Is a player required to correct their opponent's miscalculation of available energy when the opponent mutters to themselves but doesn't directly ask, and what information must be provided when asked about energy?

Ruling: You are not required to correct your opponent's self-mutterings or miscalculations. When directly asked about energy, you must provide public information (number of ready runes and cards like Energy Conduit), but you are not required to calculate the total energy amount for your opponent - that is derived information.

Sequence:

• If opponent mutters to themselves without asking you directly, no response is required
• If opponent asks "how much energy do you have available?", you can refuse to answer, or provide public information ("1 rune and 1 conduit")
• You are not required to do the math and say "2 energy" - that calculation is derived information
• However, if you choose to answer with a number, it must be accurate or it becomes angle shooting/lying

Nuances:

• Saying "I have 1 energy up" when you have 1 rune and 1 conduit is considered lying/angle shooting and is punishable
• Being technically correct but intentionally difficult may result in unsportsmanlike conduct warnings at judge discretion
• Standards may differ between local events (more communication encouraged) and high-level competitive play (stricter adherence to derived information rules)
• Floating/pooled energy must be indicated clearly with a die or verbally
• If opponent calls a judge to help read the board state, that's their right, but calling a judge for simple math (1 rune + 1 conduit) may result in a slow play warning for the caller
