In the game of 2-7 Triple Draw the only cards you get to see are your own. So understanding your cards, their potential, and which cards to discard is a crucial part of your success at the game.
First and foremost is to understand the hand ranking and what it takes to win! A common mistake is for beginners to forget that aces are always high in 2-7 triple draw. If you have an ace you want to get rid of it not hold on to it to go with your other low cards, A good beginner’s rule of thumb is bet money without a two also known as a deuce. All of the top for hands in 2-7 Triple Draw, that is to say the lowest ranking hands, have a deuce in them. Those hands are, from strongest to weakest, 2-3-4-5-7, 2-3-4-6-7, 2-3-5-6-7, and 2-4-5-6-7. Remember, in 2-7 Triple Draw the strongest hand is the one with the lowest ranking in poker hands. Because straights are ranked in hands a 3-4-5-6-7 would give you a straight that is most likely to be beat.
If you do have to draw cards then it is best to be drawing just one card to have a hand with a low 7 or even an 8. If you have 9 low then drawing could get you in even more trouble and you are better off standing pat especially if there is only one round left. Although your 9 can be beaten you have a higher chance of drawing an even higher card or drawing a pair than you do of drawing something lower that will improve you hand. A lot depends on what your opponents are doing. Most hands draw two cards in 2-7 Triple Draw so if you opponents are drawing more than that you can go up against them with your 9 because it seems like they are in trouble.
A card to be wary of is 6. This card can ruin your low hands by converting them into a straight. For example, if your opening hand is 4-5-6-7-k you should get rid of the 6 because otherwise you may find yourself with a straight after the draw.
Most of the hands you play you will be drawing two cards for so if you need to draw more than that you aren’t holding a reasonable hand. Even then, if you need to draw two cards you should at least be holding a deuce. Many players think that because there are three draws they have a good chance of bettering a weak hand. This is not true and doesn’t work in the long run. Like all poker games 2-7 Triple Draw is a game where you want the nuts or near nuts, that is the best possible hand right from the early rounds. If you don’t have a good hand then fold and save your chips for a hand that you can win with.
In short, tight play most of the time and aggression when you have a strong hand are the way to go with 2-7 Triple Draw.
