Preflop
Standard open, standard result.
Flop
Yes you need to raise bigger. If he is bad enough to donk lead for 9k into a pot of 47k with a hand like A6, then he is also bad enough to pay more than just 20k to see the next card. Just keep the amount, which you raise to, smaller than the pot for psycological reasons. I would probably go to around 40k setting it up for an easy river jam on good runouts.
Turn
I dont understand this check back? Top pair is now trips and will never fold, and while you dont want his spades to fold, you can keep them in by sizing down a little bit. I typically bet half pot in a spot like this. Very few people can fold a 9 out draw on the turn for half pot, even on a paired board.
River
You trap worked, great! Now you need to get it in. Leaving yourself 6BB behind is missing out on heaps of value, and is another pretty big mistake.
Results
Just a standard cooler. Whenever your boat runs into a better boat, you are usually going to go broke. But so is the opponent, when the roles are reversed, so in the long run its just a wash. Also if he can have A6 or A2, he can also have A3, A4, A5, A7, A8, and all those hands are going to be played the same way. So stacking off your boat is still printing value in the long run.
