When you play against a preflop raiser during a play poker online game, there are two things to consider. Chip stack will dictate how the game will be played since most small stacks will be forced to bet the best they can after a large raiser while stack leaders will fold after missing the flop.
Another important thing to consider while playing poker online game is having the right position in the table.
Playing Early Position
If you are in a big or small blind position you have the opportunity to put some pressure on the best online poker raiser. You can call a small raise in case you have on hand suited cards, small pockets, or connectors. This will give the other poker players the impression that you got something on the flop. In case someone goes over the top, then decide if you have to fold what you have.
There might also be situations where your opponents will have monsters at hand when ace or face cards come out of the flop. Poker game online can be check and fold.
Game to Play in the Late Position
When you have a late position you can call raises to pairs of cards above 9s; A paired with a 10, J, Q, K; or a K with a J or Q. Watch out for flops like 4,5, J or a 6,7, Q if you have a KJ or KQ since most preflop raisers might be playing AJ or AQ. If the preflop raiser checks, then you can make a move and bet on the flop.
You and your opponent can also end up missing your hands. When you have a rainbow on the board and the opponent checks, then bet your way to his mind. Playing over the top is also another option. This strategy might not work for small stacks which may decide to go all in.
