No Never, always play the same way that you would play them otherwise! (But, I will say if they're not suited, then be careful! (especially going all in pre-flop) Better to be safe then sorry!
However, if theres a raise and a reraise before me , then i might fold them pre-flop, especially if theres a short stack or someones about to blind out... in that situation it may be safer to fold them and wait for the bubble to burst. It really depends on my chip stack in relation to others, if im large, and have over 50 big blinds, and there was no raise or reraise or rereraise, then definitely calling another players all in, or shipping it. On a side note though.. Im not one to call another players all in, unless i have good pot odds, and or can truly afford it, like if I had 50 BBs and it only cost me 4-10 BBs to call, then im probably gonna call.
You should also be putting people on "Ranges" and learning more about their ranges by watching hands that youre not in. Typically you want to do this
before finding yourself in an all-in situation pre-flop, so that you can have a good idea of how loose that player is playing. Also, I like to have control of the hands i play in if i can, i do this by controlling the betting. So, if someone ships it on me preflop, im not in control, they are. So i guess what im saying is, its alot easier for me to fold AKo pre-flop if someone else has went all-in before me...
Hope this helps!
