Stats are my friend both online and live - but observationally, i have come across some very skilled players who can act so well in a live situation and will use any angle to disguise their play, conversation is an obvious one with information sharing but also erratic bet sizing, lack of observation of players turn, over betting, calling - i always focus on showdown cards at the end but its the journey that player makes to get there that fascinates me.
Recently, online and CC games, i have taken an interest to a few players play and in particular the need to want to show a hand when they
bluff, this makes me smile and its also recognised by me as a very good weapon and tool if played well and disguised well.
I prefer to limit all information and in live play i hardly say a word but will join in with a joke at the table and i still occasionally have table service with a glass of wine or a hot drink depending on how i feel. Consistency is the key for me.
I have a certain approach when observing and make notes about players and i revisit this regularly, ive noticed recently that the same players rail and observe our league games and stay for the latter stages of a FR, i think this is a good strategy as we are all in one way or another looking for bits of information and sometimes we come across an opponent that gives very little away - study, revisit and be prepared to learn always i say.
Body language live is huge, pace of play another - but dont be fooled by online players who always run the clock down or take their time - let them, just like - let the bluffers bluff- its their perogative, just sit, silently and wait to strike....
