Answer — Check carefully the vulnerability!
The vulnerability is really important in helping you to decide your strategy e.g. if you are non-vulnerable at favourable or even equal vulnerability you can be much bolder than if you are at adverse vulnerability.
Alongside the vulnerability also make sure which seat (i.e. 1st /2nd/3rd/4th position) you are in. e.g. It is much more advantageous to pre-empt in 3rd seat than in 2nd.
So… please get into the habit of always checking before you get excited about seeing the goodies you have been dealt!
