I play low stakes and sometimes I see people calling when i'm the BB and I just check because my hand is not so good. What then happens on the flop is that I don't have a read on the opponent range, and when I go to showdown sometimes I see the most random stuff.

My point is that when an opponent raises I can put him on a range witch which he would do that. (I'm not very experienced, and the way I do this is by adapting my range on that position to the type of player I think the opponent is, I'm not sure is that's the right way to do it.) But when he just calls I usually have no idea.

For example this hand:

PokerStars - 15/30 Ante 4 NL (6 max) - Holdem - 4 players

CO: 57.77 BB (VPIP: 50.00, PFR: 10.00, 3Bet Preflop: 0.00, Hands: 10)
BTN: 158.37 BB (VPIP: 50.00, PFR: 30.00, 3Bet Preflop: 0.00, Hands: 10)
SB: 43.9 BB (VPIP: 6.25, PFR: 6.25, 3Bet Preflop: 0.00, Hands: 16)
Hero (BB): 39.97 BB

4 players post ante of 0.13 BB, SB posts SB 0.5 BB, Hero posts BB 1 BB

Pre Flop: (pot: 2.03 BB) Hero has J 6

CO calls 1 BB, fold, fold, Hero checks

Flop: (3.03 BB, 2 players) 8 9 T
Hero checks, CO bets 3.03 BB, Hero calls 3.03 BB

Turn: (9.1 BB, 2 players) A
Hero checks, CO bets 4.57 BB, fold

I called the flop because I fell like I have a lot of equity but I'm not sure what the villain has. Because of that and because it's early in the tournament I decided to fold the turn but I still have no idea of what his hand was.

Fold Flop

Imo, you're in the right line of thinking it, you just have to go forward on it.

If the villain limp pre-flop, he can also be putted in a range, it's (almost always) wider than a range of a raise, in this exercise you have to also take off of his range, all
the comboss that this villain would raise. Normally it's something like excluding the premium hands and the top combinations.

The way you play at BTN against it when you have a weak hand is exactly how your hand strength and ur disvantage of position deserves, in that example, and most of the time in a passive way. You're out of position with a good equity against his wide range, so try to realize ur equity, if you put this hand of ur example against a wide range, you for sure have something like 40%+ so it's really not bad to see the flop and you can even pay 1 or 2 streets, seeing how ur hands goes against most of his range. If the villain is very passive you can also take the action if you got something.

In this example, I just would also fold flop even having a good equity because he has overbetted the flop, not giving you the odds to pay for the pot. And seeing that you're not sure if he would give you any more chips if you hit your straight, doesn't look so attractive to pay for it.

Hope it can someway clarify ur ranging process.

This helped a lot thanks.
