Chinese Poker Help.

[JDonk]

I have recently started playing Chinese Poker and some of its variants but am ignorant of alot of its rules.

If anyone could help me with these few questions that would be great.

-is a scoop is when player 1 wins the top middle and bottom from all 3 players, so they all pay you 3+3, or is it individually as in Player 1 beats player 2 and 3 but not 4 for all 3 so player 2 and 3 pay you 3+3?

-If you surrender do you pay all players still in play 3?

-A natural is defined as having "Three Straights, Three Flushes, Six Pairs, or 13 Unique cards(a 13 card straight)"
so how do you get 3 straights or flushes, is it 4 of 3 suits? or 4 of 3 runs?

-In 2-7 Chinese we've been playing are bonuses as quads on the bottom is +1 straight flush is +2 and Trip aces up top is +1, are these common bonuses and if you have the nuts in the middle (2-7) do you typically pay +1?

-is there a free chinese poker hand calculator on the internet?

-what is a good website to find C.poker strategys and information?

thanks for your help!
