Since I'm going back to the basics, I might as well post some material here.
It's mainly for my own studying benefit, but if someone is interested in this kind of stuff it's cool.
It's not well organized and could look like mostly rambling, but that's the nature of my notes lol, what can I do.
1. SRP BTNvsBB (Paired Board)
A
paired board will occur about ~17% of the time. Usually the most common misplay on this kind of texture for both players it too playing it
too passively compared to optimal frequencies.
In general IP will use a
small bet size (around 25% of the pot), against with BB will have to
raise aggressively to prevent BTN from cheaply realizing its equity.
Given the range interactions, the higher the board pair, the more we'll bet our range as BTN; this is beacuse BB will be left with a lot of undercards to the pair, which will have a tough time calling any bet.
On boards where BTN has more/better trips than BB in his range, it should bet its
entire range.
1. BTNvsBB Flop CBet (4.5BB Pot)
On this kind of texture BTN is betting basically
all of his range for a 25% pot sizing, the amount of checks or bigger sizing is almost negligible.
BTN obviously has every suited K and a lot of off-suit ones, while BB will 3bet some Kx preflop, resulting in not having as much of those in its flatting range.
2. BTNvsBB Flop CBet (4.5BB Pot)
Same goes for 99x.
3. BTNvsBB Flop CBet (4.5BB Pot)
On lower pair boards BTN should
cbet less often, since BB will have more trips that can x/r the flop cbet and put more pressure on BTN 2Ps and high-kicker portion of his cbetting range.
As you can see BTN should still cbet its trips at an
high frequency, checking back some of weaker ones in order to prevent BB to exploit a capped checking range with large
turn probes.
About overpairs, BTN will prefer to
bet the lower ones at an higher frequency, checking more often the higher ones.
This is beacuse weaker overpairs are
less likely to block BB high cards floating range, while stronger overpairs will need
less protection and can defend more easily vs a probe or eventually bet themselves OTT if checked to.
4. BBvsBTN Facing Flop CBet (4.5BB Pot)
5. BBvsBTN Facing Flop CBet (4.5BB Pot)
Facing a cbet as BB, we need to notice that since BTN's weaker portion of its betting range would still have some EV when checking back the flop, BB is allowed to
overfold its naked undercards to the pair, despite the small cbet sizing.
To compensate for the overfolding, BB will mostly
aggressively raise with its continuing range, sometimes resulting in a raising range larger than the calling one.
Given how merged BB range will be, the raising size should be kind of small.
To raise, BB will mostly use its trips, some of its 2Ps and combos with multiple BDs.
6. BTNvsBB Facing Flop XR (9BB Pot)
As BTN, facing a flop x/r we'll need to continue with a
large portion of our range to keep BB's bluffing (I hate to use this word before the river but w/ever) range indifferent.
The vast majority of BTN's continuing range will be played as a
call, including trips.
This allows BTN to use its positional advantage going to the turn, where many cards can obviously change the board texture, opening up to lots of draws and pairs both players' ranges.
You can see that BTN will float BB's x/r with every value combo as well as all of its BDs.
7. BBvsBTN Flop XX Turn Probe (4.5BB Pot)
Since BTN will cbet its trips at an
high frequency, OTT after a flop XX BB will need to extract as much value as possible with its trips vs a
capped range.
100x deep, in order to
GII by the river, BB wil need to overbet (even 200%-300% pot), when probing turn.
On turn overcards BB will use a
polarized betting strategy vs the now advantaged BTN's range.
8. BBvsBTN Flop XX Turn Probe (4.5BB Pot)
On lower turn cards, which favor BB's range, it can use instead a more merged betting strategy.
9. BTNvsBB Delayed CBet (4.5BB Pot)
BTN, after a flop XX, will choose its
delayed cbets depending on the turn card.
On
undercards to the flop kicker, it can bet for thin value with high cards combos such as AQ/AK for around 50% pot.
Unless the turn card is really bad for BTN's checking range, it'll always bet its remaining trips and overpairs, which means that BTN double check range will consist of the weaker high-kicker hands and the weaker 2Ps.
10. BBvsBTN Facing Turn DCBet (6,75BB Pot)
As BB, facing a
delayed cbet, same way it happened for the flop cbets, since a big part of BTN's "bluffs" (again, wrong term but you w/ever) will still have some SDV BB can overfold vs the delayed cbet those combos that lose to some parts of BTN's bluffing range.
Against a standard turn delayed cbet sizing (around 50% to 100% pot) BB will continue with all of his trips, most 2Ps combos and some of its best high kicker hands.
The trips BB didn't probe turn with will be used as a x/r at some frequency, the rest of them will be called looking for a river x/r or a call depending on BTN's river sizing.
11. BTNvsBB Turn DB (6,75BB Pot)
BTN double
barrell strategy wil also obviously depend on which is the turn card. After BB's flop x/c, BB range will usually be stronger than BTN since it was mostly supposed to overfold against BTN high frequency small bet.
As a result, BTN should
check back at a decent frequency.
So BTN turn double barrels will use a
polar range, resulting in a larger sizing (around 50-100% pot).
It will double barrell the majority of its trips, checking back the weaker ones looking for a river call/raise depending on the size of an eventual BB's river probe.
If turn is a brick (undercard to the board that doesn't complete any draw), the 2nd barrell will usually be on the
larger side.
Overpairs will often get checked behind looking for a river raise on many runouts, while weaker PPs and 2Ps with an high kicker will be bet at an high frequency and checked back on most rivers.
12. BTNvsBB Turn DB (6,75BB Pot)
Turn overcards will usually help BTN's range the most. On the lower overcards compared to the board pair BTN will bet a wider range using a
smaller size (50% pot) in order to get value from the new TP combos in its range, especially if the turn overcard brings a FD or a SD.
The strongest top 2Ps can check back looking for a
river raise vs a probe on most runouts. Some weaker 2Ps can check and just
call OTR.
Turned draws should be bet at an
high frequency, but combos with high SDV works better as a check (as for example A-high draws).
13. BTNvsBB Turn DB (6,75BB Pot)
On dry paired boards, BB will float flop cbets with many Ax combos, which means that an Ace OTT will also
help BB's range.
On these turn BTN should revert to a more
polar double barrell strategy.
14. BTNvsBB Turn DB (6,75BB Pot)
At last, on second board pairs BTN will bet a
merged range composed of mostly top boats and vulnerable 2Ps combos, checking the bottom boats, high-kicker hands and the best overpairs for SDV.
When turn boards a trips the proportion of quads in each range is halved, therefore the showdown value of A-high hands is much higher.
BTN should check in such a case its best value hands that blocks the Ax in villain's range, looking for a river raise vs a probe on most runouts.
