it all comes down to what you are comfortable with. in general, playing deep (250bb as opposed to 100) means you have more options - and are likely to win even more when you do win. you are also likely to lose more though, so perhaps the best option would be to compare how you do in big pots - do you win most, or do you lose more? basically, while playing deep, you should value some hands differently - the low pairs, the suited connectors, etc. all become more playable. note that this is not all about your stack though, you should also consider the opponent's stack.
Okay thx I'll keep buying in with 5$,
One more thing, Is it smart to reseat at a table when you won a 10$ pot for example? just so you make sure you don't lose it all right after?
My friend suggested this to me and I thought it might be a good idea,
Any thoughts on this?
if you plan to lose it, then sure, it is a good idea. then again, if you plan to lose it, why are you there at all?
basically, the decision to stay or go should NOT depend on your stack (and neither should you think about "what the others will think of me", as MediaBLITZ seems to suggest). factors to consider are (most importantly, there are others of course):
- number of fish at the table (you generally want to play deeper against fish). if there is only one fish with a small stack and the rest of the people seem better than you are with deep stacks, that is probably a good time to go. if mostly everyone is a fish, stay by all means.
- position relative to the fishy players - if you are before them, that may be a factor to get out. if you play after them most of the time - stay.
- how deep the fish are, and how often stacks tend to get in the middle... obviously to both the idea is "the more, the better".
- table image... although that should probably not affect you at 5nl.
