Whisting features
Semi-responsible whist. It means that for each undertrick on whist the defender is written a half of the contract value in the mountain.
For example, a 6 tricks contract was played. The declarer took seven tricks. The record will be the following.
- 2 points is written to the declarer in the pool for the made 6 tricks contract.
- The defender is written in the mountain: 1 (1 undertrick) * 1 (a half of the undertricked cost in the 6 tricks contract) = 1 points.
- The defender for 3 taken tricks writes on the declarer 3*2=6 whists.
Gentlemen's whist. If remise then the consolation and whists for the taken tricks are halved between the whisting player and passing player. The consolation in «Rostov» pool doesn’t depend on the game type and is usually equal to 10 whists for each undertrick by the declarer. The consolation is recorded to both players.
For example, a 7 tricks contract was played The declarer took five tricks. One opposing player whisted and another passed. The whisting player took five tricks accordingly. The record will be the following:
- The declarer for 2 undertrickings is written in the mountain 2*8=16 points.
- 5 actual tricks: 5*8=40 whists;
The whisting player consolation for two additional tricks: 2*10=20 whists.
The passing player consolation wil be 2*10=20 whists. In total, 20+20+20=60 whists.
The whisting player will write 60/2=30 whists on the declarer, and the passing player will also write 60/2=30 whists.
If both players whisted then the record will be made as follows:
- The declarer for 2 undertrickings will be written in the mountain 2*4=8 points.
The first whisting player. Took 3 tricks. For actual tricks: 3*4=12 whists. Consolation for 2 additional tricks: 2*10=20 whists. In total, the first whisting player will write on the declarer 12+20=32 whists.
The second whisting player. Took 2 tricks. For actual tricks: 2*4=8 whists. Consolation for two additional tricks: 2*10=20 whists. In total, the second whisting player writes on the declarer 8+20=28 whists.
As a result, 32+28=60 whists will be written on the declarer. All pass
«All pass» round is played on whists. The cost of one trick is usually 5 whists. The one who took the least tricks wins. If the least number of tricks were taken by two players, they write the whists lost by the third player half-and-half.
For example, a player W took 1 trick, player S took 4 tricks, player E took 5 tricks. In this case player W will write on a player S 4*5=20 whists, and on a player E 5*5=25 whists. Another example: each players W and S took 2 tricks, and player E – 6 tricks. Each of players W and S will write on a player E (6*5)/2=15 whists.
«All pass» round doesn't progress – even if several «All pass» rounds are played in a row the trick cost is not changed.
A declarer writes the cost of one trick in a pool if not a single trick was taken in the «All pass» round (besides whists on other players).
The talon in the «All pass» round is never open. When there are four players a player sitting on the talon writes in a pool as for zero tricks.
The game end
The game goes on till the moment until each player reaches the agreed points in the pool.
