How It Works

Pick your cards, set the stacks, and the calculator does the math. Here's what each number means.

Stack-to-Pot Ratio (SPR)

SPR is your effective stack divided by the pot. It tells you how deep you are relative to what's already in the middle — lower SPR means more of your stack is committed.

Commit
0–4
Marginal
4–8
Cautious
8–15
Deep
15–25
Very Deep
25+
Shallow (more committed) Deep (more flexible)

Equity vs Villain

Assign villain specific cards for exact equity, or click their avatar to set a range for Monte Carlo equity. The tool calculates how often you win this matchup across all possible runouts.

Pot Odds

The price the pot is offering you. If you need to call $50 into a $200 pot, you're investing 20% of the final pot. Your equity needs to exceed this price for a profitable call.

Implied Odds

When direct pot odds fall short, implied odds measure how much more you need to win on later streets. Deeper stacks and nut draws improve implied odds — villain is more likely to pay off a big hand.

Draw Quality

Not all draws are equal. A nut flush draw (holding the ace) has clean outs and strong implied odds. A non-nut flush draw risks making a second-best hand — that's reverse implied odds.

Board Texture

Dry boards (rainbow, unconnected) produce fewer draws and more stable hand values. Wet boards (suited, connected) create many drawing possibilities and make hand values volatile across streets.
