Dunna asked me a few days back to describe the biggest leaks people have from the blinds. I have been doing a lot of work on it for the last week so here is a little synopsis for the SB of what I have so far.
My standard in the SB used to be 3bet QQ+, AK and get it in(sometimes JJ too). 3bet bluff people with a fold to 3bet above 55% with Axs and Kxs. Then I would cold call anything I felt I could make a profit with.
Against a competent reg it is extremely hard to make any money cold calling from the SB for a few reasons.
-The four things we use to our advantage to win playing poker is skill, position, initiative and card strength. When we cold all from the blinds we are OOP, don’t have the initiative and have a capped range. Against a competent reg we will never be able to make up from all of these 3 disadvantages just with skill.
- We can’t cold call OOP with a wide range so when we do cold call our range is pretty transparent and a good player can use this to their advantage quite easily. For example if the board comes down 234 we rarely have any sets/straight draws 2p while the opener can have them all.
-We will get squeezed a lot and denied our equity when in the SB.
So as a standard I think 3betting a linear range in the SB is best. By 3betting we take the initiative back and don’t split our range into transparent sub ranges. Obviously we deviate from 3betting a linear range a lot of the time since people have a lot of leaks we want to exploit.
For example say we are facing a 2.5x open from the CO and we in the SB 3bet a linear 12% range as a standard. Villain is a 22/20 with 85% FT3B over 500 hands. Here there is no value in 3betting anything so I’d flat the top 7% or so of hands and 3bet him a lot with blockers. By 3betting a linear range here we are actually letting him exploit us somewhat because we are wasting equity.
So I was thinking, how much should we be 3betting as a standard vs an opponent who opens on the button when we are in the SB. When you min raise the button, to break even you need your opponents to fold 2bb/(2bb+0.5bb+1bb) = 57% of the time (bet/bet+pot). So that means each the SB and the BB should fold the sqrt(57%) = 75% of the time which implies we must defend 25% of the time each. Now in the SB we don’t need to defend quite that much because the BB is still left to act and the BB is getting better pot odds. So vs a min raise on the button we should be defending roughly around 20% of the time when in the SB. That means I’m 3betting the top 20% vs a standard Tag which will look something like <AA-77,AKo-A9o,KQo-KTo,QJo,AKs-A2s,KQs-K5s,QJs-Q9s,JTs-J9s,T9s,98s,87s>
Using the same method we can work out that we need to defend 21% of the time vs a 2.5x raise and 19% of the time vs a 3x raise which we should reduce to ~17% for 2.5x raise and ~14% vs a 3x raise.
Now we can do this for all positions. When we are facing a CO 2.5x he needs everyone to fold 62% of the time. That mean we in the SB should fold the cubed root of 62% which 85% of the time .ie we need to defend 15% of the time. Due to the button being IP on the CO he is going to defend slightly more than us so we need to defend roughly around ~12% of the time. Vs a CO 3x open we need to defend ~10% of the time.
Do this calculation for every position and here is what you get.
Vs BU 2x – defend 25% ==> 20%
Vs BU 2.5x – defend 21% ==> 17%
Vs BU 3x – defend 19% ==> 14%
Vs CO 2.5x – defend 15% ==>12%
Vs CO 3x – defend 13%==>10%
Vs MP 3x – defend 10% ==>8%
Vs UTG 3x – defend 8% ==>5%
3betting 20% of the time vs a button minraise is quite a lot. Your will seriously get owned if you do not widen your 5bet range(assuming we don't have a call 4bet OOP range) to something a lot wider than QQ+AK. Still thinking about how wide we should go so il get back to you on that. I'm probably not going to be 3betting quite as wide as 20%. Il start about 16% and work my way up when i'm confident it will be more profitable. These numbers are just starting points. No need to stick to them wholeheartedly. If you don't feel comfortable 3betting 20%, don't. I don't so I won't.
Now this assumes that there is a standard TAGs all around your table. If the BB is a nit and Button min raises you will have to defend more than 20%. The opposite also applied. If BB is a manic you should defend less. This is only of course if the opener is a receptive reg who understands opening ranges and adjusting to tables.
It also assumes that you’re facing a standard Tag. If you’re playing vs a nits open tighten up the range. If against a Lag, loosen up.
So il leave actually choosing the standard 3betting ranges up to you. It’s pretty simple. Basically choose the top X% of hands with preference towards big cards, Axs and Kxs.
So examples of when I wouldn't 3bet a linear range.
-Villain has a high FT3B. I explained this earlier.
-Villain has an exploitable postflop tendency. Ie folding too much to check raises, cbetting too little/ too much, barrelling too little too much ect ect. Here we should cold call OOP to exploit his postflop mistake. How much should we flat? That depends how big of a mistake he makes. Someone who only cbets with TP otherwise checks behind and folds to a bet we can play something like 70%+ of our range. Someone who doesn’t barrel often enough we can probably flat like ~10%-15% of hands(pulling numbers out of my arse here).
-Someone left to act is a spew monkey with a high squeeze%. Here I’d flat the premiums and back raise with the intention of getting it in and 3bet the rest of the range.
What I did was work out all the ranges and saved them into flopzilla so I can reference them in game.
Going to work a bit on my BB game some more and if I find anything interesting il also post it. Pretty sure my logic is sound here and there are no errors. Anyone spots any let me know. Cheers.
