Sir Alfonso the Fingerless’ Guide to Knife Poker

Ye Olde Fool’s Guide to Poker Of the Sharper Variety is a universal ttrpg supplement which describes the fictional game of Knife Poker (please do not play this game in real life.) This document is intended to be an in-world guide, and can be modified to fit any medieval-ish setting. 
Knife poker as a game is a high stakes version of traditional poker, and is best served as played by extreme, slightly humorous rogues and rascals of all varieties (or more likely suggested at and referenced but never actually engaged with by the players). Perhaps a particularly nefarious institution has a game of knife poker going on in the corner, or a dastardly rogue references his Knife Poker days. This can be an easy way to add an absurdist twist to your setting.
