No. You have the nuts, there are 2 spades out there, you don't want someone drawing out. Even as it was the OP was ahead when the money went in. That's what you want, but on the other hand if it went the other way where you had TPTK plus the nut flush draw you're not folding that either. Nothing you can do there, that's poker.
Seems there is one thing many online players do not realize nor understand when playing nlhe for cash, at any level. That is - the premise of "being ahead when the money went in".
That IS what you really want, but so many times we see comments posted that it wiped out an entire
bankroll when the hand went bust. That's great if you have no problem grabbing that credit card and reloading, but seldom seems to be the case. It's a bankroll built up over time.
Not everyone is going to 'hit it lucky' or have every 'dominant hand' hold up, yet they are willing to bet the farm - lock, stock and barrel on that happening. Just my opinion, but getting into a 25/50nl with an entire BR is NOT a good move. Stay with the smaller stakes if $50 or so is all you have posted with the cashier. If you've tripled up or more, get some of it off the table, IMO.
Sure, winning $30, 40, 50 pots is exciting. You double or triple up, but also put EVERYTHING at risk. Poker is a risk game, but not when just 1 or 2 bets can wipe you out. A poker pro may have a $2mil BR for playing, but you won't see them bring it all to one table. If their 'best hand' gets busted, they reload and move on. They have a BR that favors playing
odds, percents, marginal hands, whims, and the like.
Small BR? Stay with small stakes. You lose? No problem. Reload. I have a small BR (built from FR winnings) and would dearly love to play the 25/50 games, but I will wait until my $1 tourneys or 2/4, 5/10 produce a larger BR to back up my play - and my losses.
Bet big, or go 'all-in' when you are ahead, but do it with <5% of your BR, not the deed to the farm. If I lose the $5 or $10 I brought to the table or the $1 on the buy-in tourney and bust out, I'm busy reloading or finding another game to 'play on'. It beats not having anything but time to write in blogs or forums about my BR being all gone.
There may not be a hole in your game, just the fact that nl games attract many 'win big/lose big' players. It's the nature of nl games and when you look at the 'odds or percentages' on a hand being a winner, remember always that there IS that downside percentage.
Some days you're the windshield, some days you're the bug.
