Has this been played before?

Post by Gerard Killoran » Wed Aug 10, 2022 3:43 pm

In this game, my opponent has just played Rg2-e2 hitting my Knight, but losing his Rook. It's a simple, but easily overlooked tactic.

I feel there must be a previous example of this, but where?

I've seen similar themes in tactics puzzles but this one is quite nice and unique as it chains pins and discovered attacks from apparent weakness into a winning position
Lose one queen and it is a disaster, Lose 1000 queens and it is just a statistic.

You might find examples of that tactic in composed positions, maybe in a sideline or mainline of an endgame study?

Not only famous for a dodgy opening but also on the losing end of a famous tactic - the legacy of grob becomes ever more dubious...

And now we know the theme of this weeks puzzle. All you have to do is set it up.

P. Welz - A. Wenzel, Berlin Open (3) 2009



White to play.

The lines after Qxf3 are quite interesting too, and pretty relevent to calculate correctly otherwise white just lost a piece without getting the tactic

That's just what I needed, more proof of my unoriginality.

I would say the contrary is true - if you had never seen this pattern before and still found the tactic it means you actually figured it out over the board with your own brain which is far more commendable then winning though pattern recognition or memorised theory.

Hi Joey,

I think you are correct, if Gerard had seen it before perhaps he would not of have posted.
I'm pretty sure I've not seen the pattern before. a 6th rank Rook check forcing the King
into a Knight check allowing the Rook to potentially pick up anything loose on the file.

I found the one on chessgames on a different database which is a single database just
full of games from their site. The annoying thing is they save their games using the full name.
For example if you search for 'Fischer' you get nothing, to get Fischer's games you try a
search for 'Robert' and then you get everyone called Robert on their database.
So you have to enter 'Robert James Fischer' which is OK if you know (and how to spell exactly)
every middle name for every player who has ever played a game of chess.
