'''The interpretation of a 4 clue is not clear to all players''' | |||
{{hg|3|c=}} can play on its own given enough context (negative multi is enough here), so even after {{hg|3|c=}} plays, a 4 clue on its own will lead to a save misinterpretation if the receiver does not have one of the following context: | |||
:a) all critical 4 ({{hr|4}} and {{hg|4}}) are visible | |||
:b) negative critical colour ({{card|r|color={{w}}|background={{r}}}} and {{card|g|color={{w}}|background={{g}}}}) | |||
:c) negative critical chop (i.e. while {{hr|4}} and {{hg|4}} were discarded, the chop card was not saved) | |||
Notice how: | |||
:a) depends on information in other hands which is hidden from at least one player. | |||
:b) and c) depend on information in the same hand which is available to all players. | |||
If all the critical 4s were playable, the receiver will play their rightmost 4 as {{hr|4}} / {{hg|4}} and after {{hw|4}} plays, they understand the 4 clue was not a save and in fact a left-focused play clue and go on to play their left 4 too as a bonus. | |||
The problem in this game is that {{hr|4}} is not playable so the team cannot wait to give a clear play clue due to {{hm|5}} on chop. | |||
So every player is unsure if an extra clue is required to avoid {{hm|5}} discard because they could hold {{hr|4}} which would make ({{hw|4}} and) {{hg|4}} play. | |||
'''The interpretation of a green clue is clear to all players''' | |||
Since a 4 clue on its own may or may not be enough to play {{hg|4}}, colour takes away the save interpretation entirely and simplifies the thought process of every player. | |||
Every player understands that MrGrogu must prevent {{hm|5}} bombing as {{hg|4}} (or {{hm|2}}) now. | |||
If MrGrogu decided a fix clue is required but discards assuming Kaznaka will save {{cardholder|{{hm|1}}{{hy|5|n=}}{{hb|3}}{{hr|5|n=}} |Feen 🡲}} | |||
, this would be a blunder since MrGrogu's hand (e.g. {{cardholder|{{hk}}{{hr|3}}{{hw|5}}{{hk|1}} |MrGrogu 🡲}}) could require Feen to begin a triple save and Kaznaka would be free to bomb {{hm|5|{{g}}|c=}}. | |||

Interpretation
Extraction
Forum post | 2026-07-02
- Tyrion to Kaznaka: these 2 cards are green.
The interpretation of a 4 clue is not clear to all players
green3,with a green clue, can play on its own given enough context (negative multi is enough here), so even after green3,with a green clue, plays, a 4 clue on its own will lead to a save misinterpretation if the receiver does not have one of the following context:
- a) all critical 4 (red4 and green4) are visible
- b) negative critical colour (r and g)
- c) negative critical chop (i.e. while red4 and green4 were discarded, the chop card was not saved)
Notice how:
- a) depends on information in other hands which is hidden from at least one player.
- b) and c) depend on information in the same hand which is available to all players.
If all the critical 4s were playable, the receiver will play their rightmost 4 as red4 / green4 and after white4 plays, they understand the 4 clue was not a save and in fact a left-focused play clue and go on to play their left 4 too as a bonus.
The problem in this game is that red4 is not playable so the team cannot wait to give a clear play clue due to multicolour5 on chop.
So every player is unsure if an extra clue is required to avoid multicolour5 discard because they could hold red4 which would make (white4 and) green4 play.
The interpretation of a green clue is clear to all players
Since a 4 clue on its own may or may not be enough to play green4, colour takes away the save interpretation entirely and simplifies the thought process of every player.
Every player understands that MrGrogu must prevent multicolour5 bombing as green4 (or multicolour2) now. If MrGrogu decided a fix clue is required but discards assuming Kaznaka will save multicolour1yellow5,with a 5clue,blue3red5,with a 5clue, Feen 🡲 , this would be a blunder since MrGrogu's hand (e.g. black powderred3white5black powder1 MrGrogu 🡲) could require Feen to begin a triple save and Kaznaka would be free to bomb multicolour5,with a multicolour clue,.
From MrGrogu pov
Either must play for multicolour2 multicolour3 multicolour4 or give a fix for green4 now.
Context of g (or w) clue:
- Fix multicolour5,with a multicolour clue,green4,with a green 4clue,yellow4,with a 4clue,white4,with a 4clue, Kaznaka 🡲 = 0 blind plays
- Play multicolour2 multicolour3 multicolour4 = 3 blind plays
Convention is the fewest number of blind plays from your hand is the correct interpretation.
Imagine instead of multicolour5,with a multicolour clue,green4,with a green clue,yellow4white4 Kaznaka 🡲 we had multicolour5,with a multicolour clue,green4yellow4,with a yellow clue,white4 Kaznaka 🡲.
Context of y clue:
- Play yellow3 + fix multicolour5,with a multicolour clue,green4,with a 4clue,yellow4,with a yellow 4clue,white4,with a 4clue, Kaznaka 🡲 = 1 blind play
- Play multicolour2 multicolour3 multicolour4 = 3 blind plays
We all agree that a y clue clearly demands a blind play.
Hypothetically if MrGrogu played a yellow3, what would MrGrogu do next round? Go on to play for multicolour2 multicolour3 multicolour4 or give a fix multicolour5,with a multicolour clue,green4,with a 4clue,yellow4,with a yellow 4clue,white4,with a 4clue, Kaznaka 🡲?
Why should the question of giving a fix on g+4 be any different to y+4?
For a multicolour2 multicolour3 multicolour4 finesse, the best clue choices would be multicolour5,with a 5clue,green4yellow4white4 Kaznaka 🡲 / multicolour5,with a multicolour clue,green4yellow4white4 Kaznaka 🡲 / multicolour5,with a multicolour clue,green4yellow4white4 Kaznaka 🡲.
The timing of the clue is good
From the clue-giver's point of view:
- apart from MrGrogu's hand every card they see is either trash or 5
- any of their cards could be non-trash, so it makes sense to give a clue and encourage all non-busy players to discard.
Because the timing of g clue (rather than discard) is otherwise unnecessary as has been pointed out, giving the clue now communicates to all other players more subtle information:
- there are no non-trash cards that we can't guarantee marking
- my hand (also mostly trash as it turns out) is more important than the cards I see
The benefits if we agree that MrGrogu must give a fix clue:
- their playable black powder5 remains in finesse position while other hands draw new potential bluff targets
- the discard of the only other useful card in any hand (black powder2) is delayed
Prompt + Layered finesse
Forum post | 2026-01-01
- Alice to Cathy: these 2 cards are yellow.
redyellowgreenbluewhite white1yellow2red4yellow1,with a 1clue, Bob 🡲 green4blue4yellow3,with a yellow clue,yellow5,with a yellow clue, Cathy 🡲
- Bob plays yellow1,with a 1clue,.
- Cathy sees yellow2 is layered behind a playable white1, so she could hold yellow3.
- Cathy discards to see if Bob tries to play yellow2 next turn.

redyellow1greenbluewhite white2white1yellow2red4 Bob 🡲 white3,with a white clue,green4yellow3,with a yellow clue,yellow5,with a yellow clue, Cathy 🡲
- Bob acknowledges the white clue and continues to look for yellow2 because white1 can be inside the yellow2 layered finesse.
- Cathy sees a playable white2 in Bob's hand, so she could hold white3.
- Bob blind plays his 2nd slot for yellow2 and white1 successfully plays.
- Cathy and Alice discard.
- Bob blind plays his 3rd slot yellow2.
- Cathy plays yellow3,with a yellow clue,.

redyellow3greenbluewhite1 green1blue4white2red4 Bob 🡲 red2,with a red clue,white3,with a white clue,green4yellow5,with a yellow clue, Cathy 🡲
- Since Bob knows the white clue is a layered finesse, he must keep looking for white2 before he can start looking for red1 because red1 can be inside the white2 layered finesse:
black powderblack powderred1white2 Bob 🡲
- So Alice cannot bluff a player who is already in the middle of responding to a finesse if it can be layered.
- Bob knows the white clue cannot be a bluff because Cathy would not discard unless she sees a playable white2 in Bob's hand.
- So Bob knows he is promised white2 and keeps playing each slot from his now 3rd slot left to right until his white2 is played.
Finesse + Promise Bluff
Alice's view | Donald's view | 2024-08-02
Example with a player (Bob) between the clue giver (Alice) and first response (Cathy):
- Alice clues yellow4,with a yellow clue,
- Bob does something unrelated
- Cathy plays yellow1
- Donald plays black powder3 as yellow2
- Emily now has yellow3 marked in their slot 1
Q: Why isn't it a layered finesse? (i.e. must keep playing cards until they find yellow2 ?)
- This question reveals a misunderstanding of bluffs. A better question would be:
Q: Will anyone else try to play yellow2 after black powder3 plays as yellow2 ?
Early Game Color Trash Bluff
Alice's view | 2026-09-09
Bob's blind play reveals that multicolour1,with a multicolour clue, is not playable, so Cathy understands that she must hold multicolour1,with a 1clue,.
Emily knows that if multicolour1,with a multicolour clue, were any non-trash card, all blind plays must wait for Cathy's multicolour1,with a 1clue, or red1,with a 1clue,.
