Hmm. Now that I think about it I think my bet sizings look pretty weak especially on the turn it’s kind of an underbet. A TAG could pickup on it and exploit which is what I think he was trying to do by check raising.
His raise isn't a big one. It's just above the min-raise. This gives you a great price to call : 75€ to win 388€ or 20% pot odds. You need 20% equity to be +EV.
Also could he do it with KQ (or worst KX) ? Could he do it with OESD? OESD + pair ? Could he spazz out ? There are many worst we can see here. And you only need 20% equity. AK v. 99, 66 and 98s has 26% equity - which is kinda the worst scenario.
(I consider a labelled "TAG" Villain to be able to bluff / raise draws)
And stacks on turn are 193 into a 178€ pot in a 3bet pot after a half pot size c-bet. I'm fully for the underbet - but then you also have to realize it may trigger some reaction.
AK is probably the 3rd nuts you can have here - after KK and AA - so you shall never fold it.
