BIG BAD WOLF: Actually it works great with the random piece placement. Here are the rules from SchemingMind.com:

SunTzu Chess

Inspired by the great war philosopher SunTzu, this variant combines three previous variants into one game that simulates the fog of war.

The first thing you will notice is that your pieces are (likely) not in the normal chess configuration. The pieces are set up according to Fischer Random rules, however unlike Fischer Random Chess, black and white have different starting positions.

The second thing you will notice is that you can only see your half of the board when you start. That is because you can only see your opponents pieces when they are in your 'searchlight' (you can see which pieces you have taken). Your opponents moves are displayed as question marks, however these will still be appended with '+' and '#' for check and mate.

The third thing you will notice, and this will come as a real surprise if you haven't read these rules, is that pieces you capture become yours to use as you wish on a future turn (and vice versa for your opponent). You can "drop" them anywhere on the board including checking the King. Pawns cannot be dropped on the 1st or 8th rank, and if a promoted pawn is captured, it reverts back to a pawn, so be sure you know which Queen you are hunting!

One special note, after you capture your first piece, you'll be able to see all the free squares available to place a piece. This is a large tactical advantage because it gives you the terrain. However you still have very little idea which of the dark squares represent which enemy pieces!
