In pineapple you are dealt 3 cards (in Texas Holdem - two). Then it all goes like in Texas Holdem, the only difference is that you can leave only two cards in your hand, discarding one after the flop betting round. For example you're dealt Jh Js Jd. And the flop looks this way Jc 6s Qh.
In this situation you don't have Four of a kind... You must discard one of your jacks. Though you still have trips. Anyway, in pineapple you have better choice than in Texas Holdem. Sometimes it's more difficult for you to decide what to discard than to decide how much to bet. In Pineapple you have to evaluate the possible strenght of your hand before you could see the last two cards.
For example you have Jh Qd Kd. And the flop is Js 10d 3s. You can't wait for the turn to see what two cards to play. What are you ready to discard now? I think that a completed hand is better than any draw. So we'll leave jack... If so then there is no doubt what to discard. It will be queen. Because you want to have a king kicker.
