Vacuum game is basically how you SHOULD play versus different population densities. For example at 25NL with
KK on 964 I can probably happily b/f versus anyone readless. At 1kNL versus an
unknown this
fold would be a huge mistake.
Another example would be minopening the
button 100% at 200NL because a lot of the players are playing too
tight. At 2NL though we 4x the
button with a tighter
range because everyone is playing way too
loose. If you do this in vice versa you will be cutting hugely into your
winrate.
This is why your "vacuum" game sucks. You are doing something absolutely terrible versus almost any
villain and will only be playing correctly versus a very small % of the population. Once you realize this and stop trying to do what seems "optimal" if our opponent were to play
standard(not to say your
standard strategy here is even near optimal versus
standard play) you will print lots of monies.
edit:
back to the hand in question. the only people folding with worst on this
flop are weak
tight players who are going to take free cards with any draws they might have(this is a disaster). checking is going to get us 2barreled off all the shit you want to
check in this
spot or like I said they'll take a
free card. aggressive players basically play perfectly v us and weak players play perfectly v us. when people are playing perfectly v us we are lightning money on
fire.
now you might say but we get to
showdown with
Tx/
JJ/
QQ. Okay you might but those hands would have called a bet and not bet at any point themselves anyway after the
flop
