First thoughts are that opening 22 should be fine UTG in these games but that sample size is far too small to be the reason why.

I think you should bet slightly bigger on the flop as your default play with your whole bettting range. On the flop I dont think this a board that slowplaying will be correct with many monsters given how the Axx flop hits your UTG range so he should be check raising most of his monsters on flop or turn. Given that, at micro stakes, weak players LOVE slowplaying so it wouldn’t surprise too much if he had 97, A9, 99, AA given how hes risking about 7-8 times the pot to win $2.

Overall, at the micros, huge overbets are generally super nutted and rarely bluffs unless its the perfect card to represent. It essentially comes down to whether or not he plays KQcc this way. I would like to think I would fold against an unknown but you can still have AA, A9, 99, 97 so its not like this is the top of your range (although its obv close). He’s never making this play as a bluff, as he could just bet $5 and fold to a shove if he wanted to overbet bluff. This is probably AA to be fair.

Also, why not just play 3 tables and not auto pilot? Your aim should be to improve as a player and climb out of the stakes as opposed to grinding out huge volume.
