Hi,
please forgive and correct any blatant errors, miscalculations or oversights in logic or methodology. maths has never been my strongest asset but i'm determined to give it a go.
I have been reading Alex Fitzgerald's chapter on hand analysis in Jonathan little's "excelling at no limit" and this is where the method I am attempting to employ (for the first time) is coming from.
I have picked a spot in a low stakes MTT that I felt at the time I might have been able to attempt a 3bet bluff. I chickened out at the time but marked it in order to run some maths after to determine if it could be a potentially profitable spot to 3bet bluff with ATC
I think that perhaps one of the most daunting part of calculations such as these for me at the moment is trying to assign a hand range to a player that we have little information on. so criticism on this aspect will be much appreciated also.
method:
step 1: determine how often this bluff must work in order to show an immediate profit
In this hand I am in BB with roughly 50BB. Action folds to the btn with 100BB+
blinds 250/500/65. Btn raises 3x (1500). SB folds. I consider a 3bet bluff to 5000.
So, if my maths is correct. Then this bluff needs to work 61.3% of the time in order to show an immediate profit:
4500/(4500+2835)
=4500/7335
=0.613
step 2:Now to assign villains range.
Btn is unknown but is in good shape with 3.5x the average stack size, and 100BB+. I assume therefore that his range here should be wide, I would assume probably wider than that which I have assigned of 32% (22+,A2o+,A2s+,K7s+,K9o+,Q8s+,QTo+,J9s+,JTo,T9s,98 s,87s,76s,65s,54s)
step3:calculate what range villain must defend with in order to make us not 3bet with ATC:
villain opens 32%
villain must defend 61% of 32% = (0.61)(0.32) = 0.195 or 19.5%
therefore villain must defend 19.5% of hands, which includes 33+, all suited aces, A5o, KTs.
conclusion: This could potentially be a profitable spot to attempt a 3bet bluff as villain is unlikely to be defending smaller pairs and mediocre aces.
Further aspects that I should consider?
The hand I have is complete junk. Should I attempt this with, at least, a hand that has some potential equity if I am flatted, i.e a suited hand?
I have very little information on villain. would I be better waiting to get a better feel for how villain plays?
Thanks in advance for commentary and criticism.
