Hero ???

Reads: CO is a fish/CS...at this hand, he'd reloaded 3 times (each time for $1) and he kept going broke...he had 75%vpip and Went to SD 80%. He'd raised hands like A9s from MP and 3bet A7s from BB...He could have anything, but probably Axo or something similar.

Button was 49%vpip with postflop Ag of 1.7...went to SD about 40% of the time...

I figured there was a great chance I was a head at this point...but given the flop action, is it better to check to the flop capper so I can check/raise him or just value bet this all the way down...thoughts?

I agree with derf.
At first glance, you are against too very loose aggressive players with bottom two pair, so you have a monster.
But when you read into it further, the button's betting pattern either means one of two things:
1) he has a monster like top two or a set
2) he has a monster draw

This is like the most drawless any board can be. So ya gotta conclude you are behind the button a major % of the time. The CO I am sure you have crushed, but the problem is that if he has an A he has some hidden outs against you (like if the river is a three) and he will probably come along for the ride, so I don't like your overall odds of winning this hand.

Ok, I must really be screwing up my game. I thought GT would help me play better because my WR was down and I know i've been screwing up some hands (as is obvious from the hands I've posted). So I picked 2 hands from my session this morning to post where I used the data from GT+ to help me make decisions and I still made the wrong ones...

In this case, I'd seen CO play very agg with hands like bottom pair and weak aces (even if he didn't hit his ace)...and button was basically the same way...

I had the data (and specific memory of particular hands) that these guys could/would play this way with the crap that they had and I still screwed up my playing...

As stated in the other post, i may take a brake until I fiinish rereading SSHE again. There is apparently a huge leak in my game that I'm having trouble identifying (let alone plugging)....
