Truco - Baixada

Everything the lab shows fits on one line — the HAND field. Score, turn-up, a drafted hand, the walked history: the line and the lab stay in step both ways, and it lives in the page URL, so a spot you write down is a spot you can share, bookmark, or paste back later.

§ 1

Whole histories

A history is written in the order actions happen. / marks a completed round, * hides a card, and a accepts a raise or the hand of eleven when one is pending.

The score

leader × dealer, up to 11 each — here both sides sit at 10.

The turn-up

v4: the turn-up’s rank is 4, so the 5s are the manilhas.

Whose hand

pe[…] drafts the dealer’s cards; mao[…], the leader’s. A ! pins the hand for the whole walk.

The drafted hand

exactly three slots, strongest first: 5d is the 5♦ manilha, 3 a plain three, ? a slot left unknown.

The colon

everything after : is the played history, action by action.

A card played

a bare rank: off the manilhas, suits don’t matter, so 3 is any three.

The answer

pé answers with a jack. Two cards down — that completes the round.

A round mark

/ asserts a round ended right there. Optional — the lab writes it for readability and checks it lands on a real boundary.

A raise

r calls truco. The later rungs are r6, r9, r12.

Accept / fold

a accepts a pending raise (or the hand of eleven); f folds it.

Hover or tap any token of the line.

Manilhas always name their suit — 5d 5s 5h 5c under turn-up 4 — or, turn-up-independently: md ms mh mc.
A * after a card plays it face down: k*.
Raise rungs: r → worth 3, then r6, r9, r12.
a answers a pending raise or the hand of eleven; with nothing pending it’s just the ace.

Plate III One legal study line, token by token. The same grammar drives the HAND field and the page URL.

Pinned dealer range10x10 v4 pe![5d 3 ?] : 3 j / r a

At 10–10 with turn-up 4, the dealer is pinned to 5♦, 3, and one unknown card. The first round ends after 3 and J; then truco is called and accepted.

Hand of eleven11x8 v4 mao![5d 3 ?] : a 5d 7 / 3* j

At 11–8 the leader must first accept or fold; this line writes the explicit accept. It then shows a 5♦ lead, a completed round, and a face-down 3.

§ 2

The grammar

Read the line as a small sentence: name the score and turn-up, optionally draft either role’s cards, then put the played history after :. Square brackets always hold three cards, strongest first.

abstract grammarspot

spot: [score] [vira] [draft] : [history]
The score, turn-up, drafts, and history are optional sections of one state. A bare colon clears only the history.
draft: role [ ! ] [ card card card ]
Use mao for the leader and pe for the dealer. ! keeps that hand pinned while you walk the line.
card: plain-rank | manilha-rank+suit | m+suit | ?
Plain ranks need no suit. A manilha must name its suit, or use md / ms / mh / mc. ? (or .) leaves a slot unknown.
history: action action / action …
Actions run left to right. / is optional, but when written it must follow the second card of a completed round.
action: card [ * ] | r | r6 | r9 | r12 | a | f
A card can end in * to play face down. r starts truco; later rungs are r6, r9, and r12. a and f answer a pending decision.

VII The notation is a language for describing one exact study state. Brackets and the colon make its boundaries easy to scan.

§ 3

Read it, then write it

Try the two checks below. The lab checks the same grammar as you type and says exactly what it couldn’t read; omitted sections simply keep their current state.

two quick checks

What does this draft say?

mao![5d 3 ?]

Write the same draft

Write a pinned leader hand containing 5♦, 3, and one unknown slot. Spacing is optional.
