VI. Calling Tichu
1. You should Not call Tichu before passing.
You are giving both your opponent’s information they can use against you in the pass, and in the first hand, if they have the one/Mahjong.
It is generally not worth getting one good card from your partner, verses alerting both of your opponents in advance.
Your partner will support you when you call Tichu at the appropriate time.
You will also know if you partner can support you based on what card they past you if you follow the partner appropriate passing conventions suggested previously.
2. You should not call Tichu until, just Before, you play your first card OR your first hand.
Remember that you can pass and wait to see what happens for up to several hands, before deciding to jump in to play, and then call Tichu at the appropriate time. If a few high cards have been played, like Aces, Dragon or Phoenix,
Now those cards can no longer be used against you, when you play.
3. You need to take some risk in Tichu. If you make your Tichu call every time, you are not calling enough.
There is always a chance that your opponents will have a bomb (or two) that could stop your Tichu call. However, you should NOT take this into consideration when calling Tichu. Otherwise, you will lose too many opportunities to make a Tichu call.
4. Guaranteed (Highly Likely) leads. These can be counted on as highly likely to get you the lead.
a) 4 aces, b) Phoenix, c) Dragon, d) bomb, e) 4 or more consecutive pairs, f) long straights of 7 or more cards.
g) six or more face cards in your hand.
5. If you have four-4 or more of these “guaranteed leads” you need to call Tichu, period.
6. If you have three-3 of these “guaranteed leads” you should heavily consider calling Tichu.
7. If you have two of these "guaranteed leads”, it could be a bit risky to call Tichu. However, it depends on the other cards in your hand and/or if you know that your partner can help you get your Tichu.
8. Also considering how many singles cards (that do not form other hands) that are valued from two to ten in your hand is a factor in calling Tichu as well. For example: Two guaranteed leads may not help you, if you have four or more low single cards to get rid of.
9. When to play over a trick:
If your partner has called Tichu, you should generally be passing on tricks when your parter has played a hand. The exceptions are when singles are led and you have the chance to play a low/mid single. You are going to avoid playing high cards on single tricks, because you may deny your partner the chance to shed a mid/high single. It is a frequent occurrence for new and novice experienced players dropping J/Q/K on their partner's single trick, which can potentially wreck their partner’s Tichu hand.
10. If your partner has called Tichu, it is generally ok to play over them, with a single card, or a pair, when the cards are valued at 7-seven or under. Otherwise, you should not play higher than your partner. Please be careful, you generally do not want to play over them more than once.
11. If your partner has called Tichu, but passes on a play, it may be a sign that they need your help.
When your partner has called Tichu, if you see them passing consistently on singles/pairs/etc. then you know that they cannot; or for good reason, do not want to play, on that type of hand.
-In this case, you should heavily consider trying to win that trick, so that when you win the trick, you can now lead with a different type of hand to get your partner back into play. See options below under #12.
12. If you get the lead, when your partner has called Tichu, your goal is to give them back the lead.
-Option A. If you have the Dog, you should play it.
-Option B. Usually the next best way to give your partner the lead is to play a low single card.
-Option C. If you have really great hand to play, that you may not be able to play otherwise later, (for example three or four consecutive pairs or a long straight), and you know that will get the lead back, it may be ok to play that hand first, then follow option A or B above.
-Option D. Play a very low pair with cards valued at five-5 or less.
