The "Move To Grid" setting (formerly "Tile Setting") is one of the most important settings in the entire program, as it determines exactly how SaT will separate the important tables from the non-important ones. This setting answers the question: "When will tables leave the stack and get tiled into the grid?"
1. Never - no distinction, stacking only
2. When action required - Tables moving to grid when its your turn to act
3. After entering pot - Tables moving to grid after you've entered the pot
4. On flop - Tables move to grid when the flop appears
5. When dealt cards - Tables move as soon as you are dealt cards
This option means that StackAndTile will not do any automatic movement of tables out of stack and into grid. You will be playing a normal stacked mode. You control manually how and when tables move. Tables can be moved to grid with a "Manually move table" hotkey and can be moved back to the stack with a "Stack table" hotkey.
This setting is useful for people who are used to normal table stacking already, and only want to move a table into grid when they decide that they need to pay special attention to it. For example, a sit-and-go player might be fine just playing completely out of one stack. But once it gets to the bubble, he'll want to pay more attention, so at this point, he can send a "Manually move table" hotkey to move the table to grid. Basically, it allows the user to only move tables when he chooses.
When action required
(This will feel more like using a normal 'tile' layout)
This setting means that whenever a table in the stack requires action, it will be moved out of the stack and into the grid. Tables are piled in the stack, but as soon as they require action, they are moved into grid. Therefore, all of your game playing will happen in the grid, and you will not focus on the stack. In this setting, the 'stack' is merely a placeholder for all tables that don't need action, so you can mentally 'ignore' these tables. The one exception, is when the grid is full of tables, and another table needs action: in this case, the table will come to the top of the stack for you to act (until another grid slot frees up).
Tables that have been moved to grid, will return to the stack if one of three things happen: 1. when you click the Fold button with your mouse, 2. when you send a stacking hotkey such as "Stack table" or "Fold+stack table", or 3. when the End of the Hand is detected.
After entering pot
(This will feel more like using a normal 'stack' layout)
This means that StackAndTile will move tables out of the stack and into the grid only when you decide to actually play a hand preflop. Here, you will be playing and making decisions in the stack, but only preflop decisions. If at some point you take a VPIP action such as Raise or Call, the table will be moved into grid. The approach here is: focus on the stack to decide whether to Fold or not preflop, and focus on the grid for tables where you've already chosen to be involved and play the hand further postflop.
SaT detects whether a VPIP action was chosen by the user either by physical mouse clicks on the bet/call buttons (if Left Click Detection is enabled), or by bet/call hotkeys. SaT has its own built in hotkeys to click the bet/call buttons, so if you press these on the table, it will be tiled and moved into grid. However if you prefer to use a program such as TableNinja for hotkeys, then in SaT, you'll need to set up "External VPIP hotkeys" matching those VPIP actions such as bet and call.
This setting wil move tables from the stack to the grid as soon as the flop appears, and you are playing the hand. This allows you to play all of your preflop decisions within the stack, and tables will only move if the hand reaches the flop. This setting will be similar to the 'After Entering Pot', with the difference being that your grid will have more free slots. 'After Entering Pot' will move tables as soon as you enter the pot preflop. But if you raise preflop and everyone folds, then the table will be in the grid unnecessarily. The 'on flop' option aims to solve this.
When dealt cards
If this is chosen, then tables will move into the grid when cards are dealt. This will initially feel like 'Zoom' or 'Rush' poker, however, you will only be able to send the table back to the stack after your cards have disappeared completely. Also, you should note that some poker clients will show your cards faded out with transparency even after you've folded your hand, when you hover your mouse over your playername. You should turn off this feature in each of your poker clients if you can, so that SaT will not mistakenly detect that as your cards being visible. Using this mode requires you to use preferred seating.
