We call blind robbing the act of raising the preflop bet with the object of taking the blinds and antes, regardless of the strength of our hand.
The ideal situation is to do it from the end positions, when all our rivals have abandoned and, especially, when the blind are playing a very closed range of hands and rarely respond to our aggression. Once we have confirmed that we are facing this type of players in blind, we have the advantage of being able to do it with a great variety of hands. Even with some junk hands, since these players will only respond when they have very strong hands. When we find resistance, our movement will be very simple: abandon the hand. It is very likely that we are facing a very strong hand.
On the bubble, we must remember that, in this case, the weakness we seek is above all in passivity and in the closed range. In fact, before players able to pay several bets with marginal hands, which implies equally weakness, our game must always be by value, exploiting their mistakes in the game. In these situations we must ensure that the size of the stacks left to speak, if we are not in final positions, and blind players will allow us to carry out our plan.
