which club(s) do you plan on playing at in portland? if youre good at MTTS encore(which has crappy parking) and final table both have pretty decent guarantees on some of their tourneys. final table has a 20k first friday of every month i believe. buyins arent too high, fields arent too tough overall and a bink in 1 of em could give your roll a real nice boost in the right direction, only play these though tho if you have alotta experience in tournaments. as far as cash there are some really good 2/5 games that get off in different parts of town different days of the week, while they are juicy they also contain a few beasts so probaly best to avoid taking shots in those till your roll is atleast over 10k cuz while they are 2/5 blinds some of em play really deep. when you do jump to 2/5 maybe try out final tables 2/5 game at first cuz i believe they cap the buyin@100bb's($500). spirit mountain has a 2/5 game that runs on the weekends and while its definitely beatable i think it is run with no cap so probaly best to avoid that as well till your roll is super healthy. as far as 1/2 goes avoid the coast casinos and paying their rake(which is awful raking the sb before the cards are even dealt) and stick to playing in pdx. most 1/2 games are soft overall all over town just like 1/2 anywhere else in the country youd play live and youre only paying 10 bucks a day as opposed to rake so your winrate should be much healthier than playing 1/2 in a casino. there are also some supersoft games that are run in select strip clubs believe it not different nights of the week, those could be really good for building your roll if you can deal with surroundings
last but most importantly i definitely dont wanna tell anyone not to follow their dreams but you listed your bankroll as only 1k. are you still working, can you add to/replenish this at any time? sure you can start off on a heater and run it up but most likely youre setting yourself up for failure. your limit HE experience will def help you as far as reading players,understanding position etc but you are inexperienced you said at NL and alotta things will be foreign to you at first and youll be put in alotta spots where you are clueless. i said the games are very beatable in town and they are enough so that a really good experienced player can make a living off them in portland(lol which isnt a cheap city btw). you spoke of variance so you know about that and it can affect even a great player in soft 1/2 lineups and wipe a 1k roll away like nothing so again its important to keep a regular job while youre working on your game and grinding up a roll at the clubs in town. hopefully you get to the point when you grind up a 10k+roll with several months living expenses saved up seperate from that and then maybe give it a crack full time. good luck!
