A 9x9 board is the recommended board for beginners (or any Go player looking for a quick game, e.g. during coffee break...). The reduced size allows for shorter and simpler (not easier) games. It is a convenient size because it can be played on the lines of a Western Chess board (which has 8x8 squares, thus 9x9 lines).
Tengen, the middle of the board, is an obvious first move. In 9x9 Go tactics are important. Strategy doesn't really apply. Less complex than 19x19 Go, it still makes an interesting challenge for professionals.
