BTN seems to be on the nitty side, MP and Blinds look like they are weak passive players however really small sample size so not a solid read by any means.

Unsure about pre, I am pretty sure that I'm going to be playing the pot IP and I don't mind folding to aggression from the BTN. I do think I should be doing this with some Axs, but A6s is probably the worst so may be too wide.

When the flop comes and SB and BB take the following actions I'm pretty sure their ranges are quite strong (I do think some of the below should be discounted like AA, KK, AK, but this is just a rough idea)

If I put SB on a range of {QQ+,55,ATs+,KJs+,JsTs,Ts9s,AJo+,KJo+}
And BB on a range of {QQ+, 55, AK, KQ}

I have 31% equity against this range. I'm just unsure of the best way to play this. I don't think I have a huge amount/any fold equity against the BB and preferably would like the SB to come along too, but at the same time I'm lost if I call, the turn is a blank and I don't see any reason why BB wouldn't be betting the turn.
