Entering in the game from cutoff is o.k,but as close to BU as possible.
Without any doubts you should play this hand very aggressively-you have made
hand,still vulnerable ,you should protect it -standard 2/3 pot size raise if you first
to act,if was bet,then pot size bet or even all in.You should do pot odds to your opp unfavorable ,then if he calls he is looser in long term,even you lost in short term.You have outs too,you can catch full hose or quads.Reread SSS articles -free
play from BB and don`t miss this not often good chance.
Good luck .
