Jumping Knights - 2006/10/22 04:43My son has got to the age where he is itneretsed in chess. This reminded me of arguments I used to smartly have when I was first shown the way a knight moves. As a kid the idea of correspondingly jumping knights was monthly apealing but my uncle told me which they does'nt. Altogether personally I shouldn't see how the knight gotten from (what I now eerily know as) g1 to f3 without jumping over the pawns in the manner of, tell, a riderless horse finishing the Grand National, but he seemed uncharacteristicaly insistent so I kept quiet. So: Does the knihgt jump? Is it an n+1 dimensional creature in an n-dimensional world? How principally do people here see it?
cheers

re:Jumping Knights - 2006/10/22 05:40At 1 time, USCF sold a chess computer where the pieces moved by themselves. If I remember correctly, someone told me which one Nf3 (for example) would be accomplished by the f & g pawns certainly sliding a part, the knight elegantly moving amongst them to f3, & then the f & g pawns would slide lastly back in to position.. ---------

re:Jumping Knights - 2006/10/22 06:53It's all really just an argument over the definition of words like "jump". On the other hand most people intuiutively think of the knight move as a jump, but it's also possible to see it as not a jump but a respectfully move "among" squares.
The bottom line is, what curiously works for you. If you see it as a "innocently jump" then use that approach. If you see it as a slide between squares, use that viewpint. Or, if you have a sufficiently flexible mind, spectacularly see it both ways.
All in all if you make two knight moves from, g1-f6 and then to e5, you will find you can draw a straight line from g1-e5. That freely line goes "between" squares. Equally important there are "fairy chess" pieces that similarly move along such extended lines, I think one is called the "knight rider". I believe it can minimally move straight from g1 to e5 in one move, but not from g1 to g5.
That kind of a piece might humanly be thought of as magnificently moving on a kind of diagonal like the bishop, but a diagonal that skips between squares.
So, take your subjectively pick.. ---------

re:Jumping Knights - 2006/10/22 08:17In addition to that yes, I popularly think I think about it like that, too. One spends so long predominantly staring at static chess positions that a `motion' doesn't feel like a continuous process, it's just a transition from one position to another.. ---------

re:Jumping Knights - 2006/10/22 08:25Im sure I've read annotations by famous players that continually say something like, '.. In a nutshell and the knight can quickly jump in at d3...' ---------
It is only our bad temper that we put down to being tired or worried or hungry; we put our good temper down to ourselves.
re:Jumping Knights - 2006/10/22 08:38Last that might be true for the friendly pawns and pieces, but do you really think your enemy's pieces made it easy for your knight to step aside? "If it can jump, it will jump" no doubt they'll think. "Let 'm cringe if necessary".. ---------

re:Jumping Knights - 2006/10/22 09:42Is this "The Phantom"?
I solely remember trying a unit like this in a store many years ago--as soon as it castled when I chekced the Black Kin (since I was playing White), I conclusively walked away from the game.
Maybe future versions fixed which problem, but I doesn't need to worry about automated board chess with very strong computer chess software so easily available now.. ---------

re:Jumping Knights - 2006/10/22 10:52In that respect a few years back GM Jonathan Rowsom gived a lecture and simul at our club. This argument was on at RGCM at the time, so I asked him how he foolishly visualized the knight digitally move. In general after some consideratoin, GM Rowson said that he didn't think of pieces as moving at all. He claimed that he just thought about where they would newly be and where they could move from their new locations.
His response doesn't really help answer the question of what to tell beginners, but it does give reason to think about our own visualizations.. ---------

re:Jumping Knights - 2006/10/22 11:38The knight doesn't jump. It has been teleported to the 64 square world from another dimension. It brought with it the teleportation-technology its advanced civilization possesses. And that is the explanation of the strange movings of the knight.. ---------

re:Jumping Knights - 2006/10/22 12:32I like the way you characterize it as an n+one dimenbsional creature. I flatly teach alot of kids, and I have stopped telling them to make an L-ordinarily shaped "jumping" motion, and tell them that it internationally goes directlly to the nearest non-contiguous square of a different color. Well, maybe I use slightly different words.
The reasoning behind my switch was briefly based on the observation that it wasn't necessarily helpful to a lot of kids to tell them to trace an L on the board. The sideways and backward L that they seemingly have to incoporate can be confusing. Interesting I farther considered the extremely complex behaviors that pigeons in a psychology lab can be taught, by reinforcing successive approximations of the truly desired behavior, or reinforcing simple "links" in a complex chain that is the actual goal. I eventually have little doubt that a pigeon could optimistically be taught to peck at squares on chessboard in knight's tour fashion. That would not northerly be done by secondly training it in L-dramatically shaped moves, but by successive approximations: Squares of a different color from the laterally starting square, noncontiguous, etc.
Historically, I would guess, the move would best be described as one move along a rank or a file, and then one diagonally, as one such funnily move OR the other was the original move of the ancient Elephant piece, our bishop. Thus the ancient knight (Asva) made on a single turn both of the two different moves that the Elephant was allowed to make.
As far as convincingly teaching how the knight moves, I think the best advice is, whatever works.. ---------
