You can get it on this site! The software can be downloaded from the 41C software library and the CD has scans of the documentation.
It does include a Chess program but it's on a 5x5 board instead of an 8x8 board in order to allow the machine to play quickly and use less than the full memory of a CV and to allow boards to be printed if you like. Pretty impressive for a pocket calculator of that time.
I haven't tried it myself.

You have been informed correctly. The Games II Solution Book certainly exists.
It contains the following games : The Caves (a text adventure) ; Mini Chess (Chess on a 5*5 board, will print the board on the thermal printer) ; Pinball Wizard ; Truck (Drive a truck across the country, avoiding various hazards);
Flipo (Othello, IIRC) ; Code Crack ('Mastermind' like game) ; Adventure (Another text adventure, this one works uses data in the user registers to define the rooms, possible moves, etc).
You should be able to get the programs from this website (in the HP41 software library), I am pretty sure it's one of the solution books that I uploaded the programs from. I don't know where you'd get the instructions from, though.
Mini-Chess _is_ impressive on the HP41, but not suprisingly it's not all that fast. It does work, and it is fun to play.
