So you're playing KQs and raise preflop. Flop comes 59Jr and opponent bets. You call and catch a K on the turn. Opponent bets and you raise. Opponent calls. Cool. And the river is an A. Opponent bets.

It's a good time to look at your post it note. Does it make sense that opp would bet an unimproved A (with maybe a 6 kicker) with that board? No. That heshe would then call a raise on that turn with just one overcard? No.

Nevertheless:

Your opponent has an ace. That's what heshe has. So you can stop wondering about it.

This will save you some heartache I think.
So, So True.
