Bridge cardplay database.

[benlessard]

Lets just say that you would want to make a database of ending/squeeze positions and you want to avoid redundancy (doublon). Wich rules would you need for your database assuming you cannot use x for small cards.

 

EX

1- its always south to start.

 

2- if there is trumps its always spades. If you dont need to ruff prefer NT. For NT contract only use spades if you need all the four suits.

 

3- suits go from shortest/weakest to strong.

 

4- Always use the highest for defense and lowest cards for offense that you can afford. Between NS south has lowest spots.

 

5- only use 3 hands if possible. If you use 4 hands W has odds and Est Even cards.

 

5a- prefer RHO for squeeze working against both opps, and LHO if position is important.

 

This is simple squeeze

 

[hv=pc=n&s=sh2dac2&w=shdc&n=shd2ca3&e=shadckq]399|300[/hv]

 

Positionnal squeeze.

 

[hv=pc=n&s=shdac32&w=shadckq&n=sh2dca4&e=shdc]399|300[/hv]

 

 

Coumpond squeeze NT if i didnt make a mistake.

 

[hv=pc=n&s=s2h32d2ck2&w=shdkj9cj97&n=s3hda3ca43&e=sahdqtcqt8]399|300[/hv]

 

Do you have any suggestions ?

Some rules that shoot into my mind which probably do the trick:

- Don't use exact cards, but translate them to a common naming convention based on the order of the real cards. For example ♣32 are translated to ♣1 (lowest) and ♣2 (second lowest). If you have a similar position with only ♣86, they'll also be translated to ♣1 and ♣2. When displaying the position, you can translate them using your rule 4.

- Always use the same suits. For example: use the minors when you only have 2 suits, or use ♣-♦-♥ when you need 3 suits.

- Have a fixed rule to determine which suit is trumps (preferably ♣ since we always use that suit).

- Have a fixed order of how you fill your suits (like you did in rule 3). Strength of suits can easily be determined based on my first rule.

- When you have equal suits, use the lowest when the squeeze card is in one of them.

I published an article specifying a similar standard format for card-play diagrams in the January 2011 edition of Scottish Bridge News.
