Board Texture

Hi,

I want to ask you, how you seperate different board textures into categories.
If I did not get it wrong theoretically, the definition is, how many cards on the next street is going to change the nuts (or a couple of strong made hands to weak hands?). I.e. monotone flops are lockdown flops. So if I have Kc7c2c any K, 7 or 2 would change the current nutflush into a non-nut hand over turns and rivers. Those are 8 cards if we assume one K is dead. So the rating would be 8 points.

If we have AsKc7h the board would be already considered not lockdown anymore but as "dry". Any Q, J or T = 9 cards (not 12 because we block 2 cards when holding the gutshot or all 3 if we have an inside wrap, but I dont want to make it too complicated) would fill a possible straight. I also take into account that all 21 non-pairing (because a pairing card would not change the nuts but lock down the board to river) flushdraw enabling cards (9s, 9c, 9h, 8s, 8c, 8h, 6s, 6c, 6h, 5s, 5c, 5h, 4s, 4c, 4h, 3s, 3c, 3h, 2s, 2c, 2h) and the remaining 5 straightdraw enabling cards (9d, 8d, 6d, 5d, 4d) could bring a change to the flopped nuts by the river. I weigh those draw-enabling cards with 0,2 which mirrors approximately the Equity given ott. So that would be 9+5,4 = 14,4 points.

The more points, the "wetter" the flop is.

If you don't like this approach, what is your way to distinguish between wet and dry? How many sub-categories like semi-wet do you have?

Re: Board Texture

Hi, may I ask what you intend to do with the classifications of flop ?

Re: Board Texture

I posted a link in the discussion. The approach he has is not the same though btw.

If I can recognize the "wetness" of a board it would help me to decide which line/ranges I have in that spot. I could link them to a gameplan that I have prepared and make it easier to know during the hand, in which range the hand I have belongs to/ which strategic options make sense.

Re: Board Texture

I would be worried that not all ranges are the same.

Some situations a player has more Ax, or more low cards, etc...and if you just treat all flops according to their predefined category I would be worried that you set yourself up for mistakes.

Re: Board Texture

You are right. Flop interaction is a factor as important as the board texuture or range by itself.

I also wrote it wrong.. it should not mean, that the board help me to play the range, but the other way round, I can take a guess, how to play different ranges on different boards.

Re: Board Texture

I've been way down this particular rabbit hole before. This is how I think about it now:

in fixed bet games where 100% flop cbetting is correct on some boards but not on others, there is a point on the spectrum of flops where (no pair no draw no showdown value) will be ev neutral as a bet or check; flops that benefit the raiser relative to this point will be said to increase the range advantage; flops that benefit the caller relative to this point will be said to decrease the range advantage. The implication is that boards that benefit the caller dictate that the bettor only bets (value hands + real draws)

in games of varying betsizes, the betsize chosen will dictate proper play by the caller(fold more vs big bets, continue more vs small bets). There is a point on the spectrum of flops where (the least profitable draw that is bet) is ev neutral as a bet or check(a value greater than zero on the flop) for the preflop raiser. Flops that benefit the raiser relative to this point will be said to increase the range advantage. Flops that benefit the caller relative to this point will be said to decrease the range advantage. This point is directly affected by betsize which is a function of the value range chosen(there is a point of diminishing returns as you add value hands and increase betsize). When this point of (value range saturation) and (betsize maximization) is met, the profitability of the value range will be maximized as will the potential range of draws we may bet be maximized.

This is why I think the next step for no limit holdem theory is to define board texture by betsize and where the ev is coming from(protection, draw value, unimproved showdown value). I'm just not sure what the definitions will look like.
