the declarer side are allowed to participate in bidding. The trick-taking play occurs after this second bidding round. In addition to the Vint-style scoring, the declarer side gets a bonus for a made contract that depends on the level of the contract. In Skruuvi, the non-declarer side may also double by knocking on the table before the card play starts. It is also possible to bid misääri, a contract where the aim is to avoid tricks. In a round-pass situation a forced misääri is played. Since the exchange of cards favours the declarer side, final contracts in Skruuvi are rather high, at a level of four or higher. In some circles undoubled contracts of four odd tricks, and sometimes also undoubled contracts of five odd tricks, are judged made without playing out the hand. After a rubber has been played in Skruuvi, four end games (called Kotka) are played without a kitty. In the end games the bidding starts at a level of six (small slam level), and the exchange of cards favours highly the declarer side. A typical skruuvi night consists of three matches, where a match consists of a rubber of ordinary skruuvi and four kotkas. Between the matches, the seats are changed so that everyone plays as a partner of everyone else. The partnerships may be temporarily broken if the players make certain special bids, bolshevik or mussolini. In these contracts the declarer plays alone against everyone else, in bolshevik a grand slam misääri, and in mussolini a grand slam no trump. Later developments The scoring system of the classical Skruuvi, as played in the first half of the 20th century, was notoriously complicated, with scoring for games, made contracts, taken tricks (or avoided tricks in misääri), various honours, penalties for failed contracts, penalties for aces taken in tricks during a misääri contract and, of course, special scoring for bolshevik and mussolini. Since the 1950s, at Helsingin Suomalainen Klubi, the scoring system has been streamlined. Bonuses for honors and the concept of playing a rubber have been dropped altogether. A match consists of four hands of ordinary skruuvi, four hands of kotkas and four hands of bolsheviks. According to earlier rules, it was possible to bid a bolshevik, but the club rules made it mandatory for everyone to bid bolshevik once during a twelve-hand match. Only slam contracts and doubled contracts are actually played out, and other
