The American task composer

The last part of this month's series deals is about Henry Wald Bettmann (1868-1935) from Cincinnati, Ohio. Together with his brother Edgar and his cousin Jacob he composed chess problems. As teenagers they worked together, in later years only Henry continued to compose, but his professional activities limited his problemistic work.

Bettman was especially interested in task compositions in which some particular feature is presented in maximum or manifold repetitions. Considering the variety of the tasks of which he composed notable illustrations, he may well be regarded as the most outstanding American task composer.

One famous example is the Babson task. Bettmann showed the first problem in which a single black and single white pawn were involved in the promotions. You can have a look at it here.

Another composer from Grand Rapids

Let's now turn towards another pioneer of chess composition, Otto B. Wurzburg, a nephew of Shinkman. Not only did he display outstanding skill in construction both strategic and model mate compositions, but he was also a strong chess player.

Wurzburg composed very many spectacular chess problems. Surely we all have seen at least some of them as they have often been reprinted. One interesting fact is his sparing use of white pawns. Did you know that? I was quite astonished when I learnt it. Maybe, I haven't seen enough of his work, yet. And quite possibly, I haven't paid a lot of attention to such things.

The last thing to mention is the theme that is named after him, the Wurzburg-Plachutta. You can find an example here.

The Wizard of Grand Rapids

Along with his contemporary Samuel Loyd, William A. Shinkman was the best known composer of the United States in the late 19th and early 20th Century. Did you know that he also used the pseudonym M. Ham Nawki? He composed some thirty-five hundred problems which makes him the most prolific American composer. Shinkman contributed a lot to the area of selfmate problems, but I'll stick to the regular mate in three or more moves which often have a surprising key move.

Loyd frequently was content with showing a single example of a theme whereas Shinkman experimented with various illustrations of it. Alain C. White wrote: "Loyd toyed with themes, Shinkman masters them."

We see a Plachutta interference with only eight pieces, another example of Shinkman's outstanding ability to illustrate a strategic theme with a minimum number of men.

Samuel Loyd

In February, I start another little series. This time, I write about some famous American problemists starting with Samuel Loyd.

Of course, you can find tons of information on the Internet and in books. So, I won't bore you with things you might already know and just pick a few details regarding his life and his compositions which I consider to be quite interesting.

I read that early on he showed a liking for mime, ventriloquism, magic, card tricks and sleight of hand — and chess. He became interested in chess problems before entering his teens. This might apply to many problemists among my readers, I don't know. Anyway, I see myself in it.

By the age of sixteen he was America's leading composer and magazines worldwide published his problems. He was incredibly productive but nearly stopped all chess activities before the age of twenty because he was about to become the Puzzle King.

There's a similar course of events in my life. Several years before my first original was published, I had composed very many problems just for myself. Sure, there was a lot of rubbish, mainly incorrect and anticipated stuff. Nevertheless, some nice things were left and until about the early 1990s, I created more and sent in the works. But then, similar to Loyd, I concentrated on something else. In my case it was correspondence chess that occupied me so much that I rarely composed new problems and just used the material from the previous years.

Only in 2010, I had sort of a comeback and since then try to be more active again. I even got inspired by doing research for this blog. However, I am still heavily involved in correspondence tournaments of high(er) categories and for the national team. Being close to the GM title, it's hard to not try to get the required second norm.

Back to the Master who introduced lots of new ideas and forms like twins and retros. Moreover, he was the first to show the Plachutta interference and he composed the first correct(!) example of the Turton doubling (Turton's version some months ago turned out to be unsound). Now, let's enjoy some of his chess problems!

A set of three problems was the required entry for each participant in that tournament.
The motto for Loyd's set was "Certum pete finem". Easy to spot that this three-mover is a prototype of the famous "Steinitz-Gambit" problem which was published only 46 years later.
