Testuo ...
Good grief, you are indeed convinced! Thanks for the reply ... as I said, the jury is still out for me... (and even further out following your post)
A few points in response:
(1) I've considered substituting Axs (or 2 x broadway) as my bluff cards ... that would probably be just as good. I guess I'm less convinced by my ability to get away from hands where I hit top pair, weak kicker!
See also some very drunken maths, later...
(I view QJ and QT as connectors, so I do sometimes raise with them. Cards that hit these hands are also likely to have hit hands of callers, though)
(2) If I flop a draw and choose not to bet, it's because there's something about the board or opponent that's scared me into checking - so I'm giving up on the hand unless I improve, and therefore don't care if I'm bet into on the turn. Having the bonus of sucking out 20% of the time is quite attractive! I've invented some numbers below, for the case when I bet and are called - something similar applies in this case.
(3) Flopping a straight is equally unlikely whether or not I raise, of course! Say (for example) that a raise increases the chance that I stack an opponent to 50% from 25% (both by disguising my hand and by putting more money in the pot), then that 1% chance translates to an extra 0.12BB/raised hand (assuming 50BB stacks).
(4) I'm pretty sure stealing with pocket pairs is in general a bad idea (because of the high chance of flopping a hand that beats lots of other hands).
Even a very simplistic set of calculations is too much effort, since it would need to take into account the difference between limping and letting in other people (but having to fold if you didn't hit), and raising out people who would have paid you off if you did hit.
But I am pretty sure!!
(5) Finally, I steal raise much less on Party (25BB stacks and whackier players) than on Full Tilt and Paradise (50BB stacks)
SOME MATHS
[EDIT: tidied this up]
Say I livepokerforum (tm) after raising (to 4bb=big blinds), and get called ... what is the benefit of having suited connectors ...?
With no chance to improve... I lose 13bb (4bb raise + 9bb flop bet).
Lets look at the difference in how much I lose when I have some chance of improving:
(1) Suited connectors
OK, so I have like 20% chance of flopping a straight of flush draw?
With a 20% chance to improve the turn 20% of the time, and assuming I get another 20bb on average if i do...
I improve to -11.1bb ( (5 + 9 + 20)*0.2*0.2 - 13*0.96)
And considering two pair, 0.05 of the time I'm paired on the flop (33%), I get to an expectation when called of -10.3bb
(2) Ax suited
this is a bit more complicated, because it depends on whether an A flops ... here's some attempt to work it out ...
An A high flop (I'm called): 30% chance, I need to hit my kicker on the turn (5%), in which case I'll get maybe another 20bb as above, so combined result is -10.6bb
Non A high flop (I'm called): 70% chance, I lose 13bb unless an A turns (5% chance), in which case I get no action (I win 14bb), so combined result is -12.3bb
Combined Ax offsuited expectation when called is -11.8bb
(the probabilities aren't quite accurate as I'm watching MOTD at the same time as doing the sums)
10% of the time I'm 20% to improve (but I'll probably get less than with suited connectors since straights are less easy to spot ... say 10bb extra, 24bb in total) ...
So the expectation when called with Axs is -10.9bb.
These scenarios are all slightly simplistic and highly speculative, eg I've chosen to ignore the times when I get outflushed (as balanced by the times the flush draw doesn't make it, and I bluff the river to win).
But does provide some sort of mathematical evidence that raising with suited connectors isn't completely stupid compared to raising with Axs et al
