I got Spenda to admit what he was after so it would be cheating to mention it now, but its outside the box of the normal "continuing with a marginal hand" type of situation. In fact even after he told me I still kinda see it as different although technically correct. Think about different player types, not just pure fish and when they might do this.

I dont think its as simple as saying "work out their range and exploit it". One of the harder things to do (at least it was for me) as a beginning player was to work out HOW to exploit someones ranges. Given the way I've seen some "regs" attempt to exploit people I'd say thats fairly universal, because as a rule most people suck at all bar the most basic examples. Thats why Spenda talks about giving it some real thought and not just typing the same canned response everyone knows by rote.
