Ive seen it as high as 470 dollar buy in, and just read gus hansen book and he raises with these types of hands, So yes i think we will always see someone fliping Q7s, over at the end of a hand. Defending aginst it at the low levels, is kind of impossible, as stated above a paired board= opp shoves, on flush draw. I believe he'd even called if opp had ckraised. (you shouldn't draw for flushes with a paired board). Thats kinda hard, all you can do is bet enough to make their odds
for drawing wrong, and if they push on the draw, then if you have two pair, or a set, i call for sure- as you have some out if its a bad turn, and you could turn him dead as well. For other hands (top pair, over pair)thats on you to decide. To me it depends on how much the pot is to my stack, current blind level, thoughts on my opp, etc..
