Range Blitz
A seat, a hand, one second: is it a standard open? Answer in or out, ten times, against the clock. Builds instant range recognition.
From , would you open this hand?
How to play
Read the seat + hand. A position and a single starting hand appear.
In or out? Decide if it's a standard raise-first-in from that seat.
Beat the clock. Ten questions; your total time is scored too.
Speed comes from knowing the shapes: every pair, most suited aces and broadways, and — from later seats — suited connectors and offsuit broadways. Here's a tight early-position range to anchor on:
Why fast recognition wins
Reaching for a chart mid-hand is slow and tells observant opponents you're unsure. Drilling in-or-out calls until they're automatic means your preflop decisions cost you no time or tells, and you can spend your focus on the streets that actually decide the pot. Build the full ranges hand by hand in the Range Trainer, and study the theory in preflop & ranges.
Frequently asked questions
What is Range Blitz?
A fast ten-question quiz: you're shown a seat and a single starting hand, and you snap-answer whether that hand is in the standard opening range for that seat. It drills instant range recognition under time pressure.
How is 'in range' decided?
Against the widely-taught 6-max opening ranges — under the gun through the small blind. A hand is 'in' if a solid default strategy would raise it first-in from that seat.
Why train recognition speed?
At the table you have seconds to act. Knowing at a glance whether a hand is a standard open — without thinking through a chart — frees your attention for the harder postflop decisions.
Are these exact solver ranges?
No — they're standard 'GTO-based' reference ranges, ideal for learning. A solver would fine-tune them for exact stacks and opponents.
