiguous.

User the word 'over' to describe an action in poke is one of those cases that can be confusing. Over can mean the following

1. To do something with a higher than optimal frequency
2. To do something with higher than optimal degree or aggression
3. To do commit an action ontop of another action (this is less common, but you will hear it now and again)

Overplay is great example of ambiguous usage. Typically, it means, or should mean, that you played too aggressively and did not get the action you desired. But it is also commonly used to mean that you played when you shouldn't have played, and got trapped as a result. Usually, you can tell from context what meaning the person meant, as they describe somewhat opposite situations.

Overbluffing usually means bluffing too frequently, but I have also heard it used to describe bluffing again (either on a later street, or as a 4-bet or 5-bet).

When I hear these terms, I try to understand, from context, what they mean. i tend to try and avoid using these words, unless the meaning is clear and commonly accepted.

1. Overplaying and overvaluing are basically synonymous there.
2. Both terms also work there, but I'd sometimes call it "Value-cutting" or "value-owning" yourself, when someone chooses large sizes that fold out worse hands and only get called by better.
3. Call it "being a calling station", or "stationing".
4. Bluffing too much is indeed "overbluffing".
5. I tend to use "overplaying" for when the pot gets way too big for a particular hand strength. e.g. If there's betting action on all 3 post-flop streets, or even a raise somewhere, and the player just has one pair. If it's a big pot, but a small hand, then it's probably been overplayed, or overvalued.

See a lot of tilt overplay at lower stakes. Like opening AQo after losing a big pot, getting 3bet by a tight range and 4betting with a large size, then barreling off on any texture that contains a Q.

Also see a lot of overvaluing, 3betting missionary two pair on AJQr flop, calling 4bet turns with marginal sets, two pair or draws. Shoving medium flushes etc.

Type 2 : should be over betting, although here we are refering to size not frequency. Perhaps over sizing would be more accurate.

Type 3 you can refer to as calling too loosely.

Let's not forget the savior words of all poker players ... polarizing and leveling!

Type I ... pretty much interchangeable. I wouldn't totally tie this to betting. You can 'over' a hand as a caller as well.

Type II ... Some call this polarizing, but that doesn't apply unless you have some bluffs mixed in there. Most would call this 'scared money syndrome'

Type III ... Station

Type IV ... LAG, spewtard

Don't forget 'cold' ... as in Cold Call or Cold x-bet when a 2nd Player acts on a raise during the first 'lap' of betting on any given street.

Also toss in a few 'reps' ... as in over or under-repping your hand (also included in the polarizing theme) ... GL
