New guy with a couple questions.

[cold_cash]

Hey guys.

I'm mostly a limit player but I've recently been playing more small no-limit tournaments. (In the home games I play this is almost exclusively what they play, so I'm trying to get better.)

Anyway, I've recently read both of Dan Harrington's books and I'm sort of feeling my way through some situations that I've likely been screwing up for a long time.

Many of these situations deal with calculating pot odds and, more importantly, what to do once they've been calculated. Even though the principles are the same, the differences in this process in a no-limit game vs. a limit game are something I stuggle with.

In retrospect this hand looks like a pretty simple call, and it may not be the best example to get my question answered.

Even so, I'd still appreciate your input.

Party Poker No-Limit Hold'em Tourney, Big Blind is t150 (6 handed) FTR converter on zerodivide.cx

UTG (t2425)
MP (t280)
CO (t880)
Button (t440)
SB (t1355)
Hero (t2620)

Blinds: t75/t150
Initial pot size: t225

Preflop: Hero is BB with 3[img]/images/graemlins/spade.gif[/img], J[img]/images/graemlins/diamond.gif[/img].
3 folds, Button Moves All In for t440 , 1 fold, Hero....?

So there's 665 in the pot and it costs me 290 to call, so I'm getting ~2.3:1.

This is automatic, right?


Another important question:

How does my stack size effect this decision?

For instance, if I had to risk 50% of my stack to make this call as opposed to 12%, is it still automatic?

Thanks.
