Jacks or Better Question

I haven't played video poker in about 7 years. I got the chance to play it at Vernon Downs in Upstate NY this week and realized I forgot some of the correct plays.

If I get a J,Q,K, or A, just one of them and a small pair, what is the correct play? Do I keep the small pair and the jack or better card, just the jack or better, or just the small pair?

If I get a J,Q,K, or A, just one of them and three to a flush, what is the correct play if the J,Q,K or A are not part of the flush suit?

If I get a paying pair (J,Q,K or A) and another J,Q,K or A, do I just keep the pair and pull three new cards?

Thanks.

To answer your questions:

1) Keep the low pair and draw 3 cards. You always keep a low pair over non-paying high cards except in 3 cases: a) 3 or 4 to the Royal Flush b) 4 to a flush c) the specific hand 10,10,J,Q,K

2) This one is complicated, you hold a high card over 3 to a flush but not always 3 to a straight flush. It depends on how many possible ways to make a straight flush there are. If there are two or more ways to make a straight flush then you keep it, otherwise the high card. For example '567' and '568' are more valuable than a single high card but '569' is not.

3) Yes, keep the high pair and draw 3. It increases your chances of getting 3OAK or 4OAK.
