M. Bison SF6 combo: easy. 2LP is a 4 frame light button with low pushback that can begin a chain hitconfirm. 2LK is a frame slower with more pushback, but…
2LP/2LK > 2LP > 5LP > 236LK/[4]6LP / 2LP > 2LK > 5LP > 236LK/[4]6LP/214PP / 2LP/2LK > 2LP > 5LK > 214LP/[4]6LP
2LP is a 4 frame light button with low pushback that can begin a chain hitconfirm. 2LK is a frame slower with more pushback, but hits low for a better chance at opening up the opponent's defense. 5LK cannot be chained into, but has enough speed/range to link reliably in most hitconfirm routes. However, compared with 5LP, 5LK has a longer hitbox range and guarantees that the combo hits in more situations. The specific chain routes listed above are generally the best in terms of consistency on hit and block. Alternate strings like 2LK > 2LK > 5LP have more pushback and larger gap on block that will trade if the opponent mashes a 4f button. Note that an attempted link to 5LK can be interrupted by the opponent on block, making it less suitable in pressure strings. Ending with Light Double Knee Press (236LK) will leave the opponent standing and M. Bison at +2 frame advantage, in perfect range for a strike/throw mixup. This is the most consistent ender, and is the easiest meterless ender that reaches after chaining 3 LPs together. Ending with 214LP grants a knockdown that plants a Psycho Mine on the opponent. Linking into 5LK is the only way to achieve this from a 3-light hitconfirm, but 5LP/2LP can combo with 2 lights at close range. 214PP also works consistently from any canceled light, giving better cancel options for SA2/SA3 and midscreen oki for 2 Drive bars. Ending with [4]6LP grants a knockdown at +5 frame advantage with a forward dash by M. Bison after the light psycho crusher. This frame advantage allows M. Bison to do a safe strike/throw mixup. Besides, ending with [4]6LP has the highest damage among all the light confirm combos, making it the best mid-screen light confirm combo for M. Bison. To complete the combo, it requires to maintain the back charge for at least 45 frames while confirming with lights. Any Counter-hit Double Knee Press can combo into lights unless spaced too far out. For consistency, end with 5LK > 214LP/[4]6LP.
