A name for a check-assisted discovered attack?

I read somewhere that the tactic of delivering a sacrificial check as a means of executing a discovered attack on a more valuable piece is called a "tie." But no glossary at which I have looked includes the term. For example:

FEN: 1r5k/p3rb1p/B1p3p1/2N1qp2/3n4/1P3P2/PQ4PP/4RRK1 w - - 0 29

The moves: 29. ...Nxf3+ 30. gxNf3 QxQb2

Is there a name for this tactic?

There is no special name for this kind of tactic.  It is still referred to as a Discovered Attack.  Perhaps there may be one created in the future, but for now it holds the same vernacular.

Thanks.

I think I will call it a check-assisted discovered attack, a "CADA" to distinguish it from a regular discovered attack.
