Hi,
I have look at my winrate when I call a 3 bet because I had the feeling than I was doing very bad when doing it.
But I have an EV of 161bb/100 hand in this spot (only 867 specific hands of NL20 to 50 wiyh a majority of NL30 it's a near 100k hand database).
That's not a big sample size but the ligne on the graph is stable, so it give me a little confidence about the result.

Is it good or not ?

If it's too good it could it mean 2 things :

That I don't defend enough and my range is very tight so I make money when I call but lost a lot by folding too much ?
I fold 58% on average vs 3 bet and it's near the same for every position (60%) on the button.

Or than I dont 4 bet enough and miss value by not putting a lot of money with very good hand.
My 4 bet range is 1.6 on average with 2.2 on button and 1.7 in SB and my winrate when I 4 bet is 996bb/100 hand (very very small sample size here with only 138 hands).

Is it standard numbers or not.

Because of this numbers, should I defend more against 3 bet ?
