I think preflop, flop and turn are standard. Comments on betsize appreciated.

River I unblock diamonds and block spades. I unblock AQ,AJ and block AT/KT. Thougths on river jam?

I'm not sure whether this is supposed to be a river jam or not, but I think the problem you're going to have is people have a tendancy to underfold when one or more flushdraws brick.

this has some sdv and you have many worse hands to bluff
I'd xf this, xc QT mby

Pretty standard up to river. The problem bluffing with your hand is that it has showdown value, so a check isn't bad. However, if you're range doesn't include many smaller suited connectors, you won't be left with a huge amount of natural bluffs. Any QJ, QT, and JT now have showdown value at least.

Basically, if T9s is the lowest suited connector you would 3bet pre, turning this hand into a bluff is a decent idea I think. Basically, what worse hands would you have that can take this line? I'm not sure there are any. If you have all suited connectors down to 54s in your range, then you have a lot of better bluff candidates. But I'm still not sure these will add up to the required number of bluffs. Also, it depends whether you are value shoving with AQ and AJ as to how many bluffs you need. Another point is that you would expect to fold out a decent amount of villain's hands which are ahead of yours, which is always a good metric for a bluff.

A final point would be that at the micros (and the lower the buyin, the more this applies), jamming on the river (and 3-barrelling in general) probably causes slightly more folds than it should, so slightly overbluffing the river is a good thing I reckon (although as another poster points out, this may be different when a couple of FD brick). All things considered, I'm not sure the play is optimal (I reckon it might well be, dependent on your range PF), but I do think it will be profitable.

I don't think preflop is all that standard, but maybe my preflop play is outdated. I'd much rather 3-bet light with a suited A or K that will block the types of hands that are likely to 4-bet us, or with something raggedy that has less postflop playability. We are getting a good price to call with a hand that will connect on lots of flops. It probably isn't all that important honestly, just my thoughts on preflop play.

Flop and turn are fine. River is weird. I agree with pjj that microstakes regs tend to overfold the river, which is likely learned behavior from people underbluffing the river due to fish overcalling, so levelling war stuff yada yada. We can exploit the regs by bluffing in spots the fish don't and causing them to overfold. In a tougher game we're not getting AQ to fold very often, but maybe here we will.

I don't think you have a ton of SD value here, as he's more likely to have an A than a draw, and the T hits the 2-pairs that will now never fold. I don't hate the bluff, but given that we did pick up a small amount of showdown value and the river being a good card for his range, I probably give up here and dance a little jig the time it checks through and we scoop.
