PLO Board Texture Analysis: The Numbers for Every Flop Class
Board texture is the one variable in a PLO hand that both players share: study a texture class once and the work pays off on both sides of every pot that flops it. This article is the map: how often each texture arrives, what it does to the ranges, and how the solve bets it - with each claim linked to the reference page that holds the full table.
How often each texture arrives
Exact frequencies over all 22,100 flops: 55.1% two-tone, 39.8% rainbow, 5.2% monotone; 82.8% unpaired, 16.9% paired, 0.2% trips. Combine them and the modal PLO flop is unpaired two-tone - a flush draw available, no flush yet, everyone connected somewhere. The board probabilities reference has every class with its full runout tree; the numbers worth carrying in your head are that an unpaired flop pairs by the river 38.8% of the time, and a rainbow flop still ends flush-possible 16.8% of the time. Static boards are less static than they look.
What texture does to the ranges
Texture moves equity between ranges in patterns you can learn once. High and dry favors the preflop aggressor: on ace-high boards the 3-bettor holds 63-65% and flops top set almost one time in five. Low and connected favors whoever called: the same 3-bettor is an underdog on 7-6-5 two-tone. Middle rundowns hit both single-raised-pot ranges nearly identically (T-9-8: 49.3 vs 50.7, both sides with ~20% straight draws and ~24% flush draws), which is why those pots play honest and violent at once. The range advantage page computes this split for any of twelve curated textures plus any flop you type.
What texture does to the betting
The c-bet aggregation across all 1,755 flops turns the equity map into frequencies. After the big blind checks, the button bets 56.5% on ace-high boards against 47.9% on K/Q/J-high; 52.5% on disconnected boards against 38.5% on connected ones; 31.8% on trips boards. The donk-lead column mirrors it: the big blind leads 10.6% of flops overall but 15-18% on middle rundowns and under 3% on ace-high - texture tells you who is about to bet before anyone acts.
How to actually study this
Study textures the way the references are built: by class, not by anecdote. Learn the arrival frequencies first (they are the weights on everything else), then one texture family at a time against the range data, then check your intuitions against the betting aggregates. The trainer and the solver tool close the loop from class-level patterns back to specific boards. A player who knows what 55% of flops have in common beats a player with fifty memorized specific boards, because the first one has an answer on flop fifty-one.
