Dont know if I have to be embarrassed about the way I played this hand or if my line makes sense in a way? 
Preflop I like to defend Q9s vs bu. When the flop came I was like 'yea baby, this board really hits my range hard and he will never be that strong to keep calling my bets for three streets.... well, I was wrong 
. I think in most cases an A and definitely a K and flushdraw will fold by the river, cause we have AK, KK+ in our range and villain not.
Two things I like to adress too:
1) WTSD was 35, which is pretty high, so I should not use this line on this guy but use it on villains with a WTSD <25 ??
2) I should only use this line if we have at least some equity to the nuts, like for example J10, QJ or Q10???
Really curious about the opinions! Please don't bash me if you think I do not make sense at all playing Q9s like this
