What exactly is the Budapest Rook, or the Budapest Rook lift?

Anybody got examples?

Thanx Mike. I'm at work now, I'll go check my DB at home later.

I found this game by Johnny Hector (who's fast becoming a favourite of mine!)

I will definately have to incorporate this into my game play

If I remember correctly, the idea of lifting the rook via a6 ("Budapest Rook") to the centre or kingside is what led to a revival of the Budapest Gambit in the 1980's. Black has won some spectacular attacks with the setup Ra8-a6-h6, Qh4, Ng4. Especially, since White has to make do without a knight on f3.

Here's a gif to illustrate the intended path of the Budapest Rook:

The manouevre is pretty cool, but there are some serious drawbacks. For one thing, you have to hold back d6 until you've slid over the Budapest Rook. Which is unfortunate, because we need that pawn move in a ton of variations. Also, a timely attack on the dark squared bishop can disrupt the plan. It may find itself retreating to a7 and even b8 (to cover c7) where it will be excluded from the game.

In the end, though I have some variations in the arsenal involving the Budapest rook, I have never been able to utilise it to full effect in a serious game against a strong player.
