Before I make a twat of myself what are people interpreting his card checking as on the flop and then on the turn?
At the time, I genuinely thought he was checking his cards on the flop because he'd forgotten what he had. He raised first to go and it had taken a while to complete the betting round.
On the turn it seemed a classic do I have a club check.
This may be a little old school and possibly very wrong as I believe a lot of 'live' tells are pretty dodgy, but i thought,
First check he is probably checking for clubs
When he checks again on the turn he is checking with the little thought 'oh shit, ive got a flush running though his head'?
Open to being very wrong on this, but the fact you mentioned it obviously meant you thought it was significant.
Also open to the fact eveyone will be checking there cards a lot when we next share a table.
