Kinda Close

Let’s construct Big Blind defense range! (with Cameron Couch)

Pot odds

3.5x -> 33% -> alpha*0.955 = 33% -> alpha = 34%
3x -> 31% -> alpha = 32.4%
2.5x -> 27% -> alpha = 28.27%
2x -> 22% -> alpha = 23.03%

Let’s take rake into account. After you pay the rake, your winrate should be at least equal to pot odds. Then alpha*(1-rake) = pot odds. Alpha is the minimum equity we need.

If the pot is bigger than 44.4$, rake is only 2$. In SRP situation this doesn’t happen usually, so I’ll take this out of consideration.

2. Vs villain RFI (80% equity realization - passive or weak opponents)

Let’s give 2.5% more to suited connectors.
Let’s give 3% less non suited dominated hands.

10% - A9s(32.2%), A8s(31.7%) -> below A9s bluff candidate
KQo(32.1%) -> bluff candidate
QJs(29.8%), T9s(28.1%) -> below KQs it’s fold or 3b

15% - A8s(35%), A7s(34.37%) -> vs aggression we can get away from hitting A together
67s(29.4%), 78s(30.88%), 89s(32.01%), T9s(33.25%) -> good 3b bluff candidate
KTs(34.15%), K9s(32.34%) -> K9s bluff candidate
KQo(32.94%), KJo(32.1%), QJo(30.8%), JTo(30.2%) -> below KQo is fold vs UTG, even KQ has domination issue so 3 bet would be better
QTs(32.88%), JTs(32.7%), J9s(31.4%)-> below JTs, 3b bluff

20% - A4s(35.34%), A2(34.2%)
A7o(34.2%) -> but I would call suited connector rather.
67s(30.2%), 78s(31.05%), 89s(31.7%), T9s(32.34%) -> below 89s 3b bluff
K8s(32.75%) -> K7s bluff candidate
KJo(33.54%), KTo(31.83%), QJo(31.38%), QTo(31.4%), JTo(30.89%) -> below KJo it’s fold
Q9s(32.5%), J9s(32.01%), T8s(31.4%) -> J9s, T8s as bluff

Q: Is K8s better than 89s?

25% - 67s(31.78%), 78s(32.41%), 89s(33.43%) -> below 78s 3b bluff
K6s(34.35%), K5s(33.83%), K4s(33.28%), K3s(32.76%), K2s(32.29%) ->
Q8s(33.17%), Q7s(31.95%)
J9s(33.36%), J8s(32.07%)
KTo(35.44%), K9o(33.14%), QTo(32.53%)
78s(32.46%), 67s(31.59%)
T9o(31.61%) -> T9o is fold

50% - Q2s(33.36%)
J5s(32.73%)
T7s(33.2%), T6s(32.14%)
97s(33.8%), 68s(32.51%)
67s(33%), 56s(32.39%)
K7o(35.03%) -> real equity will be lower than this.
98o(31.15%)

60% - J8o(35.54%), J7o(33.88%)
J2s(33.09%)
T5s(32.65%), T4s(32.36%)
96s(33.23%)
75s(32.61%)
45s(32.18%)

All the ranges are on the assumption opening size is 3bb.

New learning:

suited connectors/gappers don't have SDV, so it's less inclined to call rather than 3b
suited K and Q even J has higher EV than I thought
off suited connectors are weaker than I thought

Limitation:

I've done this only with Equilab so it's not exact computed number nor range. If you have better softwares, please point out my errors.

About me

Hey I play PS zoom 16nl/25nl. Since my skills are not there, I want to share my naked thoughts with you guys. I'll post defensing range vs strong opponents tomorrow.

How can we compute this or that hand is too thin to value SQ or not?

https://www.weaktight.com/h/5814d94ad390439d1a8b478d

I believe this is value raise, but I hope they rather fold. flop should be check by the way.

MP is 20/15 in 74 hands. I thought he holding QQ doesn't want to see the flop with 4 ppl so I pushed. Can I still hero fold?

vs regish unknown.

Hey guys. I am a recreational player and new to this game. So I am completely open to share my thoughts.
If anyone wants to share thoughts, review HH, sweat session, chat me in skype
