Nice set Jack. What size board are you using in this picture? And, out of curiosity, what are the diameters of the king and pawn?
I too enjoy club size sets -- where space allows (I have one 4.5" and three 4.25" sets). I play a lot chess in coffee shops where the tables are just too small for anything larger than a 2" board, or a 2-1/8" board without a frame.
At times, where I can accommodate a larger board, I have a 20" board with 2.5" squares (sans frame), that I use with all of the above sets. All the kings have a diameter of approximately 1.9", resulting in scaling factors of between 75% - 76.4%, which looks just about right to my eye.
Club sized referring to chess sets in the 4.4" to 5.0" size for a King. The imposter "small club" size of 4.0" need not apply.
I like them.
Some people say they are a little hard to take in at once, but I feel like it's only a matter of a couple of games before anything like that becomes a non-issue.
They are not very portable, but they are portable enough. I take my home-made budget board with me in the back seat of my car to my friends house to play on a twice a week basis and carry my chess pieces in a plastic tub.
I feel like they have an air of theatricality about them, and family members and bystanders tend to become more interested in chess because of it. If you are short on potential over the board opponents this a good thing. If you don't like people fussing over your game this is a very bad thing.
The best size for a club sized board is a 2.5 to 3.0" board. I use a 2.75" board and a 3.0" board as I fancy on a particular night. If you use a Jaques reproduction or some other more stout looking set 2.5" would probably be the best. Nothing smaller! (sorry Alan).
