Solutions to Tour Puzzles

I've published a set of tour puzzles on the Knight and Leaper Tours subforum. Moves at the top of the 6x7 board (Diagonal, Lateral or Right angles) are given and the puzzle in each case is to complete a symmetric closed tour. 

Knight and Leaper Tours - ChessProblem.net

To avoid having the solutions on the same page I thought it might be better to publish them here and provide a link to this page, to allow time for people to solve the puzzles.


The solutions can all be reasoned out step by step. For instance the paths through the corner cells are fixed, and in most cases this is true of other cells. Another factor to watch for is where putting in a pair of opposite moves (to satisfy the symmetry condition) results in a short circuit (i.e. not a complete tour).

Chess at Great Yarmouth

 On Friday 31 March I took to the trains to Great Yarmouth, travelling via Nottingham and Norwich, to take part in the chess congress. This was probably a bit too far to travel in one day and left me quite tired. The bed and breakfast accommodation I had booked was comfortable however.

The weather on Saturday was wet and windy and cold, and getting to the Conference Centre venue, at the race course, was a long walk. Nevertheless I began with a good win against a 1500 rated opponent. This was followed by a draw. I was unable to find a place nearby for a decent meal and had to settle for a take-away coffee and pasty. 

By the time of the third round that evening I was quite tired and found I had to play a strong Junior. Unfortunately she kept coughing at every move, which I complained about to the organisers, and questioned the state of her health, but they said she only had a cold, not Covid. It was a long game and in the end I ran out of time.

On Sunday morning the weather was much better, sunny but still with a strong wind. I lost my morning game by playing all the wrong opening moves. Fortunately this gave me time to catch a No.8 bus into the town centre where I was able to get some cod and chips at the Fish O'Licious by the bus station. Surprisingly for a seaside town there didn't seem to be many fish and chip shops, but maybe it was out of season. Most places along the front were closed up.

I caught the bus back to the venue, arriving in good time, and in a good mood, to win the final game, also against a 1500 rated player, though I think he was very tired at the end. 

So my score was 2.5 out of 5, which I consider my standard result. The chess results website rates my performance at the 1460 level, well above my current rating of 1311. 

The journey home was uneventful but I needed a good sleep that night. I will have to look at the chess calendar to see whether there is another event I could enter before the Crewe congress at the end of June. Maybe I should try some rapid play.
