Basic Checkmate
1. King & Queen v King
- Overview -

This image shows an example of the sort of position a King & Queen need to take up, to Checkmate a lone King.

All of the Black King's move-options are guarded (red squares), preventing his escape.

I've also highlighted the additional square coverage of White's Qe7 and Kf6 (yellow squares), just to show what the Checkmated King was up against.

Note especially how White's Qe7 effectively locks-down the entire 7th Rank, with Kf6 securing the e6-square - the only square his Queen doesn't guard (remember, Ken Wilsdon's 1st Pattern for Control of a Square: "Occupation is not the same as Control").
