That's a lot of time you spend playing.
How do you deal with the frustration of losing so many hands you were statistically expected to win? I assume you're winning more than you are losing, though.
i'm not the person you're quoting.
however, it's all about looking at the long term and maximizing your value for your big hands. lets say, on average, you get it in with hands that have 75% equity either preflop or postflop. well, you can expect to win 75/100 times in those situations in the long term. even if you do lose 25% of the time, you're making a ton of value.
at the same time, you try to avoid spots where you don't have has a much equity or even less equity. so, maybe in 50-60% equity spots, where you are break even or slightly ahead, you're more cautious about stacking off in these spots unless under very specific situations like you're short stacked. and in spots where you have < 50% equity, you try to avoid these spots as much as you can. it's not always going to work but you do your best to avoid them.
so, by setting yourself to play hands where you have more equity than your opponent most of the time, you're winning a lot more often. but you also lose a lot of the time. with 25% equity, villain is still winning 25k hands/100k samples. and lets not forget all the other hands you might have to fold preflop and give up some blinds and/antes, or hands you open and fold to a 3bet or hands to open and have to check/fold the flop. so, you are losing/giving up a lot of hands, but you're still setting yourself to be profitable in the long term with strong hand selections that you play.
as far as making money, you go for max value in spots where you have a lot of equity to make up for the times you lose. so, going back to the 75% equity preflop, if you risk $1 to win a $2 pot, how much value are you getting?
ev = [$2*.75] - [$1*.25]
ev = 1.5 - .25
ev = 1.25
so you're making $1.25 each time
but lets say that, because you're losing or on a downswing, you want to risk less and you only risk .25 to win .50 instead. well, then you're only making ~.32 per hand. or .93 less.
in poker, the object is to make money off of bad players. yes, some achievements are nice like final tables and winning mtts, but profit is the number one reason to play for most players. so, if that's the goal, you have to set yourself to get maximum value. you might think you're risking less and can counter the bad beats and downswings by betting smaller, but you're losing a lot more value in the long term.
in the example, out of 100 hands, you're giving up $93 by not betting the full $1 instead of the $25 you're losing 25% of the time. that's $68 you're giving up.
