Sng draw - rien en BB et couleur apres, 2 question

[b]Bonjour

quand on est de BB avec pas grand chose en main, quelles cartes dois je changer?
si on touche un bon jeu comme ce que j’ai eu, est ce que je dois tenter le check raise comme j’ai fait et qui n’a pas marché ou alors j’aurai du betté directement?[/b]
