About these preflop charts
These are solver-generated preflop ranges, not a rule of thumb someone wrote down. Each grid is the 169 distinct starting hands with the equilibrium action for every one of them, at the exact game type, table size, stack depth and seat you have selected — opening ranges, defending and 3-betting ranges, and push/fold charts once the stack is short enough that there is no postflop play left.
A partially coloured cell is a mixed strategy and means what it says: the equilibrium takes that action that fraction of the time. It is not the chart hedging. Mixing is how a range stays balanced, and reading a 60/40 cell as "raise" is a much smaller error than reading it as "unclear".
Every chart here is free and needs no account. Preflop is the one street you play in every hand and the only one whose solution is simple enough to hold in your head, which makes it by a distance the best return on study time available.
Holding it in your head is the part a chart cannot do for you. Reading a grid builds recognition; a hand at a table demands recall, under a clock, with the chart shut — and the gap between the two is where the money actually goes. That is what the trainer is for: it deals the seat and the depth you are looking at right now, asks for the decision without the grid in front of you, and grades it against this same solve. Two of its seven chapters have no fixed content at all and are built from the hands you have misplayed, so the charts you are worst at are the ones you get dealt most.
Frequently asked questions
Are these preflop charts free?
Yes, entirely. Every chart — every game type, table size, stack depth and seat — is available to anybody who opens the page, with no account and no payment.
What do the colours in a preflop chart mean?
Each colour is an action — raise, call or fold — and a cell split between two colours is a mixed strategy: the equilibrium takes each action that share of the time. A cell shown as 60% raise means raise that hand roughly six times in ten.
Which chart should I learn first?
Button opening and big blind defence, in that order. The button is the widest opening range in poker and the seat where a chart alone earns money; the big blind is the position you play most often and the range most people underplay by the widest margin.
Do these charts work for tournaments and cash?
Both, and they are different charts. Select the game type and the effective stack: tournament ranges at 40bb and below behave very differently from a 100bb cash game, and push/fold charts take over entirely under about 15 big blinds.
How do I actually memorise a preflop chart?
Learn the boundaries rather than the cells — which suited ace, which offsuit broadway, how far down the pairs — which is four or five facts per position instead of 169. Then test yourself under time pressure, because reading a grid builds recognition and a table demands recall, and those are different things.
Can I train these charts instead of just reading them?
Yes, and that is the point of the rest of the site. The trainer deals the spot at the game type, table size, stack depth and seat you choose, asks for the decision with no grid on screen, and grades it against this same solved range with the EV cost of a mistake in big blinds. Chapters 1 and 2 need a free account and no card, and both are graded in full — the charts stay free either way, with no account at all.
