Preflop play
Hi im a NL25 player and want to sharpen up my preflop play. After all preflop is where everything begins. I want to split Preflop in the following categories:
-RFI
-Cold Call
-Isolating limper
-3 bet
-defend vs 3bet (call 3bet or 4 bet)

First I would like to start with analyze RFI. When I know RFI ranges and understand when to deviate I will generate money because this spots happen so often. Also it will give confidence and I will make less mistakes postflop. It will create a snowball effect.

In the charts I will have a Default range and a Widen Up range:
Default Range:
This is the safe range.
I will use the default range if the players are unknown.

Widen Up range:
Due to weaker player types I will widen up my range.
This is the range I can play when there is Fish in the blinds, or passive 3bettors.

Next im gonna show the openingranges I made. I hope some of u would like to take a look at it, and maybe give some advice or discuss about it.

UTG
Default range = 12,2%
Widen Up range = 17,9%

Im curious if my default range is too tight. Would u put all pocket pairs in it? Or more Ax suited?
Do u think my Widen Up range is ok? Or do u like to put some suited gappers in it? T8s, 97s?

When do we want to Widen Up. I made some scenario to ask u what u would do.
We are UTG , MP = Reg, CO and BTN = Nit with low 3b SB= Reg BB = 52/12 callstation

I think we can open all of our Widen Up range here because the BB is most important position because we have position on it and bb is fish, also the positions CO and BTN will play straightforward and not 3bet bluff. Only downfall is MP and SB are Reg but they will not attack UTG range so much, so it’s not that important. What is the bottom u would open in this spot on this table?

We are UTG, MP CO BTN = Reg SB BB = 52/12
How does your RFI look like?

And how does it change when there is a 62/50/20 whale in the BB? The rest of table is Reg.
We go back to our default range or is there some widen up to do?

Tomorrow I will have look at RFI MP
