I'd want to see your raise first in (RFI) stats to really judge. BTN VPIP looks low to me.

I don't think Drive HUD provides actual RFI stats, but I can calculate my RFI based on my opening standards as follows.

RFI:

EP 13.27%
HJ 18.36%
CO 30.69%
BT 36.86%
SB 58.3%

BTN is still way too tight. I open ~44% and I'm viewed as somewhat nitty.

I'll make some adjustments to my standards. The other positions seem okay?

Point of clarification:

When we say a player's RFI is 44% on the BTN, which do we mean?

44% of the 169 possible suited, non-suited, or paired hands (which would be 74 of the possible hands on a start chart) ...

Or

44% of the 1326 possible combinations (i.e. This gives weight to the different types of hands: for example there are 6 TT, 12 T8o and only 4 T8s hands). Makes a difference. I think it's the latter since the stats measure the % of all hands dealt to you of the 1326 possible 2-card combinations.

Guess I never thought how an equity calculator figures it when we tell it 44% of hands.

To illustrate: All paired hands comprise 13/169 combinations or 7.69% but 6*13/1326 possible two-card hands or 5.89% depending on how you calculate it.

Without reads on the blinds and with a 100% cbet strategy, I suggest playing somewhat tight like 40%-45% on the button.

With reads on the blinds and with a <100% cbet strategy, I suggest playing somewhat looser like 45%-55% on the button.

Wow, that seems like a lot more that "somewhat" looser. I guess it would make a lot of sense if your read on the blinds is that they fold to a steal too much. But I think you mean more that that when you say "with a read on the blinds."

Yeah, I mean with good reads on postflop tendencies we can get way outta line even vs players that call way too much. Put a tighty in the small blind and a standard tagfish in the big blind and I'm probably opening 75% or so.

Am I correct that such a broad range opens us up to exploitation, and if the blinds adjust to exploit us we have to pull back a bit? If I were the blind and someone was doing this to me, I'd want to punish them with lots of 3-betting.

Most definitely. Thankfully most players are set in their ways. Tight passive personalities have a particularly hard time loosening up imo.

In fairness to DriveHUD (and I do very much enjoy their product), I have to correct myself. They do provide these stats by different name so I didn't recognize them. I think they call them UOPFRxx% (Un-Opened Preflop Raise where xx designates Position).

CO looks good. HJ is ok. BTN could be 10-15% wider. EP could be 5-7% wider.

EP is trending upward. This month now showing 17.8%. I've adjusted my standards from BTN so that should show drastic movement over the next month.

I started at RFI EP 13.27% taking Stox's standards as gospel and have not budged from that (yet).

Looks like if I expand EP to 18% as you suggest, I'd have to add hands that include A5s-A8s, Q9s, J9s, KTo-KQo, QTo-QJo. Really? I "feel" okay w/ the Axs and KQo, but off-suit Queens? Just need some reassurance there.

And if EP moves to 18% I suppose my "okay" HJ may need to slide toward 22%-24% or so?

I do have to say, even in just 3k hands, that I'm noticing a great difference being in more pots. Easy to see from this side I was just sitting on the sidelines way too often.

I open all of those hands from EP/UTG 6max. My default CO range is 20%. I wouldn't go much beyond that or you could just keep your current CO range and be fine until you're more comfortable.

I assume your 20% is from what I've referred to as HJ and not CO, correct? My CO range is around 30% which you said looks good. HJ is currently just over 18% and if I don't expand it a bit will be the same as my EP.

My default ranges are BTN 50%, CO 30%, HJ 20%, EP/UTG 18%

I mistyped earlier.

This all helps. I'm pretty comfortable with adjustments I've made for now. New target ranges are BTN 46%, CO 33%, HJ 24%, EP 18%. Then there's the SB which I've adjusted to 63% with a favorable BB player behind me, moving up or down depending on the BB.

Sounds like I may be at risk of opening a few too many hands in HJ but I'll see how that goes.
