Flopzilla is a poker calculator that has been designed to let you quickly and easily figure out how a range hits a board. Just enter a preflop range and a board and Flopzilla will work out for you how often that range hits hands like top pair, middle pair, a flushdraw, a gutshot, etc. Far too many players ignore flop texture when playing Texas hold’em. Why so many players ignore texture continues to amaze me. After all, a flop’s texture is free information when you’re trying to connect the dots by evaluating the board’s composition in conjunction with the range of cards your opponent could be holding.

In the post Flop texture I discussed one view of flop texture, which is to divide flops into dry boards or wet boards, dependent on the composition of the three cards. In this post, I shall discuss another approach, which concentrates on suitedness and connectedness. In this post, I will be referring to the groups in Hand Rankings and Strengths.

It is almost a truism to say that previously strong pre-flop pocket cards can turn into a mediocre or trash combination dependent on the flop, and previously mediocre or possibly trash pocket cards can be transformed into strong or even monster hands dependent on the flop. Since we are considering playing online poker, and hands move at a fast clip, we need a way to quickly evaluate the flop, to determine whether or not to fold, or to continue to bet on the turn, the river, and eventually to participate in the showdown.

Firstly, we ask how many cards of the same suit does the board have. Is a flush draw possible? There is a better chance if all three cards are of the same suit; if you have two cards of a matching suit you have a made flush, if you have one card of a matching suit, you need only match on the turn or the river to turn the hand into a made flush. If there are two cards of the same suit, and you have one or two cards of a matching suit, then help from the turn or river is required, but it’s possible to turn your hand into a made flush.

Next, we ask how many connected cards does the board have. If the three cards are all connected there is a good chance of a straight draw, and you might even have a made straight draw with your own pocket cards. If two cards are connected and there is a one-gap or two-gap in the other card, you may need only one matching card, and assistance from the turn or the river to make a made straight draw.

Finally, we ask how many face cards does the board have, and how many pairs, preferably high pairs there are. If you are playing a disciplined game, and restricting your pocket cards to Groups 1 to 3 in early position, and Groups 4 and 5 in late position, face cards in the flop are more attractive because most players will play through to the flop holding face cards, in the hopes of making a two pair, a trip, a full house, or even four of a kind.

Rainbow flops

By way of definition, a rainbow flop is a flop where all cards are of a different suit, so no flush draws are possible. If you have two suited matching cards, then a backdoor flush draw, with help from the turn and the river have a very low probability of occurring.

Most rainbow flops are where there is one high card, or where the flop is all rags, which are cards with a denomination of 8 and under. An example of a rainbow flop with one high card is:

With this flop, the best pocket cards are K9s (a Group 6 hand, so really only playable through to the flop in late position) making a two pair, or any King with a high kicker for a top pair.

Another rainbow flop, which is all rags, is:

2-suited flops

A 2-suited flop contains two cards of the same suit. For example:

Come December 2019, a new casino with all the bling of Las Vegas will open along Interstate 5. That’s the assessment of the Puyallup Tribe as it builds its new $370 million Emerald Queen Casino. Emerald queen casino construction updates.

A flush draw, which means you if have a Group 2 A ♢ J ♢ or Group 4 T ♢ 9 ♢, you have a good chance to make a flush draw on the turn or the river, and should bet through to the showdown. A single high-value matching card, such as A ♢, or K ♢, might lead to a back door flush draw, but would need a matching ? ♢ on both turn and river, which is a low probability outcome.

3-suited flops

A 3-suited flop is where all the cards are of the same suit. For example:

If you have two matching pocket cards, such as Group 3 Q ♢ J ♢ or A ♢ 10 ♢, you effectively have the nut flush and should play aggressively all the way to the showdown, because you are hardly likely to be beaten. However, you need to beware Group 6 K9s or K9 because a K or 9 on the turn and the river will make a full house. This is an unlikely, but possible, outcome and needs to be accounted for.

2-connected flops

This type of flop makes it possible to make a straight draw, and because players prefer to play connected pocket pairs, and a two pair is also more likely. For example:

This is a rainbow flop and an open-ended straight draw is possible, with a one in three chance of a straight. So a Group 4 KQ requires an A or 9 to make a straight on the turn or the river, and a Group 4 98s requires a Q or a 7 on the turn or river to make a straight draw.

3-connected flops

A 3-connected flop makes it possible for a player to have a made straight. For example:

Here, a Group 2 KQs or a Group 4 KQ are required to have a made straight, but note also, a Group 5 87s or Group 8 87. The danger of playing the lower end pocket cards is you might be outplayed by the high-end pocket cards. It’s also possible to play Group 1 QQ or Group 4 88 and rely on the turn or river cards to make a straight.

High pair flops

A dangerous flop is a high pair flop. Most players will bet through to the flop on high pocket cards. For example:

A Group 1 JJs will result in four of a kind, a Group 3 KJs will result in a full house, a Group 2 KQs or Group 4 KQ will result in a two pair. The danger with playing a high pair is other players, playing through to the flop with their high pocket cards, may outplay you despite holding strong pocket cards yourself. Dangerous territory, indeed.

Low pair flops

The danger for a playing encountering a low pair flop is from other loose aggressive or loose passive players. For example:

it is likely that a tight aggressive player will fold any hand containing a 4. But loose players might likely play a hand containing a 4 for a trip, or a 9 for a two pair. However, any top pair is a viable combination for a two pair or full house, with assistance from the turn or the river.

High cards only

Where there are high cards only, such as:

invites participation from a player playing Group 1 to Group 3 hands. Caution must be exercised because other players playing to the flop may have similarly strong hands, so it is necessary to observe other players’ betting patterns to determine whether to continue. So a Group 3 QJs or Group 5 QJ will be a straight, a Group 1 AA or KK, Group 2 TT will be a trip. Other winning combinations will be possible with assistance from the turn or river, but that’s another story.
