So this is how I do it:
Ensure the silver.exe command window is open
1/ Start HR, then press the "D" button in HearthRanger
[this will open the debug rules window]
2/ Press "Reload Rules" button within the Debug Rules window
3/ Assess what the Silver.exe command window recommends/debug window
4/ Either intervene/manually play a move or Press "Continue" if you want HR to execute the move Silver recommends.
NOTE: If you execute a move manually, always press the "Reload Rules" button to have HR/Silver.exe recalculate it's next move.
