re: Poker & Bankroll - small gains, big losses?
Sounds like you're putting your money in with the worse hand too often.
"Endless suckouts and bad beats"
Are you playing your hands aggressively? It's only a bad beat if you put all of your chips in the middle before your opponent had the pot odds
to call. Also, are you paying people off after they outdraw you?
If you are playing your hands aggressively and adequately protecting your hand then bad beats will still happen, in fact they'll happen more because almost every time the chips go into the middle you will be ahead and there will be more opportunities to get outdrawn. The wins will more than make up for it though.
"having my bluffs called by pocket 2s"
That's your fault, not bad luck. The other night I called an all in shove on the river with unimproved pocket 2's, I don't consider my opponent unlucky; I consider him bad at bluffing. Not saying you're the same as him, just saying that bluffing and calling bluffs is skill based, if you're getting called too much then you've got to improve at it rather than consider it bad luck. Possibly drop it altogether for a while, I think it often costs a lot more money than it gains at low stakes anyway.
"having second best hand"
That's the fastest way to go broke, when you keep getting dealt good cards but someone else keeps getting better cards. Sometimes there's nothing you can do but take the losses until things turn around, but you need to learn to make a big fold to reduce your losses. It's probably harder to do that online with fewer tells
available to you, but you can always restrict your starting hand requirements a bit so that in hand over hand situations you have the better end of it more often than not.
"draws not completing"
If you're priced in, you've got to go with it.
Not much you can do.
If however it's the result of semi-bluffs gone bad, then stop semi-bluffing and just check-call.
K9 vs KK is hard to get away from, you can't be blamed for stacking off with it but that doesn't mean it's not possible to get away from it and that you should accept it as beyond your control.
Losses happen, that's part of poker. Sometimes it's just dumb luck but more often than not it's a skill error rather than a luck issue that's at fault, always try to put the blame on yourself before anything else and see if there is anything you can change to either reduce the variance or even gain an advantage in a situation where you'd been putting yourself at a disadvantage.
