Actually, it is a mate in any possible play, so...

Yes, it is mate in 2. The position was unavoidable.

It was a very interesting game. Thank you.

You're welcome.

Because you said that your old age does not allow you to play blindfold chess, how did you visualise the moves here?

I used a board and pieces just like everyone else.

How much do openings affect the game?

The opening is an extremely important part of the game but no more important than any other.

Well, which openings are among the most often used?

The Sicilian defence, Ruy Lopez, Kinds Indian defence, Gruenfeld defence have always been mainstays.

But you are often better off playing something that is better suited to your style then to what everyone else plays. Also picking offbeat openings can result in confusing the opponent.

Yes, I read about Kasparovski using an a3 opening against a computer to confuse it.

I thought about using a fianchetto opening, but it seems too weak.

The Kings Indian Attack is a fianchetto type opening that was used by many strong players. It is not weak, it is just not fast.

That is right, followed by Bg2 and 0-0. Great for producing heavy maneuvering and easy to play. Favorite of the great Tigran Petrosian.

Hm, I like that one.

Why is Sicilian defense good against that opening?

The Sicilian defense is the most popular response against 1e4, not against the KIA.

Yes, but, you can begin KIA with 1e4.

You can transpose into a Kings Indian reversed but it is a trifle limited to do it that way.

It isn't, it is a good choice for aggressive players against 1e4. The KIA is not 1e4.

It creates an unbalanced position as opposed to 1e4, e5. The play leads to great complication in an open position where one side will win. The chances generally favor white but black has lots of counterplay. In other openings black has a more solid but more timid position.
