It depends on a lot of factors for me. In a tournament it's important for me: at what stage I find myself, how far up to the prizes, whether I'm lucky with the cards, whether I'm ready for risk, what rivals are at the table?
In the cach I'm more interested in what situation I'm currently in. If I have downstreaк, I play tight; if I have a upstreak - I can take risks more often.
And yes, I hope for the best until the last card on the river. Although the results show that I'm not particularly lucky.
