CallBreak is an Indian variant of Spades, The rules differences from normal Spades are:
- Solo (no partnerships)
- Possible bids are from 1 to 8 (no Nil bids)
- Players must play a stronger card than the current trick winner, if able.
- Can lead first trick with a spade (No “spades broken” rule).
- No bags penalty.
- Game ends after 5 rounds.
My question is, what is a strong open lead in CallBreak?
While this question could be seen as opinion based, it is not so since I have access to a simulator of the game which allows me to compare clones of the same AI-agent that differ solely in the open lead, thus finding which open lead is better.
It is available to play in many mobile game applications and also at http://callbreak.com/.
