Chess board in tournaments
According to the book it is easier to distinguish occupied and unoccupied spaces if your dark squares are a different color from your dark pieces.
Well, I did the easy thing, I tried putting the black pieces on the black squares. Hard to see them, so looks like I'll be getting a new board.

It is also said that the green/white combo is easier on they eyes than others, like the blue/white and red/white boards you see occasionally.

I dont think it will be a problem.
For televised chess, yes, green is nice since its easy to see the pieces, but I think you could take your black and white to a tourney and be fine.

Extreme contrast between white and black can hurt the eyes after 5-6 hours of staring at a chessboard.

My board is black and white, and I've never had a problem seeing everything. I did have one opponent who insisted on using his green and white board, though.

At any chess tournament in the US, the odds are high that both players will bring equipment; if you are assigned black, you get the choice. Your opponent can make a claim that your board is "non-standard" demand to use his own; but unless your board has a super-shiny finish or something I doubt a tournament director will make you change it.
If you bought it online, could you post a link?

I'd like to always use my pieces and board in tournaments. They are the right size and proportions and very matte--equipment that would be good for everyone. I realize, however, that my opponent may invoke his rights and force worse upon me, with the TD even siding with him in marginal situations when the equipment is rather sucky.
Since that can happen, it's good to be flexible. When I end up with a lousy set/board I just accept it as an opportunity to practice in conditions that can arise at any time.

I've been told by players who use my vinyl "Oak & Maple" board that they don't want to play on anything else, because the colors and textures are very relaxing. I would have to agree.

Hmm... a vinyl board with the colors of wood. I'm actually surprised I haven't seen such a thing before. It seems like such an obvious idea, but I didn't think of it until you pointed it out.
I realize this is an old posting but I need to get my wood and marble chessboards prints more coverage. My current boards come with walnut,walnut burl,cocobolo, ebony, brown marble, red, and green colors that are all printed via sublimation process on a soft and flexible polyester material with a 1\16 inch rubber base. They are easy to transport because they roll up very nice and retain their bright color.
If you have wooden pieces that you wish to play with in tournaments, my boards are your answer. The 2 1\4 inch square size is the same as most tournaments see used and meet the USCF standards.
I will try to post some cf my boards jpg pictures later today.
Back when I did OTB tournament play, there was quite a bit of variation in what equipment different players used. Silicon boards hadn't been invented yet, most players had vinyl or mousepad boards in a variety of colors. I remember seeing a few paper boards (like cardboard checkers boards) too. Dark colors were mostly green or black, but I saw a few red and at least a few brown boards too. It was rare to see a folding wood or single piece wood board, but they did show up from time to time.
Chess pieces were almost universally plastic, though occasionally someone would bring a nicer wood set. Never saw a "luxury" set with highly detailed carving... I guess people were smart enough to know that those would get trashed!

If the dark squares of the board are the same color, or nearly so, as the dark pieces, then those pieces will be camouflaged by the dark squares, making visualization of the positions of the dark pieces/pawns on the board suboptimal...better to have some contrast between the dark squares and the dark pieces....the more contrast, the better in this regard...
An example of what I'm talking about...(here, they're playing on a paper board)....

In this regard, I recommend this FlexPad rollup boards from ChessHouse. The dark squares come in a variety of colors...

Be sure to roll any rollup board with the playing squares OUTWARD, and store the rolled up board in a mailing tube (cardboard or plastic)....this will accomplish two things - rolling the board with the playing squares outward will ensure that the board will lay nice and flat when playing (i.e., not curled up around the edges). Storing rolled up in a tube will prevent the board from wrinkling and warping, ensuring a smooth, flat playing surface when in use.
I was reading the USCF rule book, and it said that in tournaments, most people use chess boards with white and green squares. I just bought a chess board with white and black squares. Is that still ok to use? Thanks.
