Ms Vujanic says you can pick up little cues from these things and adjust your own behaviour accordingly. Is the person sitting across from you breathing heavier? Are they fidgeting? 'You need to be really in tune with what you're doing and your own body language, but also very observant with other people.' 'At a poker table you should be watching every single thing,' says Ms Vujanic. 'When you're playing for a lot of money and you've got all your chips in on a complete bluff, it's so important to not give away anything to your opponent.' Be observant Reducing anxiety - or even just seeming less anxious - is crucial in high-stakes situations, Ms Glazier says. If you take long and deep breaths instead, there's a good chance you can calm yourself down. When you're anxious, your breaths are generally quick and shallow. It's well established that stress affects your breathing patterns. If you're struggling for something else to focus on, your breath is a great place to start.

'It's a way that I can take myself away from the situation.' I'll stare at a spot and count to 100 if I need to.

'It's not counting cards - it's just counting. 'I count a lot at the table,' Ms Glazier says. The idea that these poses can tangibly decrease the stress levels in your body has been repeatedly disputed, but multiple studies have confirmed that people report feeling more powerful after doing it. The idea of 'power posing' was popularised by social psychologist Ann Cuddy in 2012: she reported that adopting a confident pose (think: Wonder Woman) for a few minutes before a big event could literally make you more confident. She says she always makes an effort to sit up straight and tall at the poker table: 'When you take up space … it becomes easier to manage your emotions and feel like you're in control of the situation.' 'One of the best things you can do is focus on your posture,' Ms Vujanic told ABC Radio Perth. Want to work on your own poker face? Ms Glazier and fellow poker pro Tanja Vujanic have a few tips.
