Poker Tells that Say "I Have a Good Hand!"
- Acting Uninterested in a Hand While Still in It
This is usually a sign of a strong hand. The player is pretending that he’s not excited about his cards – but he is.
- Shaking Hands
During a hand, if you notice a player’s hands are shaking as she places her bet, she probably has gotten a really, really good hand. Perhaps the nuts.
- Rapid Breathing
Some players can control the shakes, but it's harder to control the automatic heart-racing that comes when you see pocket aces or hit the flop really hard. If you can see a player's chest visibly rising and falling, they have an excellent hand
- Sighing and Shrugging
If a player makes a show of sighing or shrugging, and says things like “Oh, I guess I’ll call,” or even “Why am I calling?” he probably is overacting and is trying to hide a big hand.
- Glancing at Chips After Looking at Hole Cards
When a player looks down and sees strong hole or pocket cards, she may glance over at her chips to see just how much she can bet.
Poker Tells that Say "I Have a Weak Hand!"
- Staring Down Other Players
If an opponent is staring you down, he’s trying to represent strength. Usually though, he has a weak hand – he might have something, but it’s something that can be beaten or drawn out on.
- Holding Breath
Often, inexperienced players will hold their breath if they are bluffing.
Poker Tells that Say "I Have a Drawing Hand."
- Checking Hole Cards After a Flop
If the flop shows the possibility of giving someone a flush or straight draw, watch for people re-checking their hole cards. They’re checking to see if they have a piece of it – whether that black Ace was a spade or a club. The player doesn’t have the flush or straight at that point, because if they did, they wouldn’t have to check, but she is seeing if she has a draw to it.
- Taking a Long Time Before Calling a Bet
If a player looks into the pot and seems to be doing some calculating in his head, he probably is. He’s most likely figuring out the pot odds to see if it’s worth it to try and catch the cards he needs to complete his drawing hand.
A final note: more experienced players may give off false tells, so the first thing to read about other players is if they’re novices or pros.
I know this is not about internet tells but I just found the last paragraph interesting. Whenever I go to a casino where the players don't know me, the first thing I'll do at a table is start listening to the players talk.
There are usually 2-3 players on a 1-2 table that at least "think" they are pros (most of them wannabe's). Usually the ones that are judging other people's plays, over aggressive, always make sure they look at their own hole cards when it's their turn, etc. I'll act like I rarely play poker and I may purposely do some amateurish bets - like min raising, etc. Eventually I'll end up in a big pot with one of these players and that's when the acting begins...
For example, if I totally missed my hand and the board is paired - and I put my opponent on a mediocre hand, like two pair, etc - I'll intentionaly make my hand shake as I'm putting the chips out to
bluff - works every time. lol
Another reverse tell I'll use is looking completely not interested in the hand when making a big bluff - be careful trying to do that one, it only works against experienced players that have read the books.
When I have the absolute nuts against these players I'll sit up very firm in my chair and lean towards the table and make an overaggressive bet - that works like a charm against good players. I can't count how many snap calls I've gotten when I do it right against the right players.
The looks on the players faces afterwards is absolutely priceless.
