Stack-to-pot ratio
How committed are you?
The SPR — effective stack divided by the pot — tells you, before you act, which hands can play for stacks and which cannot. Read it on the flop and you stop committing by accident.
The idea
Plan the hand before you are in it.
A low SPR means a single pair can commit you; a high SPR means only big hands want to play for stacks. Knowing the number on the flop is what stops the most expensive mistake in poker — getting all-in by accident with a hand that cannot take it.

Mid SPR
With an SPR of 4 to 6 you need a solid hand — two pair, a set — to play for stacks comfortably. Top pairs lose value: be careful not to fall in love with them.
The SPR is read on the flop, before you act: it defines which hands can play for stacks and which cannot. Planning the hand by its SPR avoids the most expensive mistake in poker — getting committed by accident with a hand that cannot take the heat.
