Agreed. With an M of only 4 and paying the blinds next, I would go all-in with ~18% of hands:
22+, ATo+, A7s+, KJo+, K9s+, QJo, Q9s+, J9s+ T9s.
I would much rather have the same hand SUITED instead of unsuited, e.g., KQs >> KQo. While a suited hand may not seem to have significantly more equity against a RANDOM hand than its unsuited counterpart, what matters more is its equity against the range of hands with which somebody will call the all-in. KQs does quite well compared to KQo against the types of hands that make up a significant percentage of calling hands, such as big aces and pairs.
Vekked;231103 wroteYou guys are wayyy too tight. You should be shoving at LEAST as light as A8s, KJo, ATo, 22, Q9s and T9s. Also, suitedness still very much matters when shoving pre-flop, since it could be the difference between a shove being profitable or not. The extra 2-3% equity goes a long way when you're pushing thin edges to begin with.
