The Baluga theorem relates to betting that takes place after the turn card and in particularly if you get raised at this point.
This theory states that if you are on a high pair after the turn card and your bet gets raised, you should be folding your hand because it takes more than a pair to raise in this position when playing No Limit Holdem.
When you are sitting on top pair with a strong kicker, it can be a very difficult fold to make, especially if there have been no clues in your opponent’s betting before this point. However, in the long run your hand will not be strong enough to match the bet and continue in the game.
Your biggest weakness in this situation is that you are out of position so you are always first to act in each betting round, thus allowing your opponent to take the initiative in the way that they bet. It is difficult to get information from them when they are last to act which makes it hard to put them on a range and determine if your high pair is good enough to beat them and anyone looking for poker tips should remember this.
If you were to call the raise on the turn, you have to consider how you would act after the river if your hand was not improved. It is almost a certainty that your opponent would make a continuation bet at this point and would test your resolve even further. If you would not be prepared to call a bet after the river then you should not be calling the turn card.
