Sometimes it's not what you have but what your opponent has and if you know dont they dont have much and wont call a certain amount then you should bet it.
I once called a big 5 bet preflop with 55 . Half the table went all in preflop. The rest of the table went all in after the turn. I hit a 5 on the flop and the other 5 for quads on the turn. I was chip leader pre hand so I KO all the players on the table. I started with $40 dollars and cashed out a bit over $1,300.
One of my most bizarre hand's I have won was on-line, I was folding hand after hand in a game and got talking to another player, who had the same problem, he Said "He wished he could get a playable hand" and I replied "Yes, same here, I am sick of being dealt 7/2 every other hand".
Just as I sent the message I was dealt 7/2 of Clubs on the BB and even posted the message "Oh look 7/2 AGAIN!"
There were only 2 other players who limped into the hand so I checked, Flop came 3 Club cards and knowing I could be beaten by a simple 8 high flush I checked, one of the limper's bet half pot, the other called and after some thought I came along for the ride.
Turn card gave us a Diamond, so I checked again, first limper bet again half pot 2nd called so I called again not knowing what anyone else had. River dropped a Heart card which could have given someone a straight, but I thought if someone held a bigger flush I was still in trouble.
I checked the River and the 1st limper bet out again half pot 2nd now folded, so after some deliberation I sent a message to the other player,"You either have me beat or not" I shoved all-in with my 7/2 Flush and he called with a straight.
The player I had been talking to before the hand sent (LOL and NH) messages and I said "I told him I only had 7/2.
This is why I love playing Poker, for the fun of the game,
i dont remember a particular hand but when i am in position i sometimes call with junk and you can hit really big with it . for example when i know someone has AA-QQ and i am on the button i call with lets say 7-4o and when i hit big i get a lot if not all of his money or stack
I had someone limp AA in EP in a tournament when I was in the BB with 63o, their limping triggered many more limpers and I think 3/4 of the table must have limped in by the time I checked.
The flop was 333 and I don't remember the exact details of the rest of the hand, but I do remember that I won a massive pot because two other players also had pocket pairs and there were multiple all-ins by the time we went to a showdown.
That's the risk you take when you limp with AA, don't get mad if somebody crushes them because you let them see a cheap flop.
