There really are only two perspectives here to think about: Online and Live.
In both scenarios you can alter what someone perceives about your playing style at any moment, but by how much? and how important is it anyway?
Regarding online, there are two obvious opportunities for this. The chat box and/or showing your hand. To a lesser extent IMO, your actual image (picture) if your preferred software provides that option.
As for live play, there are a few things to consider, mainly:
- Personality, e.g. Extrovert, Introvert, ...
- Dress sense, e.g. Smart, Formal, Grunge, Goth, Wizard , Vampire, ...
- Social Elements, e.g. Drinking habits, Talking habits, ...
- Table Presence, e.g. Big/Little stature, Chip tricks, Chip stacking method, ...
- Positional, Stack-Size, Behavioural Considerations, ...
Some, of course, are more important than others. What I'd like to know is, not necessarily when or who to look tight or loose against (that's a strategy question/discussion of it's own) but,
What are the things you find the most effective at promoting a particular image of your playing style?,
and importantly,
Whether you get any use out of it or just ignore it all together?
What are your experiences. Thanks.
