In my eyes, the worst thing beginners do when playing poker is playing every hand they get. They play if they get K7, they play with Q5 or A6, they even play the 72 and hopes that the flop will bring them trips or even a full house. Nonsense! You will never ever become a winning player by playing such hands. Do you know why poker tournaments take so long? Do you know that poker pros only play one hand of 10, and that is only because they are on the big or small blind and have to play. Every poker pro is waiting for a monster hand to play with or they play with suited connectors or expects for flush, but believe me, they never play K7 or Q5.

Stop calling with hands like that. If you play such hands in the dealers position or even the blinds then you have a chance to limp in and maybe even get lucky, but fold them in any other position and especially in early.

Folding rubbish hands will bring you millions. Believe me!

The 10 Worst Mistakes in Poker

To make online poker faster, online poker rooms added many features to the poker room lobby. There is an auto fold, raise, check, call or
check/fold button added to most online poker rooms.

I agree that most of these buttons are useful and improves game, but
check/fold button is a bit different. This button comes into play when
you are on the big blind and if you use this button you can easily give
away your card. Why? Well, your opponents will see that you are using
check/fold button and if they want to steal your blind or want to get
rid off one caller they will simply raise. And if it is even the smallest raise, your hand will be auto-folded. Nobody wants to you to see the flop as it may be useful even for the worthless hand.

I agree this is not such a big problem for low stakes poker, but if you
play higher stakes poker this might cost a lot. It's a small tip for you to move further.
