suited connectors fit his style very well. as previously mentioned, they are played in an effort to bust big hands and win entire stacks, as opposed to winning small pots with aces or kings. both are equally good hands, but monster hands rarely rake monster pots.
another note on doyle's play:
doyle (and many other top players) plays a lot of "tricky" hands, and therefore most of their thinking is done on the flop. they can be loose preflop but all their decision making is done after the flop. these are the people who "outplay" others. conversely, new-to-intermediate players use preflop hand requirements to govern their play, so all their thinking is done preflop, and
odds dictate their play moreso than "creativity" or trickery. both styles are equally valid, but the top players can switch between the two, so their arsenal is more robust than most other players. the reason intermediate players go broke often is because they emulate doyle et al preflop, but lack the experience postflop where they must then outplay their opponents.
