Last time I explored the problem of playing medium-strength hands on an untextured board depending on the style of your foe. But how should we adapt our game when the board is textured? Let’s say you hold A♣-K♥- 9♣-3♥ and the flop comes A♠-8♦-3♠.

The problem here is that two spades have fallen. Your primary obligation is to protect your hand, so you need to make sure of two things: 1) if your opponent does have a flush draw, you make him pay for it, and 2) you protect yourself against the nasty decision that will arise on the turn if a spade hits.
