# New solution to the Lucena position

Hi Guys

I was playing the Lucena position vs rybka when I suddenly found a completely different solution that always works!

This is an old solution to the Lucena position

Well, in my endgame book by GM Flear which analyzes all solutions of the Lucena, there wasn't this. I didn't plagiarise but if it already exists,I'm glad I found it out by game analysis

I believe you found it yourself, but this is a known alternative method. Somehow the other way is believed to be more instructive.

Sorry, Vyomo, that is not the Lucena Position. You had the R on the g-file.

In the Lucena Posiition the R is on the h-file.

Because Black's R is not on the h-file, there is no need to build a bridge as in the Lucena Position.  A straight 1.Rh2 wins. For example 1...Rg3 2.KH8 Kf7 3.Rf2+ K-any 4.g8=Q wins

What "old solution" were you refering to heinzie?

The position you are referring to is not the Lucena Position because the R is on the g-file, not on the h-file.

Of course there wasn't your position because your position is not the Lucena Position.  The reason White has to build a bridge is because Black's R on the h-file prevents White's K from escaping to the h-file.  In your position a straight 1.Rh2 protects the K from a check and therefore there is no need to build a bridge.

What "known alternative method", heinzie?  The position you are referring to is not the Lucena Position.

As has been said, the original diagram isn't a lucena position.  The bridge solution would be when the h-file is already guarded by the black rook... there isn't some more straight forward solution that doesn't get taught for the sake of 'instruction' lol.

I'm fairly certain M. Dvoretsky points out this alternative method in his endgame manual, and I've seen it used in practice as well.

Indeed there are positions that claim to be the  "Lucena Position" except that it is not the Lucena Position but a variant.

For example, if the "Lucena Position" is moved to the center then there would be alternatives to the  Lucena Position solution of building a "bridge". There would be many alternative solution to creating a bridge such that the solution given in the diagram is not the only solution but there are several other solutions as well.

Why do they call it a "bridge?" Wouldn't the word "shield" be more appropriate?

DrFrank124c, I've had trouble understanding the term "bridge" too.  So I reread the section in the book My System by Nimzowitsch.  I believe he meant that the white king finds shelter from the rain of black rook checks under the bridge (white rook).  It's confusing because the rain normally falls vertically.

When we use the word "bridge" we are referring to something that enables us to cross over something usually a river, sometimes a highway. In some cases a bridge has a secondary function as it sometimes provides protection from the rain, in this case from the rain of checks. From time to time we find homeless people living under a bridge due to the protection it provides against the rain. That is the sense that Nimzowitsch intended, I suppose. Maybe Nimzowitsch was homeless at one time or other, could be because he was a gambler living off his winnings from chess. So maybe Nimzowitsch was telling us something about his own life. But the word "shield" would  be  more appropriate since it "shields" the King from the checks of the rook.

I think this is only possible after innacurate defence. If the Black rook was on h1 then you'd have to build a bridge by getting the rook to the forth rank.
