Check-Raise Strategy in Texas Hold 'Em

Forcing Other Bets
In some cases, players bonuses will use the check-raise strategy to force other players to be more aggressive than they normally would. In other words, a player in an early position might check to force a player down the line to raise in a situation where he or she might not have done so. This is most effective when you are sure that such a player holds a weak hand.
Intimidation Strategy
Check-raise strategy can also simply be used to intimidate other players. This is why the move is not popular online poker with some players, as many find it unnecessarily aggressive and distracting. Still, it can prove to be effective in diminishing a player's confidence, which (in contrast to the forced bet strategy) can prompt them to play more passively, allowing you to raise a bet when it comes back to your turn.
Keep in mind that check-raise strategy is actually forbidden in some games poker, typically those in which the stakes are lower. Generally, however, it is permitted in mid-to high-stakes no limit Texas Hold 'Em. Still, to be truly effective, the strategy should be deployed only when absolutely necessary.
