www.chessbet.com allows its users to predict the outcome of chess events for free. We now want to create a logo which can replace the current logo on the site, and which also can be used in online banners. The logo should fit with the current website layout. We're thinking about something which symbols the unknown outcome of a chess game. For example the silhouettes of two chess players who ponder over a chess board marked with a question mark.
Attached is a banner we used before, which might serve as inspiration.
