The first time I sat in a live game, the table might as well have been speaking another language. Someone was "under the gun," another guy "three-bet the cutoff," the dealer asked if I wanted to "run it twice," and when I lost with kings I was told it "wasn't even a bad beat, just a 
cooler." I nodded like I understood. I did not.
Poker has its own vocabulary, and knowing it does two things: it stops you looking like a 
fish, and it lets you actually follow the strategy that makes you money. This glossary collects the terms that genuinely come up at a Texas Hold'em table — grouped by how you'll actually run into them, not just dumped in one giant A-to-Z wall. Start with the terms people mix up most, then browse whichever category you need. Where a term has a full guide, you'll find a link straight to it.

The Terms People Mix Up Most
If you only clear up a dozen terms, make it these — they're the ones that cause the most confusion (and the most costly mistakes) at the table:
| These get mixed up | The difference |
|---|---|
| Check vs Call | A check risks no chips (only when no bet is live); a call matches an existing bet. |
| Blind vs Ante | Blinds are positional forced bets (SB/BB); antes are paid by everyone to seed the pot. |
| Set vs Trips | Both are three of a kind — a set uses a pocket pair; trips uses one hole card + a board pair. |
| Cooler vs Bad Beat | A cooler = you were behind and couldn't fold; a bad beat = you were ahead and got outdrawn. |
| Value bet vs Bluff | A value bet wants a call from worse; a bluff wants better hands to fold. |
| Pot odds vs Implied odds | Pot odds count only chips in the pot now; implied odds add what you'll win later. |
| VPIP vs PFR | VPIP = how often you play; PFR = how often you raise. PFR can never exceed VPIP. |
| The 3-bet count | Blinds are bet 1, the open-raise is bet 2, so the re-raise is the 3-bet (not the first raise). |
Betting Actions
Everything you can physically do on your turn. If you're brand new, start with the 
order of betting.
| Term | Meaning |
|---|---|
| Check | Pass the action without betting — only possible when no bet has been made this round. |
| Bet | Be the first to put chips in the pot on a betting round. |
| Call | Match the current bet to stay in the hand. |
| Raise | Increase the current bet, forcing others to match more or fold. |
| Fold | Give up your hand and any claim to the pot. |
| All-in | Commit all your chips; you can only win the part of the pot you covered (see side pot). |
| Limp | Enter preflop by just calling the big blind instead of raising — usually a weak, passive play. |
| Open (open-raise) | Be the first player to enter the pot with a raise. |
| 3-bet | The re-raise after an open (the third bet, counting the blinds as the first). |
| 4-bet | A re-raise of a 3-bet. |
| C-bet | A "continuation bet" on the flop by the player who raised preflop. |
| Donk bet | Leading into the previous street's aggressor from out of position (once seen as a mistake, now a low-frequency tool). |
| Value bet | A bet with a strong hand hoping to get called by a worse one. |
| Bluff / Semi-bluff | A bluff bets a weak hand to fold out better; a semi-bluff does it with a draw that can still improve. |
| Check-raise | Check, then raise after an opponent bets — a strong, deceptive line (legal in modern rooms). |
| Min-raise | The smallest legal raise. |
| String bet | An illegal, undeclared reach-back for more chips; ruled a call, not a raise. |
| Jam / Shove | To move all-in. |
| Snap call | An instant, no-hesitation call. |
| Hero call | Calling with a weak hand because you've read the opponent as bluffing. |
Positions
Where you sit decides when you act — and acting last is a permanent edge. For how to actually use them, see position play.
| Term | Meaning |
|---|---|
| Button (BTN) | The dealer position; acts last postflop — the best seat at the table. |
| Small blind (SB) | Forced bet left of the button; acts first postflop (worst postflop seat). |
| Big blind (BB) | The larger of the two blinds; stakes are named by the blind sizes ($1/$2), and one big blind is the standard unit for measuring stacks. |
| UTG (under the gun) | First to act preflop — needs the tightest opening range. |
| Cutoff (CO) | Right of the button; second-best seat, great for stealing blinds. |
| Hijack (HJ) | Two seats right of the button; the start of late position. |
| Lojack (LJ) | Right of the hijack; late-middle position (labels shift with table size). |
| Early / Middle / Late | Groupings by how soon you act — early = tightest, late = widest and most profitable. |
| In / Out of position | You're in position if you act after your opponent, out of position if you act first. |
For the full seating map, see the 
table positions guide.
