I confess that yes, I have played higher limits than allowed by my bank, usually these situations occurred post bad, to try to recover a lost value in the course of the day quickly, playing a high buyin cash, spin and go, or expensive tournaments. And I inform you with full certainty and experience; IT'S NOT A GOOD IDEA. Be cool as a poker player has to be, accept the losses, and most importantly, in the bad phase, minimize your losses, and in the good stages, maximize the gains, enjoy making the biggest profit of the best hand, playing convincingly and without haste.
