BEAROFFDUMP(6)

💖 BEAROFFDUMP — games manual, section 6, bestie edition 💖

okay so this is bearoffdump, straight outta the Games Manual, section 6. she's a little command-line girly who peers into your GNU Backgammon bearoff database and spills the tea about one specific position. let's get into it 🎀

✨ NAME ✨

bearoffdump — dump a position from the GNU Backgammon bearoff database 💅

🌸 SYNOPSIS 🌸

bearoffdump file id

🦋 DESCRIPTION 🦋

so bearoffdump takes two things: the path to a GNU Backgammon bearoff database and a position number, and then it dumps the bearoff info for that position. that's it. that's the whole job. she's focused, she's efficient, she's giving main character energy. ✨

you can call her on either of these two girlies:

• the one-sided bearoff database, normally /usr/share/gnubg/gnubg_os0.bd
• the two-sided bearoff database, normally /usr/share/gnubg/gnubg_ts0.bd

and the tea she serves is different depending on which one you hand her:

• for the one-sided one, the output includes the probabilities of bearing off all checkers in varying numbers of moves 🔥
• for the two-sided one, she only gives the probability of winning and the doubling cube equity 💀

ngl bestie, the id is difficult to derive if you don't know GNU Backgammon internals. like, genuinely. it's not a vibe-check situation, it's an internals situation. 😭

here's the lore tho: every possible combinatorial position of checkers and points gets assigned a position number. and then:

• id divided by that number = the player position
• id modulo that number = the opponent position

math girlies stay winning fr fr 🧮✨

also, the number of points and checkers is set when the bearoff database is built, and bearoffdump will show you both of those when you run it with any id. so even if you have no idea what you're doing, you still get a lil freebie. 🫶
