Bluff Catching Theory

1) DO WE BEAT SOME OF THEIR VALUE RANGE?
-player dependent-> look at their actions preflop to postflop
-"how thin do they go for value?"
-"are they making random bets?"
-IF CLOSE -> MAKE THE HERO CALL

2) PLAYER TYPES
vs MANIACS/AGGROS/FISH
-lots of bad aggression and random bets
-look for tilts + egos
-we assign them high ratio of bluffs and value hands
CALL THEM DOWN LIGHTER

vs LOOSE PASSIVE
-usually just betting their hand and not their range
-very rarely bluffing multistreet/ big pots
-GIVE THEM CREDIT BUT WE CAN SOMETIMES BEAT SOME OF THEIR VALUE HANDS

vs TIGHT PASSIVE
-always have what they're repping
HAVE A VALUE HEAVY RANGE
NO NEED TO BLUFF CATCH AT ALL

vs REGS/SEMI-REGS
-very balanced and not many random holdings
MORE SKEWED TO VALUE HEAVY RANGE

3) ABILITY TO GET TO SHOWDOWN
-if we think we won't get to showdown -> we can fold right away when facing flop/turn bets
-IP and small sizings we can float much wider
-depends on players types + different board textures

WET BOARDS
-harder to get to showdown
-tighter betting range on flop -> they have many strong hands + draws
HERE WE CAN FOLD OUR MEDIUM VALUE HANDS RIGHT AWAY
eg. KT on [JT8]-> lots of bad turn cards so we fold right away vs aggression

DRY BOARD
-easier to get to showdown
-wider betting range on flop + not many draws and strong hands possible
-harder for opponent to improve on many turns so we can float wider
eg. 99 on [TT5] 3way -> they can be betting a 5 or weaker pocket pairs so we can float
eg. KJ on [K64] very dry therefore easier to get to showdown

vs WEAKER/PASSIVE PLAYERS
-easier to get to showdown -> often bluffing once with wide range and give up
-here we can float wider

vs MANIACS/AGGROS
-harder to get to showdown
-wider range -> we float wider but prepare to call down more often
-if runout doesnt improve their range we may have to call down

vs REGS
-can expect reasonable barreling
-think about their actions + most obvious bluffs + draws and value hands
eg. they raised UTG we defend BB, they will cbet 100% of their range on the flop

vs TIGHT PASSIVE
-usually hard to get to showdown
-preflop and cbetting range is very tight and value heavy

4) RANGE COMPOSITION
-what player type? 
-what position?
-what are the actions preflop and postflop?
-narrow down their range on all streets

HOW WIDE IS THEIR VALUE RANGE ON TURN/RIVER?
-very wide? we do not need to bluff catch at all
eg. [JTQ][4][6] vs triple barrel -> they have very strong range therefore no point bluff catching
-very narrow? we can bluff catch more often
eg. [TT3][2][3] vs triple barrel
-> here opponent is repping either a T or nothing -> we can hero call more often

5) BOARD TEXTURE/RUNOUTS
-how wide their bluffing range is on turns and rivers?
-> if many draws improved, their value/bluff ratio is high therefore we can not bluff catch often
eg. [3JT][4][A]
-KQ and AJ improved therefore we don't want to call down light in this spot
eg. [8T4][Q] flush complete vs double barrel
-he could have a flush. J9 or QT so we cannot call down light

IF MANY DRAWS BRICKED...
their bluffing ratio may be high therefore we can bluffcatch more
eg. [9Q3][4] 2 FD
->his flop cbet has gutshots, BDFD and FD therefore we still want to call with the same frequencies as the flop
eg. [T8K][5][3] - FD missed vs aggro barreler
-> the straight draw missed, FD missed therefore we can bluffcatch here

6) TABLE FORMATION
-what position is he raising from?
-how many players are in the pot?

IF BETTOR IS IP-> HE HAS MORE BLUFF IN HIS RANGE
IF BETTOR IS OOP -> HE HAS LESS BLUFFS

SAME FOR RAISES AND CHECK/RAISES
-if he check/raises with many players behind-> very strong range
-if he check/raises HU IP-> could have some bluffs

7) OPPONENTS' LINE

UNDERBLUFFED LINES:
a) Multistreet aggresion
eg. OOP triple barrel
eg. 3bet, bet, bet IP
b) River raises
-> almost always nutted -> make massive hero folds often
c) Turn check/raise non all-in with money behind

8) OUR PERCEIVED RANGE
-is opponent good enough to factor in our perceived range?

WHEN OUR PERCEIVED RANGE IS STRONG = BLUFF CATCH LESS
-players will bluff us less + we have stronger hands to call down in this spot
eg. [A56][6][T] - here we have tons of Ax and they have little fold equity-> they will not bluff this run out
-> here we can easily lay down our pocket pairs and weak Ax
eg. IP on [JT3][6][9] flush completing river
-> after we called twice we can have KQ and flushes that improved therefore they will not be bluffing in this spot very wide

WHEN PLAYING VS CALLING STATION -> HE EXPECTS YOU TO CALL WIDE
-we can make hero folds more often

WHEN OUR PERCEIVED RANGE IS WEAK/CAPPED = WE HERO CALL MORE
-players will look to attack our weak range
eg. 98 OOP on [924][3][Q] vs aggro barreler
-> if aggro player bets big on an overcard-> they are usually bluffing

IF YOUR RANGE IS CAPPED AND YOU'RE PLAYING VS AN AGGRO PLAYER, YOU HAVE TO MAKE SOME HERO CALLS IN THE RIGHT SPOTS

9) SIZINGS
BIGGER SIZING = STRENGTH IN GENERAL
OVERBETS = VALUE -> make hero folds
SMALL BETS OFTEN THIN VALUE -> RANDOM BETS (3rd, 4th pair)
