The key decision needs to be made Preflop to avoid getting into spots like this.
You are asking for trouble against a player as tight as 11/8, you will be dominated too often if you hit top pair to make it worth while. So fold preflop to this player type.
You call call all day against looser players with this hand.
As played its not the worst call if you think he could bluff a missed flush draw. Sometimes you will be good here against a looser player but that is why you are calling,,,to pick off a bluff with your bluff catcher not because you think 2nd pair might be good against this player otherwise.
Start thinking about his cards rather than just yours and give him a range of hands based on his stats.
11/8 is really quite tight/nitty so there will be a lot of aces in his range, in fact at least half of his hands will have aces and a quarter of those are going to have either the ace or king of spades.
So when the ace arrives on the end you are certain to be beaten half the time just by an ace. You will also be already beaten by AQ (6 combos) KK (3 combos) AA (3 combos) and any flopped flushes AKs AQs AJs ATs A9s are all in his range.
Remember this as a guide....."Don't get stacked with 1 pair"......
Once someone is sticking all their chips in the middle 1 pair is nearly always beat especially so when you don't have top kicker.
You should only ever call against total beginners who are overvaluing top pair bad kicker or 2nd pair or maniacs bluffing
Here the villain is tight you have no reason to think you are good, so as played fold the river and pat yourself on the back for saving money
