ISB Investigation and opponent card in the same round

[Priv_IRA]

A player "A" plays Agen Kallus Pip 2 "ISB Investigation" and a player "B" PIP 1 e.g. "Ambush" 
The player "A" declares number 1 as his ISB Investigation card effect. 

The payer "B" card "Ambush" is on the table and no longer in the player's hand - does it stay as the played card for this round and only one remaining PIP 1 card is affected?

Hello,

The ISB Investigation command card has the opponent set aside command cards in their hand that have a number of pips equal to the declared result.

As the 1-pip played that round in your example is not in the opponent's hand, it is not affected by the ISB Investigation command card.

Hope this helps,
Seth
