I urge all readers to download PokerStove. It is a very useful tool for evaluating hands vs ranges. Maybe by running a few hands you'll see how I think about situations where I am reraised.
I rarely put my opponents on "a hand" - rather I put them on a range of hands and then assess the value of my hand against that range.
In preflop scenarios where I get reraised I generally ignore bluffing and put my opponents on 1 of 4 ranges.
The ultraloose reraising range typical of top higher limit cash game players: 22+, A2s+, K9s+, QTs+, J9s+, T8s+, 98s, 87s, 76s, 65s, 54s, A2o+, KTo+, QTo+, J9o+, T8o+, 98o.
Against these players gambling hands like AJs, KQs, QJs and small pairs are about even money:
QJs = 49%
KQs = 51%
AJs = 61%
44 = 49%
Tightening that range up a little bit yields what I call the loose reraising range typical of late-stage tournament play: 22+, A2s+, K9s+, QTs+, J9s+, T8s+, ATo+, KTo+, QTo+, JTo.
Here the marginal hands get to about even money:
QJs = 45%
KQs = 51%
AJs = 56%
44 = 46%
KQs fairs about the same against a tighter reraising range but QJs, AJs and small pairs fall off somewhat.
Removing some of the low pairs, suited connectors, lesser aces and easily-dominated two broadway combos yields the tight reraising range of: 77+, ATs+, KQs, QJs, JTs, AJo+, KQo.
Now you are getting into very marginal situations with hands that will be very tough to play post-flop:
QJs = 36%
KQs = 41%
AJs = 44%
44 = 39%
Clearly you are getting on pretty thin ice ...
Removing more pairs, AT, AJ and modest two broadway combos yields the ultratight reraising range of: TT+, AJs+, AKo.
Here is where the most common "marginal calling hands" flatten out to 2:1 dogs:
QJs = 32%
KQs = 33%
AJs = 33%
44 = 34%
So when facing a reraise or an all-in apply a reasonable range for your opponent and ask yourself whether you want to get involved with shit hands like AJs, KQs, QJs or small pairs ...
