I actually think online poker's helped me with tells
, but mainly just the getting better part. Instead of going into the "OMG I'M GONNA BLUFFF" mode I think "standard cbet with dry board and overs". I'm pretty good at concealing what I'm thinking but whenever I'm facing an all-in decision I'll think aloud, some people thought it was funny when normally I'm just sitting there making all my moves pretty quietly and calculated, and all of a sudden all-in and I'll be like "****, you kidding me? What the hell does that here?".
But yeah, I started out playing live with friends, and online has definitely gotten me better in terms of tells, simply because I've played so many hands and basically am pretty good with what the default play is and what kinds of ranges to put opponents on so I make sure every action I make is deliberate. Only tough thing has been putting in chips, I've had to work on making sure I put them in the same way because even if I don't think the actions are based on hand strength, it's just generally too tough to keep a tab on it.
