First, the aggrodonk's strength is he beats you over the head with variance, and profits from players that fear variance. Sometimes his draws will come in, and when they do he will sometimes stack you. This is not something to be afraid of. You will make that money back five times over from all the times he stacks or nearly stacks himself bluffing at you, and you can call down with top pair and win.
Suppose the aggrodonk raises to 4BB as usual in MP1, and we flat on the button with K
T
, and the BB flats too. 100BB effective stacks. The flop comes 7
8
K
. There's no way we're folding against the aggrodonk here; we're going to call down our top pair all the way. Aggrodonk bets 8BB, we call, BB folds his 55. Pot is now 28BB. We definitely don't raise here, because the aggrodonk has nothing WAY more often than he has a spade draw or any made hand. We call to encourage him to bluff again.
The turn is the T
. We improved to two pair, but it wasn't a good card for us; now there's three spades and a couple of straight draw possibilities on the board. The aggrodonk bets 20BB. I advice against raising here, because it's STILL far more likely he has nothing or a very weak made hand, and will fold if we raise (he fears the spades, too, if he doesn't have them himself!) In fact, it's almost certain he's going to shove any non-spade river (and even a spade river sometimes) because he figures us as weak and thinks he can represent a flush/straight and push us off. So there's more value for us just flatting him and then calling his river shove. Sometimes he'll show us a straight/flush and win. More often he'll show us nothing or one pair and lose.
