hi,
the Open Raising Chart SH NL is only telling when to raise if no player limped (or i suppose i might add loose limpers here as well).
i am at a loss here however on how to react to raises in front (as the FR chart does)
or how to react to a a tight limper....
or from what pocket pair on to raise if several limpers in front....
this and a few more.... 
I think he's referring to specific situations when you reraise/call raises/raise limpers or just call...
Hi Floating!
That depends a lot on your opponents and on your position. It is impossible to make a complete chart about the preflop game at SH tables. You have to adjust your game to your opponents and the dynamics at the table. Maybe it helps if you watch some live coachings?! Ask the coaches why they raise or call in that specific situation with that specific hand. This way you will get a feeling for the preflop game at shorthanded tables.
Good luck at the tables!
