i've been trying to play 40 lines mode in lockjaw without using the hold box, which has it's ups and downs. i find that i fall into a state of constant indecision when i use the hold box so i end up using it excessively, causing me to think too much. another disadvantage is that it can add more keystrokes (but not necessarily). it could be used only in situations where to place the current piece in a good spot would take 3 or 4 keystokes, while the piece it could be swapped with may only require 2 keystrokes (hold + drop). the question here is how much time is lost in deciding whether or not to swap the pieces. i suppose hold is also helpful for maintaining a stacking pattern you're familiar with. this could potentially save time because you would do less thinking. i think we could all agree that after 35 lines you do whatever you can in an attempt to clear the playing field when you reach 40, even if that means using hold multiple times. what is everyone's strategy before that? is anyone disciplined enough to use hold only when necessary, while not considering it the rest of the time?
