Poker can be played online with unlimited stakes.
Plus no taxes.
Lol at 'no taxes'. The 15% tax on online gambling operators (resulting in players getting 5 VPPs per $ of rake instead of 5.5 and similar rakeback cuts at other poker sites) has to be taken into account, as well as the cost of living (which is however quite low outside of London
). It's not an issue for MTT players, whose ROIs are way bigger than the rake, but I assume OP is going to play faster and thus rakeback-dependent formats (cash, Spin & Gos aka Jackpot Poker - there's no more money in conventional SnGs).
I've heard Birmingham live games are soft, though; it's a pity that games higher than £2/£5 run seldom outside of London. The latter is packed with strong opponents, and in general, I've heard that live games in continental Europe are generally softer than in Britain.
European countries are also gradually starting to smother online poker earnings with special operator taxes or VAT
(Leave alone those countries where player pools are segregated from the rest of the world - Spain, Italy, to some extent France, though the latter allows foreign European residents to play at its sites.)
There are plenty of countries whose governments are too inefficient to levy taxes from poker players if the latter use obscure withdrawal schemes (e.g. there are Argentines who specialise in swapping Stars $ for cash-in-hand pesos for a vig that's much smaller than the tax; I still wouldn't live there, though, because Uruguay is nearby and it doesn't tax offshore income).
There are also a lot of countries where there's no tax on offshore income (or at least on income that isn't dividends or similar) or where the poker operator tax is going to be lower. Currently, Costa Rica seems to not be going to tax income from poker sites in the near future. Panama isn't taxing it currently, but there are talks about a 5% operator tax, as well as in Guatemala. What the tax will be in other Latin countries that are going to regulate gambling is yet unknown to me, but I assume it's going to be less than 15% in those of them that generally have lower income tax than in Europe, e.g. Paraguay.
As far as I understand, in Canada, there have been successful precedents in courts where poker pros were able to have their income tax paid back because it was ruled that they are casual gamblers and non-professional gambling winnings are not taxable. For such a ruling, it helps when the plaintiff has a 'real job', which is going to be the case for OP. It's still tricky in Canada, though - normally one has to pay the tax (if asked to do so, which happens seldom and to the big winners only) and then file a lawsuit against the Revenue Agency (CRA).
I've heard it's even easier in Australia, i.e. poker pros are usually considered casual gamblers and not taxed on poker income by default, are they?
Caveat: if I were a US citizen and would like to play poker professionally, and if I were earning more that $100K a year (that's how much foreign income can be excluded from taxation under the FEIE rules), I'd lean towards obscure countries that don't submit to FATCA (i.e. aren't eager disclose income of US citizens, who're theoretically obliged to pay tax on worldwide income regardless of where they are) and especially countries that award citizenship easily (Paraguay comes to mind as a relatively easy option if a good lawyer is used so that the 3-year wait doesn't become eternal because of bureaucracy) in order to get rid of the US one and thus the tax obligations.
