On the second hand, I've often had trouble making that call.
Not becuase I usually look for straight flushes to flat call, but becuase I often think that it sets off lots of red-flags when you check call a raise and reraise.
I've seen people call with weaker than QQ to a push there, but I've also seen people not very alarmed at the flat call. Just wondering how you usually play it.
