Situations/Clarification
From Polarity
Converting Opponents Pieces
You cannot convert your opponent's standing pieces to Foundations of your own colour. When a fault of this kind happens, you resolve the action piece (usually by putting it back in your stack). Your turn ends and your opponent then gets to capture this piece as if capturing a tower.
Mobile Foundations
Foundations can move up to one disc diameter as part of a legal play without causing a fault.
Impossible Captures
The impossible capture is probably the most asked about scenario. Impossible captures are handled as the rules state. If you cause this to happen, the touching discs must be captured by your opponent. In doing so the standing piece falls creating a fault. The pieces forming the tower are placed into your opponent's stack. Your opponent loses his turn and you get to play again.
