Cannot cast inside the Action<T> parameter of Verify method

[BlueHydrangea2908]

I met an exception when trying to run the test that have the following code. When I try to make an expression that using a cast, this exception was throw by Moq: "System.ArgumentException : Unsupported expression: (IObserver<IMove>)player". Why Moq don't allow to cast in this situation? Or I'm writing the test code in wrong way?

collectionOfMockForPlayer[1]
    .Verify((IPlayer player) => ((IObserver<IMove>)player).OnError(It.IsAny<MatchManager.IllegalMoveException>()), Times.Once());

Verify is used to match against invocations on the mock. Casting the object to another type does not involve any invocations on it (by default, unless you're trying to test an override of an implicit or explicit cast). Is that your scenario?
