Defending your chips is an important aspect of poker, especially when you are in a position of power as a big stack bully at the table. There are a few strategies you can use to improve your chip defense.
One strategy is to be more selective with the hands you play. Waiting for a very strong hand like AK or a pocket pair like 88 and higher is one way to do this. Playing only strong hands will reduce the chances of losing a big pot to an inferior hand. However, this strategy can also make you predictable and easy to play against.
Another strategy is to use your big stack to your advantage by applying pressure to your opponents. You can do this by raising more often, especially in position, and by making larger bets and raises. This will make it harder for your opponents to call or raise with weaker hands, and can force them to fold more often.
Another strategy is to play a more balanced range of hands, including some weaker hands that you can use to bluff your opponents into giving up their hand. This can add an element of unpredictability to your game, making it harder for your opponents to read your hand.
Regarding suited or offsuit hands such as 5,7 or 10,9, it's generally considered that these hands are not strong enough to call or raise pre-flop, unless you're in a position to do so. These hands have a low chance of winning, and will often result in a loss of chips.
It's also important to consider the current dynamics of the table, position, the players at the table, their tendencies and the stack size, etc. It's all about finding the right balance between playing tight and aggressive, and using your position and stack size to your advantage.
In summary, defending your chips in poker requires a mix of patience and aggression. Being selective with the hands you play, applying pressure with your big stack, and playing a balanced range of hands can all help you to defend your chips more effectively.
