I see your point Barry, coming over his 2x open feels weird as usually we're setting this up to jam with this stack with 8,9bb's rr or so... I dunno, does that mean we can flat and see a flop, not many make us feel great... with an ugly stack to be oop. Without reads I'd prolly flat, fold anything I don't crush due to lack of originality with that 2x open and stacks.. I almost hate it thinking there's better +EV here somewhere though...
The 1800 rr leaves us with an odd stack to pot ratio.. he calls, checks a rag flop, you? (cbet, he pops you fold...???) I think if we're doing a play based on stacks, we should get the stacks where we want them post flop, as a cbet commits us anyway. The 2.5k gives us a little better chance to take it down right here, and leaves us plenty to make him go away on the flop.

I think I'd either go with the play to 2.5k, calling a shove / jamming most flops or fold/flat. With the read I like the go n go.
one note though, the flat can help keep the 2x raising hounds off us too.
