Heads up SnG: good ways to finish off an opponent?

when i have about 4-1 chip advantage i look to finish off an opponent in a single hand.

what are good ways to finish them off 1)when blinds are low and 2)when blinds are high.

You have to give them a walk more often because they will be shipping over steals more often.

is it wise to loosen up the all in range?

it breaks my heart to keep folding the button when the blinds are big. is it a good idea to loosen the shoving range and shove them in position? like Q-7o +?

sometimes i fold too much, then wait for a hand like A-10+, then lose.

use Nash equilibrium push/fold charts.

Link this chart? Would really likes to see it

Looks like BS I would not click the link above, leads to a bunch of bogus sites...

if by bogus you mean mostly 2+2 threads, then yes.

Interesting system I need to learn this and apply it and see the results for myself

nash only works if the other player uses nash too

basically it is a system that allows you to break even (play perfect poker) when your opponent plays perfect game, aka plays by the nash graph.

but since your opponent won't use the nash graph you have to adapt accordingly.

that said it does not mean nash can't help you improve your game. the link is good and those threads that come up can really be helpful.
