A 
10 10 
This flop has a lot of dangerous aspects to it. Of course there is a risk of someone having a 10. It ’s much more likely that someone has a 10 with a flop like this than it would be if someone had a 6 in a flop like A 6 6 .
If you have a flush draw with this flop, then you have to worry about making your flush with a card that makes someone else a full house.
With that in mind, a draw to a hand like J 9 is probably a much safer draw then a draw to a hand like 7 6 .
Although a Jack-high flush is better than a 7-high flush, that’s not the reason’s it’s a much better draw. It’s because the J 9 has two of the likely cards that might make a full house for someone with a 10, an important consideration.
There are similar risks to possible inside-straight draws with this flop. When a pair is on the board, the card that makes your straight not only might make someone a flush, but also might make someone a full house.
A 9 
5
This flop isn’t likely to give anyone any draws. If the pot was unraised before the flop, it’s also unlikely anyone has an Ace in some games, depending on the particular players involved, of course.
A hand like a 9 7 is likely to be the best hand with a flop like this. Of course, if any of the other players are giving any significant action, you might have to revise that estimate.
Q J 5
This flop is very likely a good one for someone. Anyone with two high cards has part of this flop, and it’s got flush draw potential for someone with two Diamonds.
This is a flop that you would want to play very aggressively if it fits your hand very well. Some hands that this flop would be excellent for would be A K , Q Q 
, K J , a K , a J , Q 10 .
Some hands that might be in some danger with this flop would be A 10 , K J , Q 10 . Note the distinction between Q 10 and Q 10 . The three-flush with the hearts can make a difference with these hands.
That’s not to say that you should automatically fold those hands that might be in some danger, but you should consider folding them if the action on the flop involves a lot of raising.
K 10 5
Again, this is a flop with a few possible draws. Possible flush draws and a possible straight draw are reflected in this flop.
J 10 7
This is another potentially scary flop. A lot of hands could have part of this flop. There is, of course, the flush draw possibility and straight draws.
Someone may already have a straight. A hand like A K is a great hand for this flop, and A K is also a pretty good hand.
The backdoor flush draw by itself isn’t a good draw, but when it’s added to the other possibilities of A K , it makes that hand all that much better.
A hand such as 10 9 is a good hand for this flop. A pair with a gutshot straight draw is usually a fairly good hand, and, again, the backdoor flush draw just makes it better.
Whenever the flop has connected cards (the J 10 ), you need to consider the possibility that someone has two-pair as those are the kind of cards most players tend to play.
This is one of those flops that you shouldn’t get involved with aggressively unless you have one of the better possible hands for it.
9 5 2
This is what’s known as a garbage flop. It’s very unlikely to have hit anyone. It has no big cards, no connected cards, and no suited cards. It’s the kind of flop that many players like to bluff with.
