Schnapsen Bot Strategy Analysis

About This Project

This project measures risk-taking vs. laid-back strategies in the card game Schnapsen. We extended the Schnapsen framework by adding two rule-based bots and benchmarking their performance.

What We Added

1. RiskTakingBot (Aggressive Strategy)

   • Prioritizes high-value cards, trump exchanges, and marriages early.
   • Always attempts to win tricks when possible.
   • Location: src/schnapsen/bots/aggressive.py

2. LaidBackBot (Passive Strategy)

   • Conserves high-value cards for later phases.
   • Minimizes point loss by playing low-value cards first.
   • Uses trump cards only when necessary.
   • Location: src/schnapsen/bots/passive.py

How to Run

1. Bot Tournament:
   Execute bot_comparison.py to run matches between bots:

   python executables/bot_comparison.py  

   This script runs 1,000 games between:

   • LaidBackBot
   • RiskTakingBot
   • RandBot
   • RdeepBot

   Results (win rates and scores) are printed to the console.

2. Reproducibility:

   • A fixed random seed (seed=155) ensures reproducible outcomes.
   • Adjust myrepeats in bot_comparison.py to change the number of games.

Customization

• Add/Remove Bots: Modify the bots list in bot_comparison.py:

  bots = [bot1, bot2, bot3, bot4]  # Add/remove bots here
