Hello everyone.

In this thread I want to share how I build my ranges against flop continuation bet BB vs BTN, I'm going to simulate differents situations against differents opponents tendencies, my main goal is to open a discussion on how is the optimal way to adapt to the preflop aggressor strategy and what would be the best strategy to play on the turn take in to account the profile of each player. Let's start with the Villains stats:

Villain N°1 uses a very aggressive style, his VPIP 30 / PFR 25 / Cbet 70 / WWSF 51 and is likely to make larger bet sizes >66% pot.

I'm going to use two types of boards, where ones the nut advantage is for the preflop raiser and the other one is favorable to us, the boards types are: A♠ K♦ 5♠ & 9♠ 7♣ 5♦

Let's start with the scenario where villain N°1 has the positional and nut advantage on the board AK5. My first adjustment to this type of player is to tighten up my BB defense range, because I'm going to see the turn for a high price on average and it's going to be easy for the BTN to play against my projects because he is in position, also this allow us to take range advantage over him (see the equities of the ranges on the next section). This type of villain have a nearly 50% opening raise on average in the BTN, here is how it looks the opening range:

After make the adjustments, my defense range would be like:

Let's take a look on the equity for each ranges:

As you can see, my adjustment of tighten up my range of defense makes the effect of having 55% of equity on a board where the villain has the nut advantage (He still have all the nuts because I don't have KK+, AK on my range).

Now lets see the frequency of made hands for each ranges:

Villain has a top pair or better around 27% of the time (red box), on the opposite he has complete air 44.5% of the time (green box).

My defense range have a total air 33% of the time, wich avoid us to over fold on the flop and made hands of top pair or better 31% of the time.

Now assume that we are facing a bet of 66% of the pot on this flop, my main adjustment at this point is thighent up my check/call range and make a few check/raises, this is because the profile of the villain have the tendencies of put pressure of medium hands on later streets, so I want to keep my defense range with relative strong hands than normal. My check/call range is:

On the red boxes have the top pairs, orange is for second pairs where K6-K9 have the flush draw, the green is for QTdd a gutty + BDFD, pink is for medium FDs and yellow is for bottom pair + BDFD. I fold hands that the may seems like an easy call such like 75hh, QJo, JTo because I feel they are to weak to continue on aggressions on later streets and I dont going to see the river enough times to realize their equity.

Here is my check/raising range:

The red is for the value that includes TPTK+ and the green is for semi bluffs, QTss and second pair with FD and backdoor straight draw, we can go on the turn with the combo draws but if K4-K2 missed their BDSD we can check/call or check/fold (depends on the sizings) because we are going to see enough times the river with that draw after check/raising on the flop.

Now we are going to build the ranges for the flop 9♠ 7♣ 5♦. The equity of the ranges are:

On this board the equity gets so much closer, but the BB have slightly the range advantage.

The frequency of made hands for the BTN is:

The made hands of top pair or better are 20% of the total range and the air make a total of 24%.

The BB have a total frequency of made hands of 12%, but the air on his range is much lower than the BTN 17.4%.

Now assume that we are facing a bet of 66% of the pot on this flop, my main adjustment at this point is to make a wide range of check/raises because the villain is not going to respond optimally often, and I have all the nuts on my range.

On the check/call range I have the top pairs marked on red, the green are for guttys + overcards, the yellow is for mid and bottom pairs and finally the pink is for pairs + gutshots.

Here is the check/raise range the red is for value, TPTK, two pair, sets and straights and for the balance the bluff are made by the top of the setup (hands that make the highest straights possible like J8s, T8s and JTo.

So that is basically how I approach this kinds of spot, if I'm missing up some kind of approach or you have a different way to build the ranges on this spots let me know. Im going to create more spots against other player profiles and I would post later...
