I understand how frame traps leave a small gap in your pressure to allow the opponent to begin a move only to get counter hit. I understand they are important for pressure because they convince the opponent to block and let you just do high/low/grab mixup kind of stuff on them.
But why do they press a button? The only two situations I can think of besides them just mindlessly mashing are: crouch teching, and defensive pokes to stop you from walking back in.
But I only really see people talking about frame traps when you are close, after one or two blocked jabs. This leaves crouch teching as the only reason why I think they would would want to press a button within frame trap range.
Can I get maybe 3-5 different situations where someone would press a button and get frame trapped besides crouch teching? I play SF4 and also KoF, and KoF doesn’t even have crouch teching (although trying to tech kind of is still an OS)
