Champion Austria (Sebastian Holzer) First hand probabilities Since there are no options for which card to play when a player is only holding one card, there is a statistically correct bid for any given card. This only truly applies if a player has the lead, and thus no information from other bids. Since a correct bid of 1 yields 30 points, and a correct bid of 0 only yields 20, a bid of 1 over time yields more points as long as the player has at least a 42.86% chance of winning the trick. The known cards are only a player's own card and the turn up, so with 58 unknowns, the odds that a hand will win in a three player game are calculated by the odds that both of the other hands lose to that player. That is, (x/58)*((x-1)/57), x=# of cards the player can beat. The calculation is similar for more players. Solving for x to yield 0.4286 or greater gives the minimum number of cards a player needs to be ahead of to justify a bid of 1. With the lead: In a 3-person game, x=39, bid 1 with an offsuit Jack or stronger. In a 4-person game, x=44, bid 1 with the 3 of trump or stronger, (4 of trump if the turn up is the 2 or 3). In a 5-person game, x=49, bid 1 with the 9 of trump or better, (the 8 will do if the turn up is higher than the 8) In a 6-person game, x=50, bid 1 with the 10 of trump or better (9 if turn-up is 10 or higher) In the special case that a jester turns up and there is therefore no trump, and the player has the lead: always bid 1 in a 3 player game, With 4 - bid 1 on 3 or higher, with 5 - bid 1 with any 9 or higher, and with 6 players a 10 or higher.
