Sit and Go heads up play when the blinds are big

[McGrain]

Any tips?

I find this very tough as the usual rules I try to play by when heads up (small bets, avoid speculative all in play, raise or fold) seem to go by the by in favour of random pushing.

This is because the blinds are so big - I make an information raise, he goes all in and I can't call according to my usual heads up rules.

I've adjusted to this pretty quickly, but my win rate when I get heads up Sit and Go is exactly 50/50.

I'm pretty new to this form of poker, but i've been playing cash games and tournaments all year.

So any Sit and Go heads up specific advice would be gratefully received.

Thanks for reading.
