F090 — Horse Name Nicknames

​
Business Rule

In HedgeEm v7 (horse race skin), each poker hand is represented as a horse. The horse’s name is the industry-standard poker nickname for that starting hand combination. For example, a hand of Ace-Ace is called “Pocket Rockets”, King-King is “Cowboys”, and the notoriously weak 7-2 offsuit is known as “Beer Hand”. Where an established nickname exists (per Wikipedia’s List of poker playing card nicknames), that name is used. Where no standard nickname exists, a racing-appropriate invented name fills the gap. Version applicability: V7 only. JS, TypeScript (v6), and UMA use generic hand labels.

​
Technical Design

​
Input

A 4-character hand string from GameRecord.hands[], e.g.:
  • "AcKd" — Ace of clubs, King of diamonds
  • "7c2d" — Seven of clubs, Two of diamonds
  • "AcAd" — Ace of clubs, Ace of diamonds (pair)

​
Output

A string horse name, e.g. "Big Slick", "Beer Hand", "Pocket Rockets".

​
Algorithm

  1. Parse rank1 = hand[0], suit1 = hand[1], rank2 = hand[2], suit2 = hand[3]
  2. If rank1 === rank2: key = rank1 + rank2 (pair, e.g. "AA")
  3. If rank1 !== rank2:
    • Determine higher/lower rank using RANK_ORDER
    • suited = (suit1 === suit2)
    • key = higherRank + lowerRank + ('s' | 'o') (e.g. "AKs", "72o")
  4. Look up key in HORSE_NAMES table; return fallback if missing

Acceptance Criteria

AC1: getHorseName("AcAd") returns "Pocket Rockets" AC2: getHorseName("KcKd") returns "Cowboys" AC3: getHorseName("7c2d") returns "Beer Hand" (72 offsuit — worst hand in poker) AC4: getHorseName("AcKc") returns "Big Slick" (AK suited) AC5: getHorseName("AcKd") returns "Walking Back to Houston" (AK offsuit) AC6: All 169 hand combinations return a non-empty string AC7: Function handles both card orderings (e.g. "KdAc" same as "AcKd") AC8: Horse name rendered in the CardLanePanel label for each lane
