#4 Being able to quickly identify villian types:

this sorta ties into #3. This wont, by any means pin down exactly how they play, but will give you a general guideline to bounce future information onto to see if your initial assessment holds up over time.

Bad passive – meaning they dont understand position, often limp into pots, calling stations, then give up easily when they flop nothing. When they raise they are definitely repping zee nutz.

Bad Aggressive – still are dicey on position, they still tend to be stationey, like to raise but are pushed around by 3betting In Position, they bet into 3 or more to act behind, they chase draws

Good Aggressive – understand position, will play a more TAG style but change up bet sizing somewhat to disguise their hands. Will understand spots [if they have the cards or not] where they can chip up with least resistance.

#5 i would say always having an awarness of stack sizes in relation to whose betting:

A] Are they 20bb or under – TIGHT RANGES, so lets say top 10% of hands. More than likely they are opening to ship at some point, usuallt preflop or on the flop [beware when betting INTO these players with anything that top 5% of hands]

B] Are they 30-50bb – A slightly wider range, lets call it top 20-25% of hands. They can more or less play their standard game and can 3bet, fire off barrels, float, squeeze [the shorties], but they are usually aware a bad beat can put them into fit or fold mode.

C] Are they 100bb+ – can afford to widen their ranges dramatically; to almost ATC (any two cards)[especially if the table is playing nitty (super tight). Often they will be attempting to pwn the table with a super LAG style and make peoples live hard.

#6 how does the table percieve your playing style:

which are you in #4 and why?

Because this will provide insight as to why people seem to be playing 'at' you a certain way.
